Hi Steffan,
What is it you need exactly - a new rear caliper and master cylinder (SZR) are about £60. I have a caliper and m/c you're welcome to but the seals in both are suspect. I also have a braided rear hose that you can have for postage but suspect you're looking for the caliper carrier or somesuch? Does the Skorp run Brembo brakes as standard?
