If the track is not too bumpy, then the stock springs are a good place to start, go 3 hole pistons and 300cst tune with springs from there depending on how well the car is riding the bumps. Also if its bumpy, you can be spring more if the bumps are hollows rather than jumps. I run in the same class on a similar grip very bumpy track on foams, I went down 1 spring rate on the front and 2 on the rear, with anti roll bars 4 on the front and 3 on the rear.
