If you're running a power-limited class such as Pure Street, then you need to maximize what you have. Most of these cars have detailed suspensions that receive a lot of attention in testing and qualifying to fine-tune the combination for the particular track. Denny's Cobra has the full QA1 front suspension working with Strange coilover struts and Hypercoil springs. In the back, QA1 12-adjustable shocks work with Metco adjustable upper and lower control arms to plant the 26x10.5-inch slicks. Short times in the high-1.30 range are not uncommon for a little Pure Streeter-this one has already dipped into the low 1.40-second range.
