I have a Quaife fitted in my track car, and I must say I am less than thrilled by it. For certain it made a step change to lap times, but still allow a lot of spin on the inside unweighted wheel.
Has anyone spooled their diff? It would certainly be unpleasant to drive on the road as a daily driver, but is there anyone out ther who has done this on their track cars with BE3 transmissions? Big job? Commercial spool available?
