Gen 3 Liberty B4 cam with the lightest rims
AFAIK. Thin multispoke Forged BBS 17s. I dont know they exact weight but with tyres they were much much lighter than my old 15s with tyres.
I got some of these on my own car. But they will not clear any subaru 4 pot calipers. But they will clear 2 pot 294mm and 2 pot 319mm gen 4 Liberty GT brakes.
