It will fit with coilovers. Did you read through this thread? It contains all the info you are looking for. (most of it in the first post)

I read but most of what I read it says they're on springs not coilovers. So if i go lower than spring drop which like what 1.5 inches. Will I rub? Basically what im concerned

Here it is...
Meaty Tire Thread
Because i have no idea where my original thread went i figured i start a thread
for ALL BRZ/FRS's that run meaty tire size. anything 255+ would be considered meaty for these purposes, everything else is just "normal" tire size.

just a few things that get asked ALL the time in here:

1) Most of us run a coilover, you really won't fit a 9.5 wheel up front with stock struts and will have minimal clearance with a 245 tire on a 9 inch wide rim with a 40-ish offset.

2) not all suspensions are created equal and not all cars are created equal. if something works on someones car, that doesn't mean it will be identical on yours, generally its true but not always applicable.

3) LCA are needed to adjust rear camber unless you don't care to correct it, you may also need toe arms or more toe adjustment via a bushing depending on your vehicle.

4) rolling and slightly pulling your fenders will give you more clearance than you think

please post up you modifications, any fitment tips, and obviously
feel free to use this is a photo dump for others to get ideas. if i need to edit something in the OP just lmk.


and now here is what i went through with my BRZ.

brought to you by @AZP Installs give them a shout
if you need anything, ESPECIALLY alignments, suspension work and track prep.


wheel/tires combo's i've fitted.

18x9.5 +40 Rays Gramlights 57xtreme w/ 265/35 RE-11 tire

18x9.5 +40 Rays Gramlights 57getter w/ 265/35 MPSS tire


Current suspension:
RCE t2 coilover
Group-n top hats front
GR STi rear tophats
SPC camber bolt
SPC rear control arms
Whiteline adjustable toe arms

perviously on AST 4150 and KW V3 and in pictures with xtreme's)

PARTS I DO NO RECOMMEND:
CUSCO rear LCA (PITA to adjust, if you don't do your own alignment then disregard and pay in labor)
WHITELINE COM C tophats (bearing failed 3 times)

YOU WILL RUB at first. its the plastic part of the rear bumper,
its not a big deal and will rub itself out of you can dremel it. (the corner to the bumper inside the fender)

Second I had an issue with my passenger fender, it rubbed on the part closest to the sidemarkers.
if you feel the fender there, it flares out towards the side marker, you want to roll that part in
to avoid any issues in the future or else you risk chipping the paint or gashing the tire....i luckily caught it early.

Third, and probaby most important. once we let the KW's settle we had to take camber out.
it settled to around -3.5' in the rear at the heigh i'm at. i did not want to run that much at
all, nor do i need that much for clearance issues. once it settle i fixed the camber with the
control arms however the STOCK toe arms did not cut it with the Cusco arms..so i upgraded to whitelines

My alignment specs are as follows:

camber F/R= -1.8/1.6 (-2.7 f/-1.8 rear for track)
front toe out= .08
Rear toe in= .08

car drives like a dream.

Right. None of there says +38 offset in 255/35 tire. Nor does it say how much drop he has. So my question stands.

A 9.5" +38 wheel will bring the wheel 4,3mm closer to the strut than a 9" +40 wheel. Ad a wider tire to that and the answer to your question is no, it won't fit with stock struts.

You're talking about a 2mm difference in offset, and a 10mm difference (roughly) in tire size.

If Jive's setup rubs at the height he is (look at pictures and you'll see its a good 1" to 1.5" lower), you most likely will too. Of course, you can always just run more camber to keep from that happening, but that's on you.

The answers are here in this thread. Multiple times, in fact. A little searching a reasonable (or common) sense would be enough to quickly answer your question.

Wrong. a +38 will push the wheel 2mm out (away from the strut) compared to a +40.

I can't do all the work for you. Turn to page one and give this thread a few minutes. I have read the whole thing. Everything is explained in detail. Many questions asked, just like yours, with answers. Also, I already told you it will fit with coilovers.

Not compared to a 9" +40 that jive mentioned barely fit with stock struts. That extra 0.5 inch in wheel width will bring it closer to the struts.
