LSD is huge. Unless OP turns no corners.

is expensive, but yields a delightful daily driver and track performer. Do in stages if you wish - LSD before rear M sway, please!
Remarkably smooth handling with unending grip, 2.5° camber, if you can tolerate tire life. You should learn how to do precision alignments! Equip available from racing sites - highly recommended - you may want diff setup for street than track. Camber plates a great blessing.
