I mean you could always get more carbon Fiber(Edit:Unless thats Fiberglass already).. Hood,Trunk,Wide Body Fender's & M3 Mirror's which will also make it more sporty feeling with the loss of weight, I also like the flater look of the m3 Side moulding . A big brake kit makes it look great too Brembo, Willwood , ETC.. Other then that i like the clean look.
