I am going to have the Acura dealer install them next week. I purchased these over the RSRs as they have a lower spring rate and are progressive. In H&Rs marketing as well they state they provide a like stock comfortable ride which I am hoping for.
Here is a pic:
I am also going to get these wheels in 20x10 et 40mm and 20x8.5 et 35mm. I am going to run 275/30/20 rear and 245/35/20 front. The tires I am going to run will either be Nitto Motive, Nitto Invo, or Continental DWS as they are a lot cheaper than most other decent tires and are supposed to provide smooth quiet rides while giving good performance.
I also bought a set I will have installed in a week. I called H&R two weeks ago and asked if the will be a specific application for the AWD. He told me to call back in about 4-6 weeks to know for sure. He said they were about finished testing for AWD. He didn't want to say for sure but it was looking like it would NOT be a different part but the same. I was suspecting this when the RSR application is the same all across he board (4, V6 FWD and AWD). Also in another post someone thought in previous generation of the TL it was different from the Type-S. 09-14 on H&R website only has an application for the SH-AWD TL. 04-08 was two separate applications for the TL vs TL type-S. The part 51846 is the same for (6 cyl Accord 13-15, TLX 4cyl, V6, FWD) this was good enough for me to buy a set.

Well mine is FWD so H&R actually has a part number. Apparently they ride a little more compliant than the RSRs as the rates are lower and they do seem like they will be good as you can literally compress them with just your hand on the "dead coil" portion. This makes me believe the first part of the progressive action will be a good ride.
How low is the drop on these H&Rs? I like the conservative on the RSRs and don't mind the stiffer ride quality. The stock springs feel like I'm in a boat currently :p
Well if you go to their website....no being rude just saying . It says 1.3 Front and 1.2 rear. So it is about the same as RSR being 1.1 and 1.0
100% honesty, no offence taken, I was just being lazy haha Thanks for your response though Looking forward to seeing your updated car with drop and wheels.
I am getting the springs installed today at my Acura Dealer, they are charging me $600 to install and do alignment, which in my opinion is a relative screwing, but if I have any problems at least I have big reputable Acura dealer to honor their work.
The ride is not bad at all. A bit firmer than stock, but not harsh. I still do have the factory 17" wheels however so I am sure it will stiffen more when I put my 20s on next week. If definitely hugs turns a lot better. The all wheel steering is awesome now that its lowered it just graps through the turns.
The springs are progressive so the smaller bumps are well absorbed, but when you hit abrupt bumps like construction elevation changes where you run over like a 1-2" dropoff or step up are firm, but not bad. I am used to running coilers on my past vehicles, but wanted to save some coils as this is a lease. I would say a nice set of coilovers would ride a bit better, but not $1500 better.
The drop looks decent so far, we'll see how it looks with my 20s wheels on it next week sometime.

Measured from floor to bottom of fender lip through center of wheel and the rear measured 27 1/4 inches and the front measured 27 1/8 inches. I think the rear measured a smidge higher as the camber lifted the rear with the tire tilting in and that is your 1/8" difference from front to rear. Once I get an alignment it should be dead level.
Looking good! I have the same impression regarding bumps with my springs. The concrete streets around where I works are falling apart and lots of cracks, pot holes, bad repairs, etc. I wish I could get a smoother ride and still have the lowered look. I love the stance the car has with the wheels and perfect (IMO) offset with the rims but the ride tends to be much harsher than I'd prefer....

Sacrifices must be made!
Anyway, keep us informed on progress.
I am pretty sure the H&Rs ride a bit softer than the RSRs do as the spring rates are less and the H&Rs have a lot of "dead coils" and "soft coils" to absorb the small stuff better.
thanks for the response pictures Sincity! I cant wait to see the 20s. I also ran coils on my g35 but im not planning to go as low so springs is the best bet.
I got my eyes on the niche surge 20x8.5 +35 and 20x10.5 +45 I just hope the H&R dont go too low and ill clear. Keep us posted. This helped thread helped me a lot.

Well I am going put on 20x10 et 40mm and 20x8.5 et 35mm with 275/30/20 rear and 245/35/20 front tires. I have done A LOT of research and this should be fine, I know the 10x5 et 45mm will be fine as well as there are about 2 dozen people with this setup and no complaints. Hell one of them even has 285/30 rears and no rub, but he is at stock height.
Yea im going to run the same tires on mines set up. Yea i been tryna search all over Forums,instagram and everything lol. Btw how much did the dealer charge you to install the springs?
They bent me over, but I accepted as I knew I'd have my warranty and if I ever had any issue they couldn't blame it on the installer. They did it, they own it )
They charged me $600 which included an alignment which I have not done yet.

