Our cars couldn't be more different but I'll throw my opinion in. I have a 2006 GTO street car that I race on radials (Small Radials) and have done quite well. I've had my car 8 years and it's always been on a drag radial. We are close on et, my best is 11.86 @ 114 mph with a 1.57 sixty foot. 3600 converter and 3.90 gears . Car weighs 3900+ with me and full tank. My front shocks I run full loose , my rear shocks are QA1 single adjustable i run on 8 clicks. I run a Mickey street R drag radial. Drive it on the street with 35 psi and race it with 26 psi. Finished #8 in points at my home track to years ago. This past year I ran my Chevelle in Pro class points . Hurt the trans in the Chevelle and jumped in the GTO to fill in so not to miss any points races. After the trans issue a fuel issue happened. So the GTO had to fill in for 3 points races. With my street car on drag radials , driven on the street I found myself #2 in points by the time the Chevelle was back in action. Finished the season #2 in points just one round out of 1st place ( last points race rained out so we will never know) If not for my slow drag radial street car keeping me in the hunt it would have been a bust points season.
