I need to install a 4 point in my 99 FRC for the up coming hillclimb season. Is this were most people mount the main hoops? 
Is there a location on the floor or the shelf that would work as well/or stronger. The bar I put in my C4 was made to mount to the floor but I modified it to mount up on the stronger shelf.
I build the bars my self from kits from http://www.swracecars.com/ I don't know all that much about the C5 frame so any help would be great.
Thanks
Dave

Opel,
To answer Bill, yes. But there are FAR more knowledgeable people on here than me when it comes to the structural integrity of a C5. I am sure more of them will chime in, but they will probably say the same thing as Bill.

Good progress today: midpipe wrap and tunnel shield. For anyone wanting to know how much wrap to buy, I used 130' and went from the front of the pipe to about halfway up the "U" over the halfshafts. I could have easily used more to go all the way to the muffler.

I'm sure you guys have seen these, but thought I'd share just in case. I had a longacre mirror before and it worked well, but I picked up a Racer's Allview Mirror after seeing a few floating around and Jerry reccommending it. Significantly better than anything I've tried. I was able to get mine used off of ebay from a NASCAR team for like $20 or $25. I think it's def. worth the money if you are going W2W.

Kevin you did a much prettier job with the heat shield than I did 
I used scraps so I didn't have to buy another $80 sheet or whatever it was from CV Products!
As for the heat shield... yes it is structural to a point. Upgrading it to the thicker tunnel plates will increase the torsional rigidity of the car, but now that you have a cage it's worthless IMO. I pust out my air ratchet and long extension for futzing with those.
Looking good
EDIT - What are the bolts/nuts sticking through the floor for?

They are the eye bolts for my harnesses.
The ones coming straight down through the seat stud strip were used in the past for my lap belts. They will now be used for my sub belts which used to be bolted to my seat base.
The one coming through the tunnel wall will now be used for my lap belt since BJ welded in a reinforcement plate against the tunnel. On the door side, I will now use the OEM seatbelt bolt as the mounting point for that lap belt.
Thanks for the compliments. I spent $110 on a 36"x48" sheet of thermal material from Summit and still have some left over.

Wrapping stainless (esp 304) is generally a no-no, but the temps are lower in the mid-pipe vs the headers so you should be alright.

C5s (and I guess C6s) benefit greatly from wrapping the mid-pipe. It keeps the clutch hydraulics cooler which allow them to work better along with acting as a poor man's trans/diff cooler by keeping some of the radiant heat out of them.
