Perhaps, but if you really want a dedicated race car then an M3 is a subpar platform for that. It's quite expensive, and for all that cost it's still underpowered, overweight, and requires a long laundry list of mods before being ready for racing. It's not a particularly fast car for the money either. For such a price tag there are many platforms that are more suited for building a race car, for example a slightly used C6 Z06, Cayman R, GTR, or even a Boss 302.
