lowered on KW V3's. Alignment settings are on the aggressive side, also track the car once in a while. Currently running 3.5 degrees camber up front and 2.5 in the back, so needed a 10mm spacers up front in

order to clear the front struts. Have minimal rubbing on the plastic fender liner/front bumper junction area. Tires are NT-01's up front, and Maxxis prototype race compound tires in the back, testing for the company.

Not sure how much camber I will need and how large the spacer's need to be..

I want to run 18x9.5" square on Hankook RS3's 265-35-18

If that requires far too much negative front camber then I can do 18x9" with the same tire

thoughts and or ideas?? things I should know.

I want to use these as a dedicated wheel and tire setup for the track.

It's working great! I can drive around pretending I'm a coupe, and when I get bored I can morph back into a roadster.

I pm'd paintpro and asked him, about what would be needed and if on a lowered car it would rub and if the fenders would have to be rolled. Hopefully we get a response.
I don't want to roll my fenders, and i want a square setup.

I don't mind the rolled fenders so much but the square setup is very important. Keep me in the loop for what you find out please!!

"The rear is easy. The front is the only side with concern. To run a 265 square setup, you would need camber plates installed, and run the camber around -3 degrees.

If this is a track setup, then 3 degrees negative or more is ideal anyway. This is basically the setup that 70% our E46 M3 customer run (265 square on the same wheel with front camber).

It makes for a very well balanced car with a lot of grip."

i believe its the 9.5 but i sent him a pm for all the info about spacers, rubbing on lowered suspension, wheel size and offset, and bbk friendly for the future.

To run 265's square, you will want to run the 18x9.5's, not 18x9's. The 18x9's are not the optimal wheel width for a 265, and they are the wrong offset front and rear to just bolt directly on the car.

The ARC-8 is available in two offsets. ET35 and ET22. The ET35 offset is perfect for the front on cars without a BBK. The ET22 is perfect for the rear. You could potentially run the 35's up front and the 22's in the rear, but then you can't rotate. You are better off running the ET35 wheel front and rear. A spacer is not required in the rear, many members are currently running that wheel/tire size in the rear on Z4m's without a spacer, but I would personally run a 12mm spacer in the rear to correct the offset. A lowered car will not have rear rubbing issues as both wheels are more conservative than the 18x10 that members run with the 275's.

The photo below is off a stock Z4M with 18x9.5" ET35 wheels in the rear and 265/35/18 starspecs mounted. You can see it fits fine, but technically there is room to run a more aggressive offset like the ET22.



If you are running a BBK up front like a stoptech 355, then because of the spoke concavity, there is only 0.5-1mm of clearance on the very edge of the caliper. A 3mm spacer would be recommended for spoke clearance. 3mm spacers will keep the car 100% hub-centric so there is zero downside to running them.

The photo below is of a Z4M with 265/35/18 pilot cups on an 18x9.5" ET35 wheel and negative camber dialed in. I do believe a 5mm spacer is being used in this photo up front, so if you don't have a BBK, then less camber is needed to keep the wheel under the fender. I don't know if the camber on this car was achieved with camber plates or shimming out the strut. Plates would be the best way.


I can see in this photo that the same sized rear wheel is used (et35), but I cannot tell if it's been spacer'ed out at all, as it appears to be more aggressive then the black car above. My guess is it has.


The final setup of wheel/tire size and camber settings is basically identical to what E46 M3 owners run as an optimal track setup. They have more front fender clearance, but if you don't run a decent amount of front camber you will be slow.

Camber plates are highly recommended for any car that sees more than 2-3 days of track use a year, and definitely if you have a dedicated set of track wheels, as that allows you to adjust your camber from street to track mode in just a few minutes.

you sir, are the greatest!!!!!! CANNOT WAIT to order a set!! Good to know I can do a bolt on square setup with 265 all the way around. The car will be clued now.

Thanks again!

I'd like to run 18x8.5 ET38 with 225-40R18 front and 18x9.5 ET35 with 255-35R18 rear on a non-M Z4 coupe. Will I have any problems with the offset? Also will I be able to add a bbk kit on the fronts?

FWIW, I ordered four 18x9.5 35 offset with 265/35 Star Specs for street/autocross on a Z4 M Coupe that is otherwise completely factory spec (original suspension, alignment). I installed wheel studs and 5mm spacers that I already owned (maybe 3mm would work) up front so the tire's inside rim protector would not brush the strut. I did not need spacers for the rears. 100 miles and an autocross so far and no problems. Waiting for suspension and camber plates.
