i dunno how much longer than stock you want, but i found that my proton ones are 10mm longer than the TR magna ones and that my99 wrx ones are shorter and different thread.
i imagine you want to run wheel spacers
i reckon if you look at 4wd ones, they will be longer again as they would need a thicker hub flange and prob thicker discs too, maybe pajero? landcruiser?
