I've been running my track set up - ARC8 18x8.5/255/40/18 MPSS - for 2 weeks on the street now since missing COTA due to pads that didn't fit and have loved the feel.

So much less understeer and tons more front grip, car used to really push badly in corners. Still does a little, but square is so much better than staggered.

Also zero rubbing, even on high speed corners on SH45 with a lot of bumps and road undulations. My only gripe is the TPMS light being on all the time, but have gotten used to it

Right so 18x9 ET 31 shouldn't need a 5mm spacer, correct?

Definitely not...you should have a good 10mm+ of clearance to the strut. You'll be very close to the fender though.

I am looking at the ARC-8 ET42 square setup. For those of you running these wheels, did it clear up the understeer issues on track or are you also running camber plates? I am looking at the Vorschlag plates but am concerned about the noise for daily driving.

I use the 18x8.5 ET38 with 255/40/18 MPSS square setup. No camber plates. Stock Sport suspension (RWD).

It reduces understeer a bit by providing a bit more front end grip but I would not say it clears understeer up.

Our recommended square fitment the F30 is:

F&R: 18x8.5 et35/et38 - 235/40/18
F&R: 18x9 et42 - 245/40/18

Hi, can you give recommendation for staggered set up on 19" wheels, 8.5F-9.5R? I'd like to get my car lowered that the fender lip is level with the upper side of the tyre, and I'd like to ensure there's no rubbing. I got KW DDC coilovers on a 335 sdrive f30 now.

I was thinking either of the following:
- 235/35 front and 265/30 rear
- 245/35 front and 275/30 rear

I use it on street 80% and 20% for trackdays. I'm also ok with up to -1 camber setting.

Thanks in advance!

Absolutely! I'd recommend the 19" EC-7 since it has the best offsets available for the F3x:

Front: 19x8.5" ET35 with 235/35-19 tires
Rear: 19x9.5" ET43 with 265/30-19 tires
- Direct fit with no modifications required.

We also have a 19" ARC-8 setup available:

Front: 19x8.5" ET35 with 235/35-19 tires
Rear: 19x9.5" ET33 with 265/30-19 tires
- May need rolled rear fenders depending on tire brand to prevent rubbing during hard cornering.

Hope this helps!

Apex Apex Apex. Strong. Lightweight. Stylish. Economical.

Running 18x8.5 et38 SM-10 wheels with 245/40 RS4s. On 245/40 PS4s I had no rub and it was VERY flush. As soon as the RS4s were on I had some gnarly rubbing on the fender tab. I removed the tab and rolled the fenders slightly but still had rub (mostly on bumper cover), it wasn't until I had camber plates that I was able to eliminate it. Always plenty of strut clearance.

Thanks Dylan, really helpful...

I'm planning to slightly lower the suspension, ie the fender lip levels with the upper part of the tires (so you cant stick your finger in anymore). Do I need another modification to ensure no rubbing? I plan to purchase Advan Neova 08 tires.

Thanks again, super helpful!

You're very welcome! With the EC-7 setup using the 19x9.5" ET43 rear, you'll be good on to go on stock fenders even with lowered suspension. Only with the 19x9.5" ET33 ARC-8 would you have potential rubbing issues and need to roll the fenders. A light roll like what you've described should be enough, but we recommend always being prepared for a little trial and error when going with an offset this low on a 9.5" wide wheel.

What's the biggest rotor size plus 6 pot rotors (Brembo/AP R) can a SM10 18" rims clear?

Absolutely love your setup, mind asking if your car is xDrive?

Would love to see more pics!

I'm in a 2015 435i xdrive coupe and running square 18x9.5 et 35 Apex EC-7s wrapped in 265/35 pilot sport 4s. I'm lowered on Dinan lowering springs and there is zero rubbing and the fitment has slight poke. I track frequently and this setup is amazing. [IMG][/IMG]

265 squared, but stock camber?? what for??

[R1d3r]

Can I bump this thread?
I need some up-to-date advice for a good square setup for a track day 😬I was running my street setup (235/35/19 and 275/30/19) with Conti 7, but I’d like to try 18 inch semi-slick square setup.

[E90lova]

I run Bimmerworld TA5R 18x9.5 35offset wheels 3mm spacer in front with 265-35-18 tires all 4 corners no rubbing.

255/40-18s on square 18x9 et30 rims are popular around here.
