I have searched and also been in contact with XLR8 many times.
Background.
I have owned 2-2006 Acura TL's.
I am on my 3rd 2007 Acura TL Type-S.
I have installed just Eibach springs on an 07 TL Type-S.
I have installed TEIN SS & SA coilvers- ( when I used to have $ )
My 2007 MRP TL Type-S Has the A-Spec Pkg.
The A-Spec coilovers have my car lowered 3/4".
I want to lower it more with just springs.
When I bought my new 2007 TL Type-S, I installed
Just the Eibach springs and hated how they hit big bumps
Or bad RR Tracks... I Love the TEIN SS/SA Coilovers.
BUT- I no longer have a job that pays much. NO complaints.
Q: Since the A-Spec coilovers have shocks that are designed
To be lowered 3/4"- I don't want TEIN H-Tech springs because
They lower my car the Same as the A-Spec springs..
I was highly considering the TEIN S-Tech springs that lower
My car about 1.5" F&R. And since the A-Spec shocks are designed
To be 3/4" lower than OEM TL Type-S. I would "THINK" That the
TEIN S-Tech springs would be fine. I have been told NO from some
Who are considered to be "Experts". I would "Highly" Appreciate
Anyone who has a good "Suggestion" for this issue.
Please remember I want my care about 1.5" Lower F&R Using
Just springs-- But NOT Eibach Pro springs
Thankyou for any wise "suggestions".

I believe a member here "Guitarplayer16" has S-Tech's on A-Spec shocks. Try PM'ing him for more info.......

Close enough?

It sounds like we are in the same boat. I like the ride height of Tein's and probably others like it but it rode too harsh. Those springs are like 12kg or 672ft/lb. In my opinion the Eibachs ride ok, but they do not go low enough. If my notes are accurate, and I think they are, eibachs are 372 on the front and like "150ish" - 233ftlb max on the rear, those are variable rate. So you would need something stiffer than that if you want it firmer.

I am not sure if you can put a threaded body on the aspec shocks, but I know you can on Koni's.

My next thing to try will be something like this threaded body for my koni's:
Koni 30-0000-0005, Koni Spring Perch Sleeves and Kits | Koni

then add springs like this where you can specify the length and spring rate:
Ground Control - Eibach 2.5" ID ERS Spring


Also, there are other places I think on ebay to get a cheap threaded body, even comes with springs.

Here are some spring rate comparisons, but I have not entered Koni's yet.
https://acurazine.com/forums/tires-w...arison-784875/

Also, I have even been tempted to try some of those cheap springs from ebay because they are so cheap! And if you can get the right spring rate and lowering characteristics, I don't know why they would be any worse or better than all the expensive brands.. I mean its just wound metal rod.
https://acurazine.com/forums/tires-w...arison-784875/

Here are some cheap springs but the spring rate looks too low on the front.
http://stores.ebay.com/jpgenuine?_dmd=2&_nkw=tl+springs

To step up from eibach (at ground control), I would go up to something around 400f to 250r.

This doesn't apply to you since you want to keep the aspec shocks, but its note worthy to say that the bottom of the oem "type" springs sit below the perch, whereas flat bottom/top coilovers sit flush or slightly above the perch. So, in my case, to go to a threaded body on my koni's then I would need a shorter spring. That is where the customization comes in. However you may be able to specify from that link above the length and spring rate of a spring that is beveled on the bottom..

Chad05TL

Random info:
Tein springs are 7.8" long and Aspecs are 13" long = 60% the length of aspec. Shorter and tighter.. (front)
Tein Basis 12kg/6kg:
Aspec and Tein springs have a 14mm thickness coil. I measured it myself with my micrometer.

For springs, You will need inside diameter of 2.5" for koni or oem shocks...

Odds are: the shorter the uncompressed spring length, the higher the spring rate.. Finding the happy middle will be impossible, especially to get an even drop, at the right price... Unless you special order.



.

Chad05TL

And even then I bet it wont be possible without having a "threaded body". Because toying with the spring rate alone will cause different ride heights.. Let along changing the spring length. That's why you need a threaded body. Otherwise, your options are limited to what has been produced already..

