Questions on running OE CSL/ZCP 19x9.5 et 27 squared on the e46 M3.

This looks so good, are you running a rear spacer at all?

Yeah 10mm in the rear with cut fenders. On my street car with stock fenders I run a 7.5mm spacer.

I have also run square CSLs with both TCK DA and Ohlins R&T with to clearance issues. I ran 265/30 on all 4 wheels. Also no issues up front with BBK or 996 Brembos. You do need at least 2-2.5 of camber for it to look right. Agree with post above that another solution would be to machine the backpads if you want less camber. I thought they looked pretty good as is:

I'm daily driving a square set of rear ZCP/CSL wheels with 265/30 on all corners (Firehawk Indy 500). I also have Stoptech ST40 front BBK (4 piston). I do not have any rubbing issues at full lock (parallel parking, tight U turns, etc). There is also plenty of front BBK clearance. My camber settings are -3 (front) and -2 (rear), and I also rolled the front fenders. No spacers up front, but I do have a 12.5mm in the rear. Hope this helps.

Can you post some pictures of the setup? I like how the fronts look with camber dialed in, but it seems like the rear is sunken in a bit by comparison without a spacer. Would love to see your setup.

Thanks! I have run Cups and PS4s with no issues. Also my Ohlins are a progressive spring. I haven't done much research on the back pads so not much to add there.

Did you swap them out to progressive springs? I thought the Ohlins came with linear springs? Even though they look like OEM progressive springs to mate with the stock top hats.

[robgill]

I believe the TCK DA and Ohlins R&T run linear springs. Do you think that running a progressive spring would cause issues running that 19x9.5 with 265/30/19?

Which tires were you running in 265/30/19? I would be looking at using Michelin PS4’s.

I thought about shaving the back pad but still need to perform more research to see if that is safe and possible.

Is the back pad thick on the 19x9.5 wheels? What about the lug hole seed is that area thick or thin?

Your car looks insanely nice and clean in those pics.

Not at all. Most that run 9.5 up front run et22. Csl 9.5 is et27, so it's an even easier fit. Neg camber is what's needed, and 265 tire not 275 tho that might just work too

My fenders have all been modified. Fronts are rolled, and rears have been professionally shaved. They look 100% OE from the outside, but they've been shaved and re-sealed (versus rolling).

So you would require front fender modification for it to work?

Yes that definitely helps. It’s looking like more and more that it would work especially with the camber up front. Question is would Michelin PS4’s pose a problem.

Maybe it's the wide Michelins. I've tried over -2.5, but then it causes more toe in and the rubbing is at the back of the fender, where the wheel flares out due to toe in. After an alignment, maybe I'll be able to run 10mm rub free. 5mm for now :/

Damn how did you fit a 12.5mm the rear Beau? Even my 10mm causes slight rubbing, at different camber settings. Could be my toe going in more with more neg camber that's causing the rubbing or maybe your rear fenders are pulled too?

I can clear a 15mm spacer in the rear. All about dat camber and toe bruh. -2.5 and 0 toe ftw.

I run a 12mm spacer in the rear as well with no rubbing. I do have camber arms in the rear and my fenders have ever so slightly been pulled.
