Supertec studs have a longer 10x1.5 mm thread at the case end and a longer 10x1.25 mm thread at the nut end.
These longer threads make the stud very suitable for custom built engines that use non standard strokes. When building longer stroke or longer rod engine special stud lengths are desirable. Supertec studs offer this longer length and superior fit on stock engines.
The 12 point nuts offer a fitment for twin plug application that stock Porsche head nuts do not. When using stock head nuts and studs with twin plug there is a interference that must be remedied. Some people use a 6 point nut as a remedy.
No such interference exists with our stud & nut combination.
