hate the wheel gap on the rear. this will do the trick? i am sittin' on 20's btw and i am afraid it will rub if i drop the front, thanks in advance...

 

A few people here have the goldlines, front and rear with 20's. If the wheels are the right offset/width you should be ok. Those with rear leveling springs say they work great also.
Just watch for potholes/curbs/deep snow and anything else that will cost you a lot of money.
