2001 Carrera 4 Upgrade

Wheels and Tires

Vehicle Information: Year: 2001; Body Type: Coupe; Total Mileage: 5900;

I have a 2001 Carrera 4 with 18" sport designwheels, 030 sport suspension, and aero kit.The car is terrific, but some features of thenewer C4S are intriguing. The increased gripfrom the larger rear tires (295/30 ZR18 insteadof 265/35 ZR18) and greater braking capabilityare attractive for drivers ed events. Is itfeasible to upgrade my C4 to C4S specs in thesetwo areas? What would be required? Would I need tochange my current wheels(7.5f, 10r) to the C4S'8f, 10r? What risk is there of upsetting the handling or braking balance of the car with thesemodifications, or confusing the PSM/ABS systems?
