18 Inch F for wider tire?
Just finished my first autocross season in the my 22 M4CX and thinking about a few changes during the off season. What I would really like first and foremost in more rubber under the car. Ran this season on 275/35-19 square RT 660s, and while they're good I'd always opt for more mechanical grip if possible.
I'm wondering if i go down to an 18 if id be able to fit some 295/30-18 A052s. considering it's 1.5 inches smaller in diameter, would that offset the 1.1 inches wider tread width?? Largest issue with wider tires seems to be rubbing on the fender liner and cooler vents at full lock. If anyone has any experience with this I'd greatly appreciate it!

Would be an illegal modification in street classes, so the answer is smaller diameter wheel. The non comps come on the 824Ms, so 18s will fit over the brakes. Was just wondering if anyone had tried it out yet.

Also are you looking to go 18 inch squared? As comp x drive was never speccd from the factory with the 18/19 split the rear 2 inch drop in diameter does not fit within the rules. If you are fast enough to worry about a contest from heatgunning fender liners you will most definitely be contested on the rear diameter drop. |
