I can't believe you squeezed those tires on there . I think the track must be prepped really bad, or it is just too cold. I was dead hooking on the 275's in 50 degree weather. 240M3SRT was having issues launching on his huge nitto drags too(315s I think), but it was way colder out than 50 out that day.

A few years back I had a LT-1 Camaro with a 175 shot of NOS and I could pull 1.5 60ft all day on 245/45/16 Nitto Drags. It would lift my passenger tire off the ground about 4 inches and made my t-tops leak like crazy .

Good luck out there...We are pulling for you!!