I inadvertantly pasted "spring comparison" twice.. here is the cheap spring link. haha That's the best I can find on the cheap.. Spring rate on the front is a tad low.

WOW. $68 for 4 springs.
I have never seen those.
Thankyou much for your info
And the others.

Thankyou very Much Chad !!!! Awesome info
Having the A-Spec "coilovers". about .75" Lower than
A Stock 2007 TL Type-S.
My main question was how the TEIN S-Tech springs would match
The A-Spec "Shocks". The TEIN S-Tech springs lower a stock Type-S
About 1.4" F&R. the TEIN H-Tech lower the same as the A-Spec springs.
I have had TEIN SS & SA coilovers on other 06-07 TL's I have owned
Before this one ( in Avatar ).

Chad05TL

By the way, all those springs will be a "trial and error" type thing. I suspect the 300 spring rate is close to the oem spring rate. Eibachs are 372 on the front. And it says it is 1.25" drop so that's almost what you were wanting at 1.5". But like you said, you can only go so low on oem shocks, and still have the shocks be satisfactory. But still at the end of the day you don't know how the car will sit on it. Like eibachs? or something else? They are cheap but I have never seen them on a car or know how they handle. It does say "Cold Wounded Steel" so I guess that is a good thing. I have no idea what it is. Heck if you like them, I may try them too! haha They also have some other colors. Like red green and yellow. I think they are all the same specs. Lowering Spring, Honda Prelude items in springs acura tl store on eBay!

One other thing, if they are 1.25" shorter than OEM, and even if the spring rate is the same, then I would assume they would still ride a bit firmer because they would have to compress sooner and get tight faster since they are a little lower.. See? I think that logic holds true but I never tried it or do I have a way to measure other than SOTP.

Chad05TL

by the way, if your car is a manual shift then it might sit higher in the front compared to an automatic. So, be careful there. No one has tried these. And if you are concerned about wasting money, then I would warn against buying those springs because if they do not work out, then it will end up costing you more money to buy another set. or just be a waste of $68 plus the work.

You've got me curious about those Koni sleeves. I'm currently using the top perch, but I want a tad more height. Can those sleeves raise higher than the highest perch?

ExcelerateRep

PMing you back at the moment JD Hopefully someone that has done the STech Springs/ASpec Shocks combo can chime in with a review or their experience with that setup.

I would definitely avoid the $68 springs. Who knows if there was any quality control when they were manufactured! The Street Basis are on sale for only $531. If you can save up, I think these might be the best bet for you as they are cost effective and still adjustable.
TEIN Dampers - Street Basis - Excelerate Performance - Japanese and European Performance Specialists!!

Chad05TL

yes, but the spanner ring is flat, but any oem spring or spring to fit the perch on the Koni's, are for a spring that is beveled or not flat. So if you get a threaded body for the Koni's then you will need a new spring that is flat on the bottom.

I agree that the 68 dollor springs would be a trial and error type thing because no one on here has ordered those springs and installed them.

Nevertheless, IMO, Teins are too harsh. Its a short spring and 672 ft lbs. So its made for extreme low ride height because it is short and its very tight to keep the car from bottoming out. They engineer that spring to be suitable if a guy put his car on the lower threads. So it's tight. And I'm not the only person who says this. Sorry to say that the person I sold my Tein Basis to, said "I see what you mean".. I only had mine for about a month or less. I think JD has already had TEIN anyway..

ExcelerateRep

I haven't had too many customers give me feedback that the Street Basis are too firm, but I'll definitely take that into consideration if anyone inquires to their ride quality. I know the Street Advance offer 16 way adjustable damping so you can change the stiffness a bit and make them softer. I know the Street Basis have preset damping and it's about half way between stiff and soft. Obviously the best coilover to overcome this issue would be the Street Flex which features independent ride height, damping, and spring preload adjustment. They understandably cost more though, so it's really a matter of accomplishing your goals while staying within budget.

If you can swing it, I'd definitely recommend our XLR8 ISC coilovers. They have all the same great features of the Street Flex but we have them on clearance right now for $799! They also have 32 way damping adjustment instead of just 16 way.

