Lighter = Faster (N/A build thread #2)

Snapped a couple pics when I stopped by the shop yesterday to drop off the roll bar.

The pieces of tape everywhere are holes that are going to be filled in.

The shop has some interesting ideas about the roll bar. I need to look into the NASA and SCCA rulebooks to see if it's legal, but maybe someone here knows. I want to keep the bar bolt-in but I wanted more strength at the attachment points so I asked the shop to weld some 3/16" or 1/4" plates to the car. They came up with a neat idea to build little boxes at the attachment points with welded nuts inside. This way the attachment points should be much stronger and I won't have bolts going through the body of the car. Legal?
