However, 19x10et25 is an aggressive backspacing on the front especially with stock struts and stock barrel springs.

hey man, didn't mean any offense - not sure if you took it that way. you def had a ton of experience with diff setups and I can see that from your posts. I did look into running 359M squared for a bit before deciding to go for a different setup but here's some reference I found as far as 19x10 ET25 on relatively stock setups:

275/30/19 on 19x10 359M - entirely stock suspension
265/35/19 on 19x10 359M - judging by the date of the post, I think Malek's car was on H&R springs?
275/30/19 on 19x10 359M - H&R springs and camber pins pulled, but stock struts

edit: might have misinterpreted your original question, but I guess an answer we can agree on is that it does seem like running 275/30/19 in the front is viable with stock struts and springs or stock struts and lowering springs, providing that the tire used is something like an ECS/PS4S and not something with wider shoulders.

I did not. Genuinely was thanking you for pointing out my error. I’m used to running 285s on a 10” front and that leaves little room even with my JRZ RS1 and MCS 2WR setups with 6” main springs w/ helper springs on my e92 M3s. Also a 285 A052 or RE-71RS run wide and square.

Fair enough haha, front strut clearance is something I'm worried about going into my next setup. DM'd you with some questions if you don't mind!

you'll be fine with -2 camber pretty much stock top hat with the alignment pin removed.

Thanks. I've been reading up on this and I've read anywhere from -1.3 to -1.8 max with pins pulled. I know it's not a huge difference but .2 can be significant no? Curious the minimum required for above setup.

Personally, I’d run -2.5 deg of camber to better tuck the tire into the wheel well with a 10et22. -2.5 deg of camber is perfectly fine on the street if you’re running a little bit of front toe-in (total tie-in of 0.125”) or zero toe. Excessive toe is what causes accelerated tread wear.

A 0.2 deg delta around -1.5 to a max of ~-1.8 deg of camber isn’t going to change things much. A -0.5 to -1.0 deg is something you’d start to notice. Not interested in getting camber plates that work with stock springs and can be converted to linear race springs of 2.25”, 2.5” and 60 mm IDs?

The 19x9et15 has an outspacing of 3.909” which is virtually identical. I know I could run a more aggressive offset than 9.5et22 and I believe I have more than 0.15” clearance to the fender liner. I’m pretty confident I could fit a 245/40-18 on a 9et15. If this doesn’t work than you can’t run a 19x10et20 (et25 I believe has a clearance issue with the inner strut/spring) with a 265/30-19 (unless the shorter sidewall clears?).

I read some post of rubbing in this forum. ET and tire size are really a jungle. Im thinking of buying a complete new set of JR SL-01 so i get right spec for my car. So a last advice for me?
If i choose a 19x9.5 front what ET and tire size would you go for? And for the rear a 19x10.5 wheel, what ET and tire size there?

Thanx again!

Personally, I’d run a 265-275 on the front 19x9.5et22. I’m running an identical wheel width and offset but in 18” with a 275/35-18 tire. If the 275-30-19 has a very similar rolling diameter of a 275/35-18 then you’ll have no rubbing issues.

For the rear, I’d run a 295/30-19 tire on a 19x10.5et25 which has a similar frontspacing as my 10et16 rear with a 285 tire. There’s more room to go a little more aggressive but then the front and rear outspacing will be very different.

Thanks so much for the advice

I’m running 275-30-19 fronts
Lowered and stock camber with out any rubbing

Looking for some insight here if anyone’s been trying out this set up….

Did a bunch of forum prowling but couldn’t get a concrete and consistent answer apart from theoreticals and the ole reliable “just run 18x10 and/or camber out”.

Has anyone ran 18x10.5 et25 on stock ZCP suspension with or without a 3-5mm spacer for clearance?

I’m in a position to acquire a squared set with 265/35 semi slicks and am trying to figure out if it’s something I can run for the remainder of the track season before considering coil overs / camber plates.

Thanks in advance!

This thread is pretty damn awesome and informative. Spent well over an hour just scrolling this post.

18x10.5 or 18x10? Just wanted to confirm because a 265 on a 10.5 is a bit stretched.

265 on a 10.5, it’s currently being ran on an f8x track mod car, I’d be switching over to 275 whenever the tires get spent

Sorry the pic of your quote didn’t load


This spec?

Yes! The one on the black e92. It is quite literally perfect. (I actually just got a jerez black car).

I don't know if the pictures aren't loading in the quotes due to me being new or being on my work computer.

Try uploading pictures using the paperclip, selecting the pictures you want, uploading them and then submitting your post. I believe you need a minimum of 10 posts and then 24-48 after your 10th post before being able to send PMs.

I assume you needed the spacer to clear the spring/strut? It looks very pokey lol. And based on that being an effective 11" +15, I'd think so, especially with only -2* camber.
