Traveler2 Thanks! Not like I have much else to do, but practice right now. The LM being excluded makes sense as it does drive significantly better...may just need to drive it and post the times as "Stock" class if I get any decent ones. The diff is not visibly broken, but after only a few laps it will lock. If you slightly force the wheels in opposite directions it will unlock, but not spin as free as it did when new. I took it apart and you can see some mushrooming or excessive wear on the outer edges of the planetary gears and the ring gears. It also seems to have more axial play then the one in my LM car. Any trouble shooting tips would be greatly appreciated. Not used to working on things this small!

My handle was given to me by a friend decades ago. He always gave me crap for being so cheap except when it came to cars and racing I figure I am actually from a Jewish family so if the shoe fits!
