Stopping the Unlimiteds can be a problem. I use dynamic braking, metal stop strips, towels and a catch box. The Cars are probably still hitting 30 MPH when they hit the towels. Only the bodies occasionally get knocked off, no harm to the chassis. Some of these cars must have 100 runs on them running those speeds. Tires are the biggest problem only Silifoams stay on at those speeds.
Next up are the Inline Super comp 2.5s. This is the largest class and should provide some great racing:
Inline Super comp top qualifier at the 2019 Smoky Mountain Fall Nationals is:
Triple 52 running a .4399 @ 30.57, Congratulations Triple 52 on your first TQ. Winning this class will not be easy however as there were 4 cars within .01 of each other at the top of qualifying. Should be some great racing however.
