OK. I have 4 lug BBK 17in cobra R's with Nitto DR 275-40-17 on the back. I have had these for just over 1 year. On the street these tires kick major AAss(but not in any type of weather). On the track my BEST 60 ft is a 1.92. Which sucks ballz for a DR. Probley because there is little sidewall on them. Also, and this is just my thought, dont get the standard cobra R's. Everyone seems to have them now(When I got mine, very few did.) Try geting 2000 cobra R's or the 2002 Cobras from Performance Wheel Outlet. They are very close and will set your car off just a little better than all the rest.

If tracton is the issue... get some Bogarts with some 315 BFG DR.
