Generally the point of the MINIMUM HEIGHT is to protect the track surface, and to keep from cutting surface mounted scoring loop wires.
In that scenario, the body AND chassis needs to clear the "MIN HEIGHT" tool.
Generally when under power, and under load the car will drop. so if anything is lower than the 5mm or what ever the min. height is, there is a good chance it will drag or scrape the surface.

As far as weight shift I have seen many cars at a 6 mm or greater height with light springs and thin oil that still hit the track.

I have to disagree. Ride height should be the height the chassis rides with the body on. Not how low the body hangs. If a 5 mm ride height is necessary to protect a track then why are f1 cars and 1/12 cars slammed down to the deck? We all know that rubbing a body is not good for speed or handling and the track owner can ask that a body be raised to prevent rubbing and to protect the surface.

Trust me, you can clear the 5mm ride height gauge and still drag the body in 1/10 carpet oval. The ride height gauge is simply to keep, ummm, less attentive racers from ruining the track.

I would love to read the context of that discussion if you could point me to the post.
I do know that ride height NEEDS to be determined with the body on. Many of the local racers need the weight of the body in order to make minimum, myself included. I need to add weight and opted to shoo goo the crap out of my body to add weight and support rather than just add weight to the chasis.
My original question still is unclear. Is ride height determined from the lowest point, body spoilers included? I am inclined to say yes, but I would love to hear from the USVTA on the matter (So i can pass the blame!

Page numbers don't mean anything as you can change the number of posts per page. There are only 327 pages in my view format. Post number is much better.

I am currently working with several different people who race this class and will have updated rules very soon - very soon. ROBK is one of those key people.
At the moment I see no reason why ROAR's rule should vary from a successful and established class.

Any time ride height is checked in tech inspection NO PART of the car, body, battery, screws etc. can be lower than 5mm. That is the point of a ride height rule.
The reason pan cars and 1/12 are 3mm is that the suspension movement is miniscule compared to a touring car.

I would like to get into vta racing, and I see they do it at my local track, any suggestions on a good place to start? As in chassis or which ever?
