Raceware is not making headstuds for WBX anymore. I suppose Okrasa ones are not available either? What other alternatives there is? I cannot use M14 case savers and T1 studs, since there's not enough space between the head stud and cylinder hole.
the stock studs are able to cope with plus 400 hp, as proven on this thread. as you can see from the pics above, ive chosen to use them in my turbo re build, if i was worried about they're integrity, i would have used the okrasa studs in it. hope this helps...
