I know this post is older but just picked up my F80 and about to take to the 1/4 track to race a Camaro and Challenger so this caught my eye.
The 11sec time slip is impressive to me with a 2.1 sec 60ft. I know the
Toyo R888 allowed me to run a soft 1.7 sec 60ft with my C7 and 600rwhp,tq on a not so prepped track (was pulling a 2.34 60ft on street tires
before the Toyo's). I ran a 11.69 at 126 DA 8200 that night.
