Hi, I am looking at buying a VX/VY clubsport or clubsport r8. I have been made aware that apart from cosmetic differences the R8 offers better brakes. I understand that the R8 has 4 pot calipers and slightly larger disk than the clubsport with 2 pot calipers. Can anybody advise whether the standard clubsport are good enough for spirited road use and how much better the R8 brake are?
