There's a lot of comments here that just don't make sense.

You guys act like you race a radial prep track with 33x16's. You don't. Most tracks blow the track off run a Friday TNT. Saturday blow it off again, spray 100-330 ft and you race. The rubber from the race cars and years of vht are what makes the tire stick. You run a given track tune your chassis and race.

Race a big tire big power car, such as Pro mod, on radial prep. It will shake apart. Like racing a radial with full power on a bracket race prep.

No prep on a good track is mostly a gimmick. You scrape all the rubber up. The track is sticky after a good burnout. We have a local track that is a struggle with any heads up car on a regular bracket Sunday. Big power cars struggle not to loose it on top end. They had a no prep race. Pretty interesting first round like any heads up race. After that the track tightened up and racers adjusted. The numbers were within .2 of any other track.

Vht is not a safety measure. It's just what your used to.
