I just installed Hal double adjustables on the rear and went from a 26" Hoosier QTP to a 27" Hoosier QTP. My old setup was hitting the tire way too hard (M6 car) with stock shocks. This showed up on slo mo video as the poor tire was being crushed to the rim at launch and had a good bit of rebound. I'm thinking I need to set the rebound **** up pretty high to remove some hit. Any body running this combo willing to share some setup info. Two changes at once should be interesting to say the least
