That sounds good, although if you can I would suggest milling down the front steering knuckles (ie shaving the bottom off so you can get some more ride height out of your tires) i dunno if bruce sells them, he used to last spring i think....
Otherwise sounds fine, let me know how it goes on the track.
One thing i have wanted to try if you really need rear grip and have enough steering from the front end, is to slam the roll centers, however i havent run asphalt since the worlds last october so i havent gotten a chance to try it, since on carpet it would lock in the rear end too much.
