370z ASP Wheel Tire Hoosier A7 295 or 315

Tracer 09

Guys been reading and was wonder if a Hoosier 315/30/18 will fit up front without rubbing or do I need to drop down to 295's. Set up right now is Koni Yellow with Swift Springs. This is for local competition and not for national competition as of right now. Was running in STR but am tired of running the 370z on 255's. Have a local Boxster guy in ASP that I want to have some fun with. Will be moving to coilovers later this year or next depending on funds. Wheels are 18x10.5 with 35 offset. Front camber is -3 front and -2 rear. In the rear was planning on using a 10mm spacer with ARP studs front and rear. I was planning on a 315 square set up but if I can only fit 295's up front should I go with a 295 square set up or run staggered? Have Hellwig front bar and no rear sway bar. Thanks in advance for any input.
