Hey guy I just purchased Forgestar F14's from d-townhakuzo's part out thread. The specs on the wheel are 19x8.5 +26f /19x9 +20r as he posted. I did clarify with him before I made the purchase that the wheels would clear brembos, he stated that they would. The wheels came via UPS today in great condition as he stated with all that he said he would included (lugs/spacers etc). My issues is that the wheels DO NOT CLEAR THE BREMBOS!

Granted, I should have done more research on my end to be sure they would clear but he clearly stated that they would so I trusted his knowledge. I need some help/advice on how to get these to clear. I tried using 5mm spacers that were included in the purchase (he used them on his rears) but that was not enough to clear. What options do I have beside purchase 2 new Forgestar's that clear brembos

get wider spacers lol how much more room is needed before you think it would clear?

TL-Sexi07

yeah I figured i needed a bigger spacer possibly 10mm? Extended studs are needed as well I'm assuming? Any recommended brands?

jwr0ng626

will an extra 5 mm be enough to clear the brakes?
I don't have spacers so don't know which is "better"..
your possible options are ichiba, akata, or H&R

TL-Sexi07

I tried 5mm but it wasn't enough. I doubled it up with (2) 5mm's and I think that will do it but the OEM studs will not work with 10mm's. I believe Eibach has a kit that comes with extended studs and a 10mm spacer...just can't seem to find it

heres ichiba 10mm w/ extended studs: here

or akata with the studs attached: here

When you attempt to mount the front wheel, at the point the spokes hit the caliper, measure the distance from the wheel backpad to the hub of the rotor. You should probably get someone to do the measuring but with a 10mm spacer you should be able to clear.

19x8.5 +16 isn't so bad really, make sure you have a 215/35-19 tire.

TL-Sexi07

The tires now are currently 235/35-19, do you think this will be an issue with 10mm spacers?

Silver_Surfer

If he sold it to you by stating that they would definitely clear the brembos then he pulled a fast one on you, intentional or not. I would take it up with the seller and ask for a refund or extra money to buy new spacers for your front.

FWIW I have F14 19x9 +25 and it clears my front brembos. Good luck.

TL-Sexi07

I agree. He has refunded me enough money to cover for the spacer kit. 10mm should be enough to clear the brembos, I'm just worried about the 235/35 tire being too wide for the front fenders...

TL-Sexi07, do me a favor and actually check the back of the wheel for the offset. It should be stamped on there.


Now read this thread where d-townhakuzo lists his offsets as +35F and +30 rear! Also the pics of his car don't look as flush as +26/+20 would. I'm wondering if he was arriving at the lower offsets by adding the width of his spacers.

Could you do me a HUGE favor and try to get an accurate measurement on how much clearance you have?

I just ordered 18x8.5 F14 +33 F, +28 rear after Forgestar assured me they'd clear the Brembos. I need to act quickly since it appears they won't.

Thanks!

TL-Sexi07

There are no sticker or labels displaying the size. Here is an image of the back side of the rim.

I took a look at the thread you posted and I see where he posted the +35F/+30R offset. I have never seen this thread until now! He clearly states different offsets in his part out thread...

Can you try getting a measurement from the recessed area with the letters and numbers to the top of the area that protrudes (part with the lug holes). Looks like there's a slight taper there, so your best bet to get an accurate measurement is to rest a ruler over the very edge and then measure up to the ruler from the outside edge. If you have something that measures metric, you can get a pretty close reading if you measure several times. I don't think you'll be anywhere close to 24mm, which is more or less one inch, which is what a +26 wheel would be.

(The max offset for that wheel is +50, so subtract your measurement from that to arrive at the actual offset.)

For visual reference, here's a picture of an 18x8.5 +46. It's odd he clears his calipers, which I believe are Brembos.

Yours appears to be a little more aggressive, but it's tough to tell from the dark picture.

aiya...

it's odd. I would think that even at 19x8.5 +35 the wheels would clear the brembos given that the before mentioned specs have 4mm more inner clearance and 16mm more outer clearance than the stock type-s wheels Forgestar also claims to have amazing clearance abilities on all their wheels (they also assured me that my 18x9 +29 wheels would fit) and they even boast being the only wheel manufacturer to have 18" wheels clear the GTR brakes on the Forgestar blog.

I wish I could help you all right now, but i'm at my apartment 40 miles away from my home where the wheels are at right now and I'm not going to go back there until this coming Sunday unless someone pays me to ship my rims to them lol gas is getting expensive!

anx1300c, remind me to do a test fit of the wheels on Sunday for you. I hope it won't be too late by then

This guy right here has 19x8.5 +40 on a base TL:
https://acurazine.com/forums/3g-tl-photograph-gallery-96/wdp-black-rims-f14s-non-iphone-pics-831665/

anybody know the difference in offset needed to clear the brembos over the base calipers?
and wtf why did he get 5x120? O_O

anx1300c

iTrader: (2)

Thanks, man! I may just call tomorrow and switch to +29 all around.

This is odd though. That wheel really looks like a low 40's offset to me. Definitely not a +26, as that would have close to a full inch of pad material since max offset in the 19x8.5 is +48, (I screwed up earlier, max is +50 only on the 18x8.5) and not even close to a +35 either.

and it's hard to eyeball the offset of the wheels from dtown's car because he's lowered and I don't know what kind of camber he is running, but even at the middle of the hub bore height those wheels seem to be quite sunken in. I can't say anything for sure though; the closest thing we have to judge by is jnoone's WDP TL because the wheels have the same dimensions, except we know his offset is +40. Anybody know the difference in clearance needed between base calipers and the brembos?

