I have replaced the clutch, with a stage 2 ClutchMaster. I was told by one of the mechanics an LSD was not necessary and has negative effects in most driving circumstances. I keep "shredding " gears. I was told a while ago of a company that rebuilds trans. with taller gears and welds them as we'll as shot peening. I however cannot find the site. I am looking for someone local and competent to do the job.
