i installed my camber kits today. i have h&r sport springs and 17's. the tires on the 17's are shot. i have had them on for a year with terrible camber. i took the wheels off today to start putting on my kit and i looked at the drivers front tire on the inside(where it was worn) and it had been cut it looked like. you could see the belt and everything. i know what is cutting it. it is about in the middle of the wheel well on the top. it is a little lip that comes down.

can i cut this off!?!? i hope so because i have potenzas on now and i cant shell out 170 a tire all the time. i need some solutions please people.
thanks in advance
