Need tire suggestions, specifically for more rear grip. I’ve been running the Michelin PS4S which are amazing for the curves and handling, however I can’t put all my power down as the rears immediately spin. Car is stage 2 tuned, catless downpipes, exhaust. Any suggestions as to a street tire with better grip for the rear? Also should i keep the PS4S up front and just get grippier rears? Thanks.
