it doesnt scrub at all if im driving normally. it scrubs say if im going downhill and at the end of the hill say i take a LEFT turn, so if i dont substantially slow down for that turn, then my front RIGHT tyre will scrub on the guard.

In my mind the reason is that the shock / spring compresses too much...as its setting is not hard enough....so i figured that if i make the shock / spring stiffer...it wont compress as much...causing less if no scrubbing at all

Before i had it lowered, i never had issues with scrubbing at the front
