Steve,

Nice looking diff, but... have you ever autocrossed a lightweight car with a limited slip differential?

1) Limited slip under power will tend to make the car go straight, meaning you can't start to feed in the throttle until you have the car straightened out. Is Phil Ethier still autocrossing? Ask him about the LSD a PO had put into the Lotus Europa he used to autocross. He put regular gear oil in it, and just prayed for the day the clutches would wear out. When they did, the car got much better at handling the tight courses.

2) With the near-stock 907's modest torque, I don't think you'd have too much difficulty managing the wheel spin with an open diff. With a hot rod 2.2 or 2.5 it would be a different story.

Regards,
Tim Engel
