ARP makes some the best fasteners in the world. Their MINI Cooper head stud kit is all we use when we do head jobs or engine builds. From stock MINIs to our 450whp Super Coopers everyone of them gets ARP head studs because we know we will never have a problem with the head gasket not sealing even at 30 psi of boost!
The ARP stud kit is a direct fit stud set for the R53 MINI Cooper S. It comes with all the stud you'll need to fasten the head to the block. They are made from 8740 Chromoly steel, rated to over 200,000 psi, then heat treated, centerless ground and the threads are press rolled on making them 20 times stronger than competitors studs.
