With so many BMW M3 tuning projects out there, it would be hard to point one out and say “this is the best one”.

Fact is, there are plenty out there that do a splendid job of either boosting performance or upgrading appearance, or even both.

This E46 BMW M3 does rather well on the performance front, with the visuals receiving only a bit fiddling. Apart from new Volk wheels and Bilstein lowering springs, nothing really gives it away. But turn the engine on, and you will find out that actually a lot of work went into the build.

From Active Autowerke, PSI installed the stage 2+ supercharger, giving the BMW M3 a power output of 520 Hp. To that, add a new AA methanol injection and a new fuel system, with the manifolds replaced in order to handle the extra pressure. The black paintjob does a good job of preparing you for the mad experience should you ever take the E46 BMW M3 out for a spin.
