Understood. But I wasn't sure how much of this was because a radial tire works better w/ the chassis tuned differently than a bias-ply, or because of all those other variables like HP, etc.
.. correct me if I'm wrong but aren't most stalkers running a radial now...
Yep. Pic below is the 2017 Stock Finals at Indy showing two 10-sec 340-powered cars pulling 'em up, a lot of chassis separation, and planting their 9" radials.
