What's the difference between "standard" and "bulge" conical?? I cannot see any difference in the photos online at summit racing! And I cannot google up any page explaining either yet.

I need to get a 19mm key + small diameter setup to replace the 13/16 ones they jammed onto my Enkei RPF1s.

edit: well all the ones that I drilled down to using their selection system are standard, so I guess it doesn't matter at this point...
