Tuesday Tech Question


I’m building a Pro ET 1984 Mustang that I think will run 11.30 in the 1/4-mile.  I was thinking about running the original front wheels to start with and wanted to know if I use the OEM wheels will I be able to run the rubber valve stems?

Valve Stem Vern,

In the 2012 NHRA Rulebook, General Regulations section 20 page 28, 5:1 Tires it states “Metal screw-in valve stems mandatory in tubeless tires, front and rear, on vehicles running 11.99 or quicker.”
