Can never go wrong with the classic silver setup. It always looks good regardless of the color of the car.
Matte black with a polished lip looks nice, but it's been done.
If you want something completely different, you're gonna have to take the risk and go bold. Black with an orange time attack style or even black with a green time attack style. A little subtle but noticeably different.
Here's mine with a few different sets over the years.
SSR Professor - matte black face with polished lip
Volk RE-30 in a gunmetal color. Forgot the exact color name
VMR's
ATF (all time favorite) BBS LM-R
