Re: Am I NHRA legal for 11.0-11.99? depending on the track, some tech people follow slightly different guide lines, I thought you only needed steel valve stems on slicks!, also, if your running slicks you'll also need extended studs and C clip eliminators, duhh a helmet, I have my rule book in the car, I'll get it later!

Also once you hit 10.99 a trans blanket on an automatic is required, a SFI-approved balancer is required 10.99 and quicker, and aftermarket axles are required 10.99 and quicker.