Chad05TL

Tein SA and Basis (maybe the flex too) have the same 8 inch, 12kg spring. So I don't see how one is going to ride so much better than the other. Maybe a little but not a whole lot.

But If I did it all over, I would go with Koni's and a separate threaded body with a custom spring about 10" long on the front (not sure about the back yet). I have not tried it yet but I think that would get me low enough to remove wheel gap. And that's plenty low. I did have a picture of my car with Tein basis about all the way down.. And that was too low. Like 2" too low. Therefore, you don't need a spring that short. So, I say "order custom springs that are shorter than Eibachs but longer than Tein's and you "should" get the best ride possible in combination with lowering if you get a medium spring rate too.. Mix that with some decent sway bars and you'll have a good handling car and a good riding car. Don't want to let the springs do all the work to keep the car flat in a curve. That tight of a spring will just make it ride too rough. So, use a medium spring (length and spring rate) and a decent sway bar and you'll be fine, especially on a sports sedan.

Problem is, coilovers are made to go all the way down. So, in order to go all the way down, you have to have a short spring. And when the spring is that short, it has to have a high spring rate to keep it from bottoming out. So, since they give you the option to slam your car, that is how the unit is engineered. Otherwise it wouldnt work under those conditions. So,raising the car doesn't really help too much. It does seem to help a little but it wasn't enough for my TL. Because all I got was NOISE from the TL suspension. Thats not a "bad" on the coilovers, but that's just how these TL's have some clunking issues and the lower you go, the worse it is. Nevertheless, even if there were no clunking, it still beats up your car. A super stiff suspension also puts more twist on the frame because the suspension does not have room to absorb it. even just sitting in a parking lot where 1 side is higher than the other, on a stiff suspension, it forces the body to twist. And it puts a torque on the frame. Not good. Will cause new rattles and "premature aging". The reason I know that even sitting on uneven pavement can cause a twist on your car, it is because I have seen how my car sits in the same parking place at the lake when I go run, with TEIN's and also Eibachs. With TEIN's, the car has a very even wheel gap all the way around the car on all 4 tires. But when I installed the Eibachs, as I was sitting in the same parking spot, one side was a tad higher, and the oppose corner was lower. So, with the softer springs, the rigidity of the car was causing the car to pivot in 1 direction since the pavement was uneven. But with the TEIN's, all four corners were pretty even. So, with the TEINs being so stiff, it was actually causing a twist on the frame since the wheel gap was pretty even. The same thing can also be noticed while jacking your car up with a floor jack. Have you ever noticed that with stiff springs the car is much harder to jack up? That is because a tight suspension does not allow the car to rock back, or rock over to one side as easy. If you know anything about Static forces, this cause much more force to be applied to get one wheel off the ground and again, it put puts more twist on the frame rather than letting it roll into the spring on the opposite side.

So there you have it. More than 1 reason to not go too stiff or too short with a spring.
(Unless you are going for performance only and don't car about ride or keeping your car rattle free)

Chad05TL

by the way, this is neither "here nor there" but you said the "Basis have preset damping and it's about half way between stiff and soft"... Well, I think the Tein website says something like the SA's having 200% more dampening over the Basis. That would probably just make it stiffer if anything. It doesn't say that the SA's are softer AND 200% stiffer.... So, I don't know how the Basis can be "in the middle" if the SA's are 200% more.... So how do you know the Basis is "in the middle"? And in the middle of what..? What is your reference? Spec sheets?

I went with H&R Sports Springs. They're inexpensive with a respectable drop.

