Roll Bar
Has anyone installed one of these? How do you like it? Bolt vs weld in?

Re: Roll Bar (GS023)
I would get one that is SCCA approved and installed properly so that it would work. I would also consider a crome molly set up. Its lighter. The down side s are numerous. Hard to see looking out rear view mirror. No storage for the top. I had one powder coated which looks nice and replaced the rear carpeting so we could have a OEM look.

Re: Roll Bar (GS023)
Dave makes some good products, but in all honesty when it comes to a rollbar/cage, you can't beat a custom fabricator.

Re: Roll Bar (GS023)
If you want a real rollbar, check into the ones made by Autopower. I have one (2") and it's great. The brackets are welded to the frame, and the bar is bolted in. If you're careful making the cuts in the fiberglass witha small cutoff wheel, you can put the fiberglass pieces back in when the bar's not in there. Also, spray foam insulation makes it quiet. When the bar's not in there, the carpet covers up the brackets. Visability out the back is very bad, so be sure to remove the bar, which takes about 15 minutes.

Re: Roll Bar (BillWelter)
I've got that one. You can bolt it in or weld it. Great quality and Dave is a great guy to buy from.
PS...that's my car in the pic)
Here are some more pics: http://forums.corvetteforum.com/zerothread?id=636509
From Dave: "Here's a quick summary of the S/T frame. It's constructed of 1.75 x .120 DOM tubing to meet all the latest guidelines. (No you can't store your roof and have a safe unit.) The design was patterned from the SCCA GCR book and should be a legal unit if it is welded in place. As shipped, we supply nutserts with a 14000lb pull out spec to attach it to the frame. As a bolt in unit, it can be removed and new carpet or the original carpet reinstalled and the Dealer will never know you had it in there."

Re: Roll Bar (Gary96LT4)
Why would you want one? It isn't NHRA or SCCA legal. Like the looks???

It is legal if it's welded in.
this frame is not approved by the SCCA to be used as a roll bar because it is not welded directly to the car's frame, it utilizes customer installed "Nutserts" to make it a bolt on installation.

Re: Roll Bar (ncider)
At least one, for NHRA. On the drivers side. That is the 5th point in their 5 point requirement. The photo in the ad is such, that one can't tell if it includes any front side bars, or not. Again, the ad makes no mention of NHRA.

Re: Roll Bar (CFI-EFI)
Where can you buy one that's NHRA legal without having to have it custom fabricated? (95 C4) I always liked the looks of the Doug Rippie bar, but guess that's pretty much the same category as this one. What kind of 1/4 times do you have to push to need something beyond the bar shown here? What are the requirements for a car running, let's say, MAX of high 10s?

Re: Roll Bar (BowTieBlood)
Dave (R-D Racing) will be offering the 5th forward bar for the drivers side shortly, as an additional option, I believe.
I believe it is needed to be NHRA compliant, but I am not real familer with NHRA rules.
I think he just says its not SCCA legal because he is saying to bolt it in, for liability reasons. That's why its called an S/T Frame Support, not a roll bar. To many legal issues in that area.
But if you weld it, it should pass SCCA tech.

Re: Roll Bar (BowTieBlood)
Gary96LT4,
Who is HHRA? NHRA requires ANY bar to be a 5 point. The main hoop (2 points), two rear diagonals (points 3 & 4), and at least one forward diagonal side bar, outside of the driver (#5).
The bar pictured, assuming it is lacking the forward side bar, is NO bar, in NHRA's eyes. A coupe needs a 5 point roll bar, once it goes quicker than 12.00. IF the firewall and floor are unaltered, that bar is sufficient down to 10.00, or 135 mph, which ever comes first. A convertible, without a hardtop, needs a bar at 13.99. In a convertible, at 10.99, and in a coupe at 9.99, an 8 point roll CAGE becomes mandatory. This is just a quick synopsis of the requirements. Any time a bar is required, so is a 5 point harness. There are other rules, too. That'll get you thinking.

Thats for the info on NHRA, and yes, a 5-point harness would be needed, I use one for autox. It really made my times faster. I don't think people realize how much you slide around in the seat until you don't.

Re: Roll Bar (Gary96LT4)
HHRA.....NHRA samething, can't a guy make a type-o?:lol:
I can see how the harness would help in the twisties. For us "straight liners", it just makes it harder to reach controls. When (if) I get there, I'm going to have to move some of my switches.

Re: Roll Bar (mackeyred96)
Here is what an NHRA bar in a C4 looks like.
That is just too nice! What a terrific job they did on your car. I may have to send my car to these guys for the same treatment someday.
Is the curve in those rear points an issue at all from a rules standpoint?
