Roll Cage Sources Post em Up

One thing I've never understood about the VSR rollbar is why the backstays have that funny s-curve:

Why not just make them straight?

I would assume it's to give more room for optimal drivers seat placement. My autopower bar has the same curve. I'm about 5'10", and with my seat where I like it, I don't have much room between the seat and that harness bar. The harness usually needs to be at less then a 20 degree angle from horizontal, so that spacing helps.

Just to point out that the VSR rollbar comes with reinforcement plates that go beneath the floorpan to sandwich it and spread the load. They need to be contoured to fit in the wheelwells however. While I know this is not as good as welding to the rockers, it is middle ground for those who can't afford a custom welded unit.

I think all roll bars come with bottom plates don't they? My Autopower bar did. If anyone is relying on washers to distribute the load, you might as well just duct tape some steel tubes to your pillars. Because when you roll your car and the whole thing rips loose, it will have the same effect!

Wow, thats an awesome looking cage. The only thing I would want to retain though is the dash, looks like you can't put the dash back in...is this right?

He's not to far from me.

Whats the price range on it?

dash went back in, some of the vents don't work as well :)

Also, if memory serves, when I picked mine up at VSR, they indicated that they would make the front section to make a cage upon request, but I think they wanted the car there for fitting.

Just my $0.02

Is that wiring that is behind the cage in the last pic?...If the rear wheelarch gets into a heavy impact the car will vaporize into a HUGE fireball.....Pleeeeeaze!!!!:loco:I think you are making far too much of this Lee as cars will not have an elctrical fire if fused wires happen to get grounded

Get real. I don't write rules. I just applie them. And if the rule book specifies that no wiring shall be caught between sheetmetal and cage, then be it. Maybe some people here who don't believe in passive safety should also suggest that helmets and Nomex are not really needed. Shhh...

As I mentionned earlier, that cage is very well made and welded, but hopefully the car will not be used in Club Racing. No electrical wiring (especially the battery feed) should be sandwiched between the cage and the shell. Most likely, that cage won't pass inspection unless the wiring is redirected.

I was doing tech inspection at LCMT a couple of years in a row for Club Racing, and indeed having the wiring caught between the shell and the rollcage is (was) a big no and deserved a note in the notebook for correction.

Inspections have gone tougher two years ago, and many cages that were deemed okay in the previous years wee judge not meeting the basic safety rules. I have seen cages where tubings were welded together on even less than even 180°...

Lee,

Not to argue, but I think you'd be hard pressed to find a Spec E30 or K-Prepared car that does NOT have the wiring running as it is in Simon's car. I get your point about why you think it unsafe, but it'll probably pass tech. (Though, i guess not if you are the scrutineer!)

:-P

Very nice work.

If you are in the midwest you can't beat the price and quality of a McMahon cage.

Safety Devices out of England makes kit bolt in and weld in cages. Northstar Motorsports imports and sells them here in the US. Bit more expensive than the Kirk or Evilgenius kits.

i wouldn't do bolt in. if your doing a kit, weld in is the way to go.
