DOT/Competition Tires for 2012
I have a 2012 Focus Hatch with sport package and manual. I want to take it to do some HPDE events in the spring, but don't want to use the regular rims and tires. A second set of rims and dedicated tires would be good. I've been digging around, but I'm having a hard time finding DOT/Competition tires that will fit 15" wheels. I am leaning towards 15" rims because they and the tires are cheaper, and I want to reduce unsprung weight.
What are the FoFo track nuts using on their 2012's? I want decent performance on a budget. What are you guys using? I checked the Continental Tire Sports Car Challenge Focus ST site but they are running BBS 17".