Not sure if it'll help, but here's sharksbreath's car with 19x9 +25 up front:

Since you're calling to change the offsets to +29, just cancel the order and i'll send you my wheels instead

Dude if yours were 8.5, glossy GM, they'd already be on my car. I'm only dropped 1.5", so I don't think I can really pull off even a mild stretch with a 235 on a 9, even though I have the Koni perches to play with. When I started researching F14's a couple months ago, I was stoked to find ~18 lb, good looking wheels that were affordable. Then I stumbled onto the whole 1200-1500+ load rating and all the claims of them gaining weight made sense.

I'm all about the performance too, and switching from my porker Bridgestone RE-960's (29lbs in 245/45-17) to 235/40-18 Conti's (21lbs) and then shaving ~6lbs off the wheels would've been profound, but as it stands, mine will still probably come in around the 21lb mark. I think the 04-06 base stockies are 24.5, so a 3lb loss, plus the huge weight savings from the tires will still be noticeable.

anx,

I took a quick look and it's a very tight fit. There is literally about 1/8" clearance between brembo and wheel.

TL-Sexi07

Hey sry I havent been able to physically measure my wheels, I've been busy with work. I'm still waiting on my spacers before I can mount the fronts. Should be here by friday .

I did check with the seller of my wheels and he did confirm that he ordered the wheels in +26f and +20r. This is w/o spacers. I'm still pretty new when it comes fitting wheels, tires, offset etc but they guys above sound very knowledgeable.

anx1300c

iTrader: (2)

The plot thickens.

Thanks for checking SS.

Can you measure the pad height at some point? I need to act ASAP and change my order. I've got a call into Forgestar but haven't heard back from them. You're the only one with access to an 8.5, and I'm wondering if the lower concavity of the 8.5 impacts the minimum offset required to clear. I'll subtract your measurement from 50mm and then another 10mm from that number. I appreciate your help if you can.

TL-Sexi07

Yes I will try my best to have some measurement for you tomm!

anx1300c

iTrader: (2)

Thank you.

TL-Sexi07

anxc1300c, here's a better picture of the 19x8.5 rim. If I'm doing the measurements right, it's about 1/2 inch or so. Hope this helps...

That's a huge help! Max offset for that wheel is +48 so minus a half inch would put it at 35. I wonder if a +26 square set up will work then.

lumyeinjun

iTrader: (1)

Very interesting... if that's a +35 on an 8.5" wheel and adding a 5mm spacer wont clear the brembos, then +30 on an 8.5" wheel wont clear anx, ill perform the same measurements on my wheels when I get home on Saturday in addition to the testfit My offsets can serve as a baseline since we KNOW what my offsets are.

lumyeinjun

iTrader: (1)

And maybe its just the angle in the picture but it looks like the measuring tape is reading 3/4" to me :/ if possible, could we get a more precise measurement? Preferably in cm or mm to the nearest .10cm or 1mm? I wanna help anx get to the bottom of this!

anx1300c

iTrader: (2)

I think it's the camera angle. Look how the second and third inch look progressively elongated. Pad height looks to be about the same size as the diameter of the stud holes.

The more I think about it, I think the issue with these cars is the relatively small rotors at 12". A 12" rotor pushes the caliper a half inch closer to center bore than a 13", taking it away from the more open area of the wheel. Most cars with BBK run rotors larger than 12".

Looks like it's going to be close for you at +29, Randy. Might need a small spacer. Do they even make them in one or two mm??

TL-Sexi07

I took another look at the 19X8.5's today and did a measurement with a straight edge, then measured the straight edge. I got exactly 1/2 inch again. Hope this helps..

lumyeinjun

iTrader: (1)

Interesting, can you elaborate on the 12" VS 13" rotors? I don't know much about braking system geometry

And I don't know if they make spacers that small we know for certain that a 9" wide wheel with +25 works on the Brembos (Sharksbreath's setup); let's hope there's more than 4mm extra clearance for those Brembos! Then again, he's running an aftermarket rotor. Do you think that will play a role in fitment?

Thanks a lot man, hopefully this thread can serve future Forgestar owners well! Good work, team F14!

anx1300c

iTrader: (2)

Check these pics. See how the BMW caliper on the huge rotor is further away from the centerbore and closer to the outer wheel/tire? It takes the caliper away from where the spokes curve inward, keeping it in the roomier area of the wheel. Both wheels are 19".

i wish i could help you out, anx.

how long do you have before you have to make a decision? i may mount my f14's this weekend if i have time.

It's ok. Mark from Throwdown has an e-mail in to Forgestar, so just waiting to hear back from him.

I appreciate all your guys help!

Ahh now I see your point! That's an interesting observation... we wouldn't be able to run a 13" or larger rotor unless we use the RL calipers, correct? The type-s Brembo configuration only allows a 12" rotor whereas the RL caliper geometry allows for changing to different sized rotors? Correct me if i'm wrong, i'm far from an expert on the subject lol.

TL-Sexi07

I was able to get the 10mm spacers on last night and mounted the wheels. The clearance between rim and Brembo was verrrry minimal but thankfully it cleared. Hope this helps!

anx1300c

iTrader: (2)

Can you fit three credit cards between the wheel/caliper? That's about 2.5 mm. If you can, then a +26 should clear, which is the lowest offset they make in the 8.5 width.

Glad you're mounted up finally. How's the fender clearance?

SharksBreath

iTrader: (33)

^i mounted my wheels today, don.

I'll measure clearance tomorrow morning and post a pic.
