Why Upgrade?
Factory head bolts stretch and lose clamping force over time—especially in tuned or boosted applications. The SneedSpeed Head Stud Kit solves this with a race-tested, reusable stud system that ensures consistent pressure, reliable sealing, and long engine life.

High-Performance Head Stud Kit for MINI Cooper Turbo Engines
Upgrade your MINI’s engine with the SneedSpeed Mini Cooper Cylinder Head Stud Kit—a premium bolt-on solution for serious performance builds. Designed specifically for Mini Cooper S and JCW models (R52, R53) with the W11 engine, this head stud kit delivers maximum clamping force, precision, and durability to prevent head gasket failures under boost or extreme heat.
Whether you're building a high-boost street car or a full track monster, this kit is engineered to handle the stress. Unlike OEM torque-to-yield bolts, SneedSpeed’s high-strength head studs are reusable, provide more accurate torque values, and ensure long-lasting head sealing integrity.
