Inspection clarification.
 

I was planning on buiding my current car for either NASA TT or the Redline Time Attack. The Redlines rules state it must be of the original unibody and I'm sure NASA has something similiar in the rules.

The situation is that the car was in an accident with the previous owner. The driveside rocker panel incl. the door sill (from roughly the front of the door to the rear wheel well was replaced. That entire section is at least 4in from the "frame rail" under the car. It was welded in and the body is straight and drives true.

I'm unclear as to whether this replacement voids the "original unibody" or if they just care about the outside appearance/drivability. I'm sure I could get an absolute answer by referring to an official inspector, but I figured with the wealth of knowledge around here, someone would have an idea.

Thanks for any input for these classes or any other classes including autox and such. :)

Should be no problem. I'm more familiar with SCCA rules, but I have never seen a case where industry standard body repairs would disqualify a chassis. In fact, in race cars it's pretty much assumed that you will have some sort of body repair of this nature, if not now then soon. :D

I suspect that when they say "original unibody" I they mean "original for that model/line" in order to prevent someone from tubing the frame out or adding lots of chassis bracing.

odd they dont clarify that better, they usually overdo that...

they mean that the unibody is rebuilt to original specs, not that its factory original.

TT is nice, its not really wheel to wheel, it keeps the cars nicer

Excellent. Great to hear.

As for industry standards....I might have to get some of the welding redone but that shouldn't be a problem.

Hell, I've seen cars that have had the front half replaced on year and the back half replaced the next! So the whole car isn't the 'original unibody' but its still the same car.

Like George Washington's axe, the head has been replaced twice and the handle has been replaced 4 times, but its still his axe.
