Lower it better as the rear arch standard is lower the the front so... lower the car more and make the front lower than the back, put a bigger exhaust tip on that doesnt make the car loud, then do the mirrors, center of the roof and the spoiler in black then do the fuel cap white. To make the car look tidier and debadge the boot.
Oh and maybe a black lip spoiler for the front.
Just some ideas
