Wait till Stav is back from Tokyo and he will tell you what they are used on - ie some the fastest uk drag cars etc...

and at a few hundred quid, they look pretty bloody good!

of course people on here have used them and they have broke, so they can give 100% accurate info...

ok im lying, they havnt used them so of course say they are shite...
