You should think about a welded diff. It made my car a lot faster.

I have the swaybars and still get a lot of lift most notably at Sears Point (ok Infinion).  We lowered the car during the post season so I don't know yet if that will help.  I know that some guys have swithch to some type of locking read end as a solution. Gary- are you following this thread?
