i got the highlifter setup and mine are doing the same thing...i called highlifter and the guy i talked to said he has never heard of it..i took him step by step of how i installed them and he said it was right...i thought maybe there was a lip from where they machined the rotors and it would wear off...someone else on the highlifter forum said their's was doing the same thing...with all of these kits sold someone else surely has had this problem and would come up with a solution...the guy i just mentioned said his rotors were not true...i was thinking of maybe putting some silicone behind them to see if it would quit...let me know what you come up with and i will do the same...
