There's a guy who did a full m3 conversion, on a 325i...
What a total waste of money on a pathetically slow model.
I don't agree with all these people trying to make there 3 series look like a m3. As mentioned why spend all that money to turn it into a m3 body when that money can go towards one.
And second of all, even if you did spend all that money on the body, you still are left with the twin turbo engine, not a NA v8 master piece.
Not to mention the m3 diff, brakes, suspension, power button.
Put your pennies in a jar and save up because a 335i will never be a m3, faster maybe yes with RBs and full fbo and meth but not better IMO.
And I have a 335i ...
