Dedicated wheels for track use
Been thinking about getting some Apex wheels for the CS and track duty with some Hoosier slicks on them.
What sizes does everyone run? The car is at stock ride height and no plans to lower. Squared set up would be ideal. Is there anyway around the TPMS with BMW? Last track session I got them too low and it put me in limp mode essentially until I inflated them back up. I'm guessing there's a way around this? Would be nice not needing to order TPMS for the Apex wheels too.

A lot of people just run without tpms. I don't think you need to do anything special.
My EC7's have tpms in them, but I generally set them at about 28psi cold. Can't really help ya on the fitment, but the folks at Apex should be able to hook you up with what you need. I run 18x10 ET35 square on my '18. But I have suspension/camber/spacers/etc. Obviously for the CS, you'll need 19s. |

The mode limitations only come into play if you have tpms and it is reading lower than recommended pressures. |

I personally run without TPMS in my 2018. I get a warning message, but it does not affect my ability to run at pace on track. Once I dismiss the warning, I just get a flashing, and then solid warning light in the gauge cluster.
On my OEM wheels, I have just started the day at 30 PSI and bled off pressure throughout the day as needed. I’ve successfully avoided the low pressure warning, but you might have to add a couple PSI at lunch, or start a TPMS reset as you are staging up. Generally, you can get enough heat in the tires to bring the pressures up before the reset process completes. I’m happy with my Apex wheels, BTW. They have a very detailed figment guide on their website that should get you a good start on what fits. 9.5” ET28 is the no spacer square option they recommend. I ran a set with these specs for a year in 18” and was happy with it until a change to coilovers altered the handling of the car a bit, and I went back to staggered. There are other options if you’re okay with running spacers. |
