Fellow Husker, I appreciate your concern. I share that the cost can be prohibitive especially to family with several kids. It is not required to run MA Nitros, and there will be cars with Cheetas and Cheeta Extremes faster than the nitros due to skill level.
This is a race being touted as "National Championship." As you know, there will cars from all over. Since you've raced there, you realize the reality of tech-in cars from a jillion different rule sets. So therefore the wheel rule must so that A: cars from all sorts of rules sets may run and B: Wheels are simple to tech in. How would you tech in cars with say a 2 gram minimum weight?
While I would sure like to spend less on wheels - cause I don't have a lathe. The stock, untouched inconsistent wheels (which would actually be harder to tech in) wouldn't be fitting of a National Championship drive. I think last year, the nitros were $44 so it's really only a $5 increase for a better wheel.
Which would you rather have leading a national championship drive, Tom Osborne or Bill Callahan?
