Appropriate Wheel Offset for 18" Wheels?

So what setup is the car running in the Autox pics Tom? Look awful small to 18x10's. And the tires are not Hankooks they are Falkens too.


Those were the 265/35 Falkens on the 18x10s. Now sporting the 285/35 Hankooks. Much improved, still trying to work on the Nut behind the wheel. Taking out to the cart track at Adams tomorrow night to see what we can muster. My friend Jake Rozelle has a Camaro that should do very well at Optima this year, and he ran a 44.0 lap there, so I can judge progress reference him. I've finished second a couple times in our San Diego SCCA CAM class in the last couple months, in a 12-14 car field, beating both Hotchkis sponsored Mustangs so the suspension is certainly capable. I'm just running a stock 320HP Magnum 360 with a 4spd OD so I am down on power (and gear ratios) to a lot of my competition...
