Went to the track on friday, only made two passes because the tree broke right when i got there and i had to wait like 2 hrs to make my first pass. i ran my car on my heavy ass cobras with street tires. the first pass i had the air pressure at 25 psi, and they hooked ok but i still spun them pretty bad and pulled a 1.88 60' and ran 12.200 at 113.7. the second pass i lowered the pressure to 15 psi and they hooked much better, pulled a 1.60 60' and went 11.80 at 114.2. normal 60' times for me on slicks are 1.55, and i think with a couple more launches and maybe a pound or two less air pressure i could get these to hook just as good as my actual slicks. pretty fucking impressive for a 17 inch tire that i drive around on all the time and works fine in the rain.
there was also a subaru forester there on 4 slicks that ran 11.50 @ 116. it was really fucking cool.
here are the vids:
