NMCA questions

[steve88]

I am planning to attend the July race in Illinois.
I am licensed for IHRA only is that a problem at a NHRA track? cage is 25.5 NHRA cert.
Are 29" Hoosier DOT tires allowed in Extreme Street?
Coil over springs only, in stock location separate from shocks with after-market UPR hardware. Does this qualify for the -50lbs?

Sometimes the NHRA gets abit "upper-crust" in it's attitude on accepting the IHRA racer/car credentials...the IHRA has reciprocated well in the past but not visa-versa. I'll contact my bud who works over there and get his opinion too.

Tire width will be measured by a “go-no go” gauge. Tire width and height will be measured after conclusion of run at scale area. Tire tread may not extend outside fenders

Thanks,I have been in contact with Mike and Trey.
I use the 29X11.5 QT Pro. I tested some MT 29.5X10.5 slicks last Saturday but they rubbed on the top end. I was informed that DOT tires are not be allowed and my IHRA license is no good for the race. In less than two weeks I can't get in for a physical for the NHRA X-over license.
I am glad I did some homework before making the trip.
