ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
The M20 engine is a classic, but it is notorious for head gasket issues as it ages. The ARP 201-4305 Head Stud Kit is the ultimate solution for BMW E30 owners looking to ensure their 2.5L engine remains reliable for years to come. Whether you are doing a full rebuild or just replacing a head gasket, these studs provide a much stronger and more consistent clamping force than the original factory bolts.
By upgrading to ARP studs, you eliminate the risk of stretching factory bolts, which is a common cause of coolant leaks and compression loss in the M20 platform. These studs are designed to handle the rigors of both daily driving and track-day use, ensuring that your cylinder head stays perfectly seated regardless of engine temperature. The kit includes everything you need for a professional-grade installation. If you are restoring your E30 or building a high-performance M20, don't overlook the importance of high-quality fasteners. Trust the experts at GGCRACING to provide the best parts for your classic BMW build.
