Tuesday Tech Question (04/29)

The Tuesday Tech Question is a fun section where prospective technical inspectors or anyone who wants to get a better idea of how to work the NHRA Rulebook can test their knowledge and search abilities. If you have an NHRA Rulebook, try and find the answer to the question in the book before looking down at the answer. If you don’t have a Rulebook but are an NHRA Member, you can download a pdf at nhra.com under ‘Member Benefits’.


I recently purchased a Toyota Celica Pro Mod style car.  I plan to run the car in the Top Sportsman class along with some local bracket races.  I am looking to upgrade the wheels before I start racing the car.  My question is, am I required to run beadlocks when I run Top Sportsman?

Beadlock Bill,

For the Top Sportsman class, any vehicle that runs 6.50 and quicker or 210 mph and quicker is required to have rear wheels that meet SFI Spec 15.1.  Additionally, these wheels must have beadlocks or liners.