Thankyou all for feedback.
The first time I lowered a TL was my New 2007 ASM Type-S...
I put on Eibach springs which lower the car about the same
Amount at the Tein S-Tech springs= -1.4"... Back then No one said
The Eibach springs would blow my OEM Type-S Shocks, and
They didn't. So why would the Tein S-tech springs blow the A-Spec
Shocks that were designed to be -.75" lower ?
That's basically lowering the A-Spec shocks Only -.75"
I know all about Tein SS & SA coilovers as I have installed them
Both on 2 other TL's I had. When I had the Tein SS or SA coilovers
I ran the front shocks at the Firmest setting. The rear about 75%.
I found the Tein SA coilovers on Ebay for $650 with shipping- New.
As of this year I don't have money for coilovers. - No complaints.
I was just figuring I could get a new set of Springs for my A-Spec
Shocks for this year. I have installed many suspensions and have the tools.
Not bragging. Just the facts. Learned it All on AZ
The liked the lowering of the Eibach Pro springs I put on my first New
2007 TL Type-S. The ride was good "EXCEPT" on bad bumps or RR tracks,
Where I have never experienced that HARSHNESS-EVER.
This is just pure fact- The Tein S-Tech springs would Only lower
The A-Spec shocks -.75".. How can that BLOW the shocks ?
Tein S-Tech ?
H&R Springs ?
I just want my car aprox -1.4 inches lower. About the
Same as the Highest setting on the Tein SS-SA Coilovers.
I prefer Firm over double-bounce.
Thankyou again "ALL"

Chad05TL

I say try any style spring you can find if you think it may work. All I know for sure, is that if you go too low on a stock shock or even a "Monroe gas-o-matic", your car will double bounce. I did that once on a Camaro. It lasted about 5 miles.. and redo! haha It needs more dampening or damping the lower you go.


As far as avoiding a $68 spring, I think that if they collapse some, then it won't matter if you are on coilovers. like if you installed a threaded body on a set of Koni's. Also, regarding my comment above, since a beveled type spring may sit below the perch a little bit, whereas a coilover spring is flat on the bottom and sits even with the perch, it tends to take away some lowering ability, but then I forgot that these Koni's have a lower perch which can give you more room to work with as far as lowering the car... And still being able to have a "lengthy spring".. like a 10" spring.. I be it would work. And I am on the upper perch now. I still want to try that threaded body with some custom eibachs for my Koni's. But, before I do that, I gotta take this thing to a shop to see what the clunking is. Like a ball joint or something. And for some weird reason, the rear makes a similar noise. *sigh*

Update.
Installed the H&R Sport springs on my 2007
Acura TL Type-S that has A-Spec shocks.
My impression ? AWESOME for now

foxriderar77

anyone play around with the spring perches? I have the eibach sports on my MT car and even with the isolators removed I want to go lower. I know I should just buy the races but I like the idea of adjustability

Chad05TL

Why did you own so many TL's? I have actually been looking at a few Type-S' These cars will last as long as you want. I see many with over 200k.. I saw 1 in the salvage with 309k with a bashed in door and it probably would have kept on going. If I got a TypeS, I would probably transfer the knuckle from my base TL because I have a new ball joint and bearing in it.. And whatever else I could transpose.. Like my New headlights I got from Acura. They still look new. haha

Wow. If I can keep my baby, I am looking for higher quality coilovers then Tein. KW ? More comfort with handling. ? I have had many diff set-up. Looked for quite a while. Also going to have front painted- salt & pepper. Not to keep about a clear Bra ? Happy New year. Also Need a set of OEM HID's. $40 a set here.

I find this whole thread discombobulated...

Chad05TL

I think all coilovers will be harsh over bumps. The springs on those are short and firm. So you're going to feel it.
I have some Type_S springs for automatic, and I am thinking aout cutting off 1/2 of the bottom loop. Maybe up to 60% of the bottom loop. I should get a 1/2" drop according to the video's I have seen. And still be using the Tpye-S OEM spring. So, eh, not bad, it should be comfy. Like an A-spec spring, which you cant hardly find now... I have eibachs now and the front is too low for my liking.. So, just thinking about installing those cut OEM springs on the front only and leaving the rear. But I have no done anything yet. No pressure to hit it ..

Chad05TL

If you look on Tien's website, all their coilovers have like DOUBLE the spring rate as their lowering springs.. So unless you can find a coilover that has a similar spring rate of the lowering springs, then I wouldn't get any brand coilovers. I think they are all similar. They increase the spring rate for Extreme lowering. And that's not what I want to do. So, the coilover doesn't work for me because it introduces too much noise. And I don't want it that low anyway. haha
