2 w drive disc's plus brackets off Clint Gaskin (turbo sport £40) and keep your S2 calipers/ more power than 4X4 set up as the calipers sit right on the edge of the dics thereby more braking effort/use money saved to buy goodridges and (if you've got it) junk the whole 'abs' system.......then when you've got a bit more dough.
Brackets off Tony Pastie (zetec turbo £40) scorpio calipers and slider brackets off breaker (£25)(or new about £130) new discs Scorpio (£35 any motor factor) new pads (£25) M5 RS2000 handbrake cable (£30) break fluid
