Thanks Nick, there is a dearth of information here in the States about both the Cosworth and the Sapphire since we did not get either one.
The seller is even a little confused. He said the parts are from a Cosworth Sapphire, but also says the calipers are four pots. I'm under the impression that the Sapphire had single piston front calipers, correct?
I will have to check out the part numbers on the pieces once I get them.
Also, just to be clear, is the consensus that the Sapphire ARB increases caster when put into a 3-door?
TIA,
David L.
