between the rs4 3 and the 4-tec, the 4-tec can't handle, i speak from experience, comparing hanling between the rs4 3 and th 4-tec, the 4-tec is FAR FAR FAR behind, sure the 4-tec is FAST AS HELL reaching speeds of 60mph+ but what the hell are you going to do with that speed if your car can't turn? just my 2 cents
