Update by David S. Wallens to the BMW 335i Coupe project car
Feb 26, 2009

CCW recently borrowed our BMW to test some wheel fitments. The chassis can easily swallow something much bigger than stock.

We recently got an interesting call from our friends at Complete Custom Wheel: Could they borrow our BMW to check a fitment? CCW is located about 10 minutes away from our office, so of course we helped. The whole process took less than half an hour.

While there, Company President John Purner gave us some useful information. A larger footprint would definitely help our on-track performance, and he provided some particulars.

If we want to run 18-inch wheels, he’d recommend 18x9 fronts and 18x10.5 rears. He’d match those wheels with 245/40R18 and 275/35R18 tires, respectively. If opting for a 19-inch wheel helps regarding tire availability, then he’d go with 19x9 fronts and 19x10.5 rears; he’d wrap those with 245/35R19 and 285/30R19 tires.

So, are a set of CCW wheels in our future? Well, they are light, strong and attractive. We’ll see.

True, that exhaust is not stock.

I am not a fan of run flats and the resulting lack of a spare tire. Look forward to GRM's opinion on the run flats and/or the swap to conventional tires. i run a rim/tire combo from Tirerack for a spare in my E46 M3. Conventional tires but no spare as part of the M package. Had 2 flats in 2 weeks after the locals mowed the highways and slung debris on the road last Spring. BMW has bought in to the Run flats despite the unsprung weight, cost of replacement, etc. Have ya'll felt the side wall stiffness on those tires? It is insane. Curious how GRM will handle this. Plus one on the run flats could be brutal on the ride compliance.
Keep us posted on the Oil Temp issues. Those twin turbos will cook that oil.
Enjoy the magazine and hope to see you at the Mitty ........... BC.
