Hello mate.
Long time no hear

How are you getting on with your front BREMBOs on the CS ? All good I hope

Yes SORRY I was going to let you know about the rears but you are correct, I'm about to bolt my rears onto my CSL and as it happens I do have spare set of rear brackets (somewhere) for you

Despite being smaller then the fronts they cost slightly more to produce and you get extra nuts & bolts with them + the usual brake line connectors B-) £200 all in including "Special Delivery" for next day by 1pm is the price and the BREMBO callipers you need are the rears off BOXTER S/ CAYMAN S, part numbers 996.352.422 & 996.352.421. Makes it easy ordering replacement pads

for this set up as it's off one same car.
Let me know if you're interested

ATB
Matt
