As official as it gets anyways. An M3 conversion executed on a e46 sedan and driven like every BMW should be...

Rear 1/4's from BMW to properly do the conversion, $500 each new:






















A little cut and paste for the fenders since they aren't direct swaps:

New suspension for the sedan:



and brakes:



Teaser:









Seats:



Modified spare tire well so the stock M3 exhaust would fit (M cars don't come with spare tires):





Work done on the CSL style trunk to line up the rest of the car:



After all that bodywork, still having fitment issues with an F1 wheel & tire lol!











Track wheels in:


Track tires in, used Porsche cup tires lol!





The owner/builder couldn't decide on a color so he had both front fenders painted in the choices they narrowed it down to: Space Grey or Le Mans Blue...



Space Grey?


or Le Man Blue?



He decides on Le Mans Blue...
