building new GTS

I recently bought a Panoz GTS chassis and body that I'm building as a track car, lots of work to do but wanted to talk with someone who been racing one for a while. Try to get some ideas on setup - sway bars, spring rates, etc and other changes that should be made. Pretty much starting with a bare chassis. Have already addressed some of the know weakness in front control arm mounts and rear arm mounts. Going with 5.0 Coyote, here's a pic

Any updates to this build?
