Hello! My bike always had the problem: riding a little wide out of corners. GSX-R 600 k5, stock suspension. As a try, we installed a shim rising the rear. 4 mm shim was used. After a 10 lap race (with practice and qualify) lookint ag my front tire, I forund excessive wear. (Tires show no tearing!) Supercorsa Pro SC2 front and rear. Front has visible shoulder after about 70-75 laps (it was a take off). I had a SC1 front looking like the same with 140 laps. Questoin is. Was the 4mm shim too much rising the rear? Can this cause the excessive front wear? Maybe I overloaded the front.... Any suggestions to correct this. Front fork is 8mm below the triple. Which way should I go now? Raising the front or, lowering the rear a little? Thanks! (sorry for bad english!)
