Actually all of those. When I bought the F1 GS D3's all 4 of them purchased, mounted, balanced, installed with tax and insurance came up to like 1700 if I remember correctly. I do NOT want to skimp on tires because they're the only thing in contact with the ground. But I don NOT want to keep forking over that kind of money being a wear item. Performance/lighter weight?? Sure I'll take that. Lowers the car a little, fine nice too. The car will be lowered to fill in the wheel wells as well.