I wish I could try these side by side. I'd be tempted to switch if I got a smoother ride.
Looks good. Like the drop. waiting for H&R to confirm this works for the AWD as well (spring rate), then I might be getting these.
Call excellerate performance, they are a site vendor and that is where I ordered mine from. They will tell you rates and are knowledgable about their products. They advised me to get H&R over RSR because they are a smoother ride.
Ride looks awesome sincity!! Love the drop, and I'm glad it's a quality ride. We have these same springs as a confirmed fitment for the SH-AWD. I can't comment on how exactly their performance will change being on the SH-AWD. It would be great if someone who has one and installs these could leave a review!

Probably even better as it is a heavier car. So it may ride even softer, but a smidge lower.
I have the SH-AWD and a set of these gambling it was a same fitment. The Acura dealership I got my car from refuses to do. The other quoted me $800 without alignment. I have a friend who is a Mazda dealership mechanic who is willing to do it for $550 with alignment. Hopefully this weekend. I keep you updated.
After a couple hundred miles of driving the springs seem to have settled all the way, the past several drives I went over some bad roads and the measurements have stayed exactly the same.....27 1/8 inches front and 27 1/4 inches rear.
The springs ride very well, however you can feel when the run out of travel and shock bottoms out on the bump stop. I hope Koni comes out with some replacements soon as the stock shocks are very mediocre. The springs themselves though ride great and are riding better each time I drive.
Installed H&R part 51846 on 2015 white TLX SH-AWD tech.
Before with stock Eagle Ls2
Then installed with Michelin Pilot AS/3 V rated 225/50/18
I installed the tires about a week before. Things I noticed about the tires:
A smidgen more road noise.
More road feel in a good way.
Much better grip. I had a few corners I liked to slide around. Now the tires just grip.
Rim guard so no worries about gashing rim against curbs.
After H&R spring install with stock shocks and front bump stops cut 0.75" per manufacturer
Amazing control
No more squat on acceleration or dive on braking. I didn't realize the stock springs did that until after I felt the difference.
Before if I swerved across three lines of traffic it felt kinda scary at 70-80. Now it feels in total control.
Much more road feel. I can feel the bumps but not harsh or jolting at all. I have gone over train tracks and varing road conditions. Every once in a while when going into parking lots or large speed bumps the back will thud as if it bottomed out or is it fully rebounded? It is not annoying to me though. I don't feel that in the front just in back. To compare I rented a car a few weeks ago on vacation where I rented a 2014 civic and I felt the bumps, clunks and thuds from that suspension more so. At freeway speeds it does rebound faster up and down so even it can perceived as more bounce (not multiple bounciness just a single controlled quick rebound) then a cloud with the stock springs. I don't do a lot of long distance freeway driving so it is undetermined if that would be annoying or not. I think the more I get use to it I probably won't notice it as much. When flying around a 90 degree turn it is pure joy!
1-1.5 finger gap between tire and fender, depending on how fat one's finger is. Approximately 3/4inch gap front and 1 inch gap back.
26.5 inch from ground to finder in the middle of tire front
26.875 inch the rear
5.625 inch from ground to center of stock side skirt.
I have to be modifyhow quick I drive up and down ramps or parking lots so as not to scrap
Unfortunately I forgot to do measurements before my friend installed these. Whoops.

Reason: Swap image
You mentioned the camber was a bit off. Do you have the camber specs ?
No I don't. The rear looks kind of like a BMW X5. It's not bad, but you can notice they are tilted a bit. It does seem to grip better in the turns now though so I like it.
What do you mean "cut up". Wouldn't you just swap the top hat and rubber.
From what I've seen in the past with macpherson struts, Koni does not make the factory attachment points for the front. We had to cut up the stock shocks and insert the Koni yellows.
These springs look great. Can you take some more pictures once they have settled?
Also how'd the alignment specs turn out?
Also curious to hear more feedback on the highway ride quality. I've had bouncy springs before and I never want to have them again as driving on the highway was miserable. I'm ok with them being firmer on larger bumps (which is kind of unavoidable) but bounce is something I cannot live with.

I am a picky dude and have always had coilovers due to the ride being superior to springs. These springs ride great though and are by no means bouncy. The rebound on the stock shocks is a bit soft, but for the price they ride phenomenal. And this coming from a guy who had ridden on coilovers such as KW and Ohlins which are world class suspension systems. Not to say the H&R springs are as good as, but they certainly are the best option for the price.
And they have settled all the way. Check my threads posting my new wheels being installed.

Thanks for your response though 
Looking forward to seeing your updated car with drop and wheels.
