S2's never came with rear discs. They can be converted, but trust me, they really aren't needed. The S2 is so light at the rear, that the factory drums are fine. If they can stop 350bhp from practically 170mph on a 2-mile runway, I think they are fine!!

Bazza's car is top notch for the money. He really is a bufty. We have done some work on it and from what we have seen, it's really nice.
