For reference:
Front's are 18x10 +30 (-2.2* camber)
Rear's are 18x11 +18 (-1.8* camber)
295/40's on all 4 in this picture.
IMHO Syno, get the same Enkei 18x10.5 +15 wheels the Z1 PWC race car is using along with a set of spacers and extended studs for the rear and call it a day. This will also give you plenty of wheel to throw even more rubber on down the road if you want. (315's
