For starters. The Sumi HTR ZIII while a pretty good street tire, not a great AX or track tire.
Get RE-71's for your play wheels and keep the sumi's for street DD use. Another tire to consider for AX id the Dunlop Direzza Star Spec. Not as much performance as the RE-71, but competitive and will last longer.
As far as Alignment
Max out camber front and back
no toe in front and a smidge of toe in the back
Do a search and you will find a few threads on this
