mounting the 6x6 plates for a 8 pt????
hey guys i have been searching the treads looking for some pictures of where people are mounting there 6x6 plates for the side bars and rear supports i'v been told to get them as close to the shock towers as possible but i look at some peoples and there not even close... so if you guys could post some pics of where the best spot to mount the rear supports and the side bars. Also is there a regulation on how far the down the hoop the side bars are welded (the lower the easier it is to get in and out)... hey guys any pics or info would be greatly appreciated.
Thanks
Brock

There is no 100% specific place. The main hoop fits best on the hump behind the front seats. The front plates for the door bars can be anywhere from just forward of the door opening to the firewall. The bars that come down behind the seats towards the driveshaft tunnel normally tie into a SFC if possible. The rear bars can be anywhere from near the shock mounts all the way to the back part of the sheet metal frame rails. My rear bars are located on top of the hump.

With the rear bars there isn’t really any specific location that they have to go to, they just have to meet the main hoop at more then some minimum angle and within a fairly close distance to the top of the main hoop.
Probably the strongest place to tie them into is the sheet metal right around the shock or all the way out to the sides above the spring pocket, but people put them everywhere from the shock mounts back. Some people swear that they have a safer car by putting them all the way back to the raised area in the rear sump because it’s “protecting the tank” but in real life unless you add some solid member to the bottom of the car back there to triangulate the structure, you’re basically just making the part that is supposed to protect you weaker and sticking some bars into an area that was designed to crumple and absorb energy in an impact.
The main hoop plates are supposed to be either tied into the frame if there is one or the rocker panel seams (usually the most structural part in that area on unibody cars), and the small diagonal braces back there are supposed to tie the main hoop into the suspension pickup points, but it’s rare that people do a good job at that.
The locations of the front bars are like the rear bars, no real specific place to go as long as things end up at the correct angles and the door bars cross between the shoulder and elbow of the driver.
I think in a perfect world they should come down where you have the multiple layered joint where the rockers, front door hinge pillar and floor come together.

I've got my rear tubes going to the top inside corner of the rear bulkhead and shock pocket. Although it was a pain heating, tack welding, and hammer forming it to fit, that's the most rigid part of the rear body, since you have both the shock loads going there, and the rear springs are close by.

BOTTLEDZr28 i really like your set up! I was wondering if it was race legal and could the rear bars be pushed apart a little more for more head room?

once there is a cage in the car, you can NOT use the backseat at all anymore. Despite what some people on here argue, in the event of a crash a person sitting in the back seat has a high probability of death due to crushing of the skull into a bar.

Now I’d probably just use my home made press brake… I just formed a “pan” out of the same gauge steel that’s 16” wide with a 1-1/4” lip around all the edges to hold 2 gas bottles on the back of my new welder rack…
Not that I would recommend it to anyone, but I’d be shocked if this was anything more than a myth. Yes, the bars are there, and yes, they are hard, so just pad them with proper SFI style padding. I don’t see how the main hoop /down bars like that are any different then the halo bar or side bars and windshield bars are to the driver, and it doesn’t take anything near that hard to cause harm (I was t-boned in my ’83 by a driver going about 50mph on the passenger side, smacked my head into the padded roof section between the t-tops and ended up with a concussion).

I heated and formed the side plates to fit the contour on the sides for the main hoop.

The rears are right by the shock mounts.

This was actually taken out of this car and size straight side bars now. not low bent ones like these pic's.

Looks great and also looks as if is probably pretty quiet too. Nice job.
I am guessing that it is all mig welded in place.

on the 4130 cage. Looks as if the shop did a great job of installing it. I will be nice to see it once it is all finished. Are you planning on keeping the heater and or AC in the car? Just curious. With the full cage and the front down bars I know it is hard to sometime keep that stuff.

There's pictures here on what I did with my 6 x 6 plates. They always require some form of trimming to get them to fit.
