So the PCFs squeal during DD? I plant keep mine in once track season starts. Fortunately mine is not a DD.
Also curious what tire combo you run, what you tried and how you landed on this configuration.
Thanks. |
I struggled mightily to come up with my track wheel and tire combination. I'm running a staggered setup since it was the only way to maintain the correct tire height which differs front and rear on this car - 25.7"and 26.0 (as far as I recall). This maintains the proper revs per mile of the tires front and rear. I also wanted to keep clearance issues out of the picture since I have no interest in adding camber plates or wheel spacers. I really wanted a square setup but I could not get there given the front and rear OEM tire height diff. As far as going with 18" wheels, first, they are lighter and cheaper. The same goes for 18" tires since they are also cheaper for track duty. Last, the Hankooks have super stiff sidewalls, so they don't rollover like the OEM street tires.
I had prior experience with the excellent Hankook RS-3s on a prior car, so I felt ok going with the RS-4s. The only real downside is you can't rotate them on the fly front to rear and side to side, but mid season you can flip them and remount them to get max use out of the tires. Last, I used close to OEM wheel offsets front and rear - ET 30 front and ET40 rear.
Finally the wheel width differs by 1" front and rear. All in it was a great decision since the OEM M2 is far more neutral compared to my old M235i which had a lot more front end push - ie understeer.
I'm very happy with this easy peasy setup. Swapping pads and wheels now only takes me 40 minutes since I learned to jack up the one entire side of the car at a time making pad and tire changes super efficient.
Tires are 245/40-18 and 265/40-18. |
That's very helpful thanks. How are the RS4's across different driving conditions? (Hot, cold, damp, dry etc)
If a stiff sidewall tire helps negate the need for camber plates that is good news.
I believe you can run a 265 square setup with a TPMS reset and driving 70km before lapping without and stability control effects etc. Will need someone here to confirm though.
What wheels did you end up going with?
Cheers,

The Hankook RS-4 is very good in warm and hot weather. More than good once brought up to temp cool and damp conditions and and not as good as OEM in the wet. As I mentioned, wear rates on track are great and the tires don't rollover and in my view, they are relatively cheap compared to other tires. As far as wheels, nothing super special - RIAL P10 18x8 ET30 and 18x9 ET40.
