This. This car isn't really set up for burnouts and such. A solid axle rear suspension pony car (e.g., Mustang) would be a lot better for this type of stuff but an M3 is much better around corners and on uneven surfaces. If you really care, there are ways of modifying your suspension that could get rid of the axle tramp (often different damping rates, addition of stabilizer links in the suspension, etc...) but then you're building a drag car.
