I have it nailed down to the team dynamic motorsport or OZ F1 racing cup rims. The TD are cheaper. What is the weight of these wheels and how much more do they weigh than stock?? Will I noticed a performance loss if I go up to 18" size from ym stock 16" SVT rims?? What about rubbing??? I know they come in 18x8 size, will that rub??? The car is not lowered and might be down the road.
