has anyone ever figured out whats going on with the grooves inside the rear wheel? the only thing I could figure out is that when the suspension is fully compressed the lower a-arm is very close if not hitting causing the groove. has anyone found anything else out?

 

yea the nub on the bottom hits. some ppl file it down and then it doesnt . apparently the updated 525s dont have this problem

 

well thats about what i saw so guess ill try to cut it down before it takes out my wheels. aint like they are cheap.
thanks for the reply
