Were you NHRA card carrying racers aware of the 10% pro shop discount at Summit? You need to register and get a member number, it requires an nhra, ihra or similar competition license. When you call, you get to talk to a car guy or gal that knows more than the average phone tech. I'm betting a road race or off road association ID would also work.
https://www.summitracing.com/proshop Just FYI. I believe Jegs has something similar.
