Not to try to engage in a discussion about who has a longer e-penis but tires are by far the biggest influence on a street car's performance. There is no other mod that even comes close to improving a street cars performance.
The subject of this thread was M5 vs. M6. Neither car is shabby on a track. If you choose, the M6 will be faster around a track. Also, this tangent started when people compared the M6 to other cars on a track. The M6 will not beat a Miata around a tight track but will more than hold its own against M3s and others.
