They are made in high tensile steel and are also surface treated making them extremely resistant indeed. Each stud is about 5 threads longer than an equivalent standard length stud therefore also making them perfect for certain tuning kits such as TS1, SS, RB etc. As is the norm for all CP products, the lads have been testing these now for over a year, in all manner of engine configurations from bog standard LIs through to race tuned SS225 motors and the results have been excellent. The pictures speak for themselves and the Casa Performance code is X6h. They cost Euro 18.00 for a set of 4 studs (about GBP £16 in real money) and can be purchased either directly from us (via Rimini Lambretta Centre), or through any Casa Performance dealer worldwide.
