Lets see that race again with a 335i wit a race map/race fuel. Then you can pull facts out of your ass.
Lmfao at the RDsport chip
who runs that on their car?
Slap a JB3 or V3 wit race fuel and then you can see the M3 way way way back.
To the OP, do your math and lets see the money spent on both cars as far as performance mods. 990 for a chip on an M3?
You can get a used JB3/V3 for 500-900$ You can spend 5k$ on an m3 and 335i, and I'll be the first to tell you the M3 wouldnt stand a chance on a straight line. The track is a different story.
