You should be able to run a 275/325 (or 275/335) combo if you work with a vendor who can properly specify the backspacing for the wheels. DSE's recommendations are conservative.
I would go 265/35 F and 315/30 R. You can go Falken RT615K or Rival, both are great for a mix of street and track. I have a pair of new RT615 K 265 Fronts for 1/2 price if you want to try them, if they don't fit I'll take em back...
