buy SSSL king springs for the rear and SSL for the front (front may scrape a little on SSSL) ride is still good on standard shocks. but buying monroe shocks (if it were me rear only) they will drop the rear a tiny bit more
you can get the springs put in at any mechanic dont just look at suspension related businesses.
and coilovers are pretty much height adjustable springs, you can choose to have them wound up or wind them right down and youll be sitting LOW, also less hassles if you were to ever be defected for height as the VE rear springs are about a 2-3 hour job .. costly
and coilvers are around 2.2k + but would probably be the best option
