ZHP Fam!

I'm planning necessary changes to my 04 ZHP to do some tracking with CCA in the PNW in 2021. Need some extra seat time, my race ride is in SoCal.

Anything that is 100% recommended? I'm gonna snag a square 17 setup as a secondary set of wheels and tires, but curious to what else is a good call to upgrade or strengthen.

Thanks and Happy New Year all!
