Head studs on air-cooled engines is about cylinder to head stability.
To build reliability and a stable platform for performance Supertec head studs offer the best all around clamping consistency that we've tested. We tested Raceware, ARP, Dilivar of every iterations and even a "Super Stud" sold as a Dilivar replacement by some of the wholesale outlets. The testing of course started with stock steel Porsche head stud and nothing even comes close to our design.
Add ease of assembly, unique design, unparallelled quality and a life time guarantee and Supertec stud heads are hard to beat.
And then there's the price that has remained consistent for 12 years.
