sparkin, I'm getting there now mate.
 Having picked up the genuine 851 sp single seat unit, chopping the subframe to fit the seat turned out to be a complete no-no.
 So Put the plan on hold for a while, luckily managed to get a genuine SP ally subframe (thanks to Rob ).
 all fitted now, just need to get some foam pads.
 The 6 pot AP Racing calipers and disks I stuck on are brill, a massive improvement over standard units.
 
 will get some pics up shortly.
 
 cheers
 robin
