Reconsider the IRS. For a fun street car, the IRS provides a much smoother ride and better control. Well worth it. Changes the entire charector of the car. I would never build another roadster with a solid axle.

The 9" is definatly overkill, unless you'll be drag racing with slicks and a lot of torque. The 9" is bigger, heavier, and less efficient than the 8.8 without providing the average driver with any real advantage. Probably more expensive, too.
