Hi all I have just bought a 2003 VY HSV which came with 19" mags which are rubbing on the guards. I assume because it has been lowered. Could anyone tell me what the factory standard ride height is and what the factory spring part numbers are? I would like to keep the mags but would like to raise it up to stop the rubbing. Sorry new to this and may be asking stupid questions but hope someone may be able to help.
