i had the prokit springs and wanted to go a little lower up front so i got sportlines, currently running into a problem of hitting the bumpstops when at the track and leaving hard from a light. i can get a set of BMR rears fairly cheap, just wondering what your guys thoughts are as to which would do better, going back to the pro kits in the rear or getting the BMR's. other suspension mods are UPR Adjustable upper and mount, Bmr LCA relo's, Tokico Dspecs, UPR adjustable LCA's UPR Adj PHB.
