I am hearing more and more about cracking on these types of wheels, they look great and I have a set om my boxter. What causes the craking and can they be fixed and if so how do they fix the crack lines. Is the wheel unsafe to drive on with crack lines or is it just cosmetic. Any advise is appricated, I am bit concerned, I examined my wheels could not see any cracklines.

 

I've got the Formula too. When I get installed, the guy said that when it cracked, I should just get a new wheels. Its hard to fix the crack and I think it the problem will reoccur.

 

what causes this cracking?

 

don't know what the issue
