I need help please, When I first finished my car I had 275-60-15 tires on the rear and 225-60-15 on the front, I am using Carrera coilovers all around, I did not care for the stance of the car, {rear end kinda hiked up}, I like the look of the ERA'S, I ended up going to 245-60-15 tires up front and raised the car up front to level, now it seems that when I "get on it" it does not handle like before, like there is a "sway" in it almost,did raising the front of the car cause this some how??. Could I have some how put some "preload" on the rear springs that was not there before? It is no big deal I guess, anyone else have this??
