Description Reviews Here is a set of MINI Head Bolts that will fit every make and model MINI Cooper or MINI Cooper S in the Gen 2 lineup (R55,R56,R57,R58,R59,R60,R61). These bolts are stretch to yield and need to be replaced any time you have the head off. This seat by Victor Reinz works just like the factory but you save a few dollars! They will fit all N12, N14, N16, & N18 motors. If you need something that can handle more power, look at the ARP head studs. We can also outfit you with any other gaskets and any other items you might need!
