For stock class, I really don't think the car can get it done without shocks. But regardless, run a big front bar and a square tire setup.

I'm running 275 front 305 rear. Didn't really want the 305 rear but it was the best fit diameter wise. I think the front is pretty much maxed out for the stock size rims. Hoosiers would help but I think you'll be cording them pretty quickly with the stock alignment.

The stock shocks actually seem to work pretty well in conjunction with the uprated sway bars, although probably not quite as well in stock class as you are stuck with the stock rear sway bar.
