My question: Are these rear braces that extend off of the B bar allowed to have a bend in them? I'm planning on passing through the for easier access into the trunk area? I'm planning on passing through the package shelf area. Thanks. 11.02 @ 120 mph - Slant 6 & Turbo http://www.youtube.com/watch?v=EAxRmoDgsdY Chassis Dyno http://www.youtube.com/watch?v=wd6hFGzLJMc

We mounted our rear bars behind what would normally be the backseat I've seen many Camaro's certified that had the rear bars bent to fit thru the speaker cutouts. We bent our sidebars to contour the stock door-panels, and its never been an issue with tech inspection. Although our bars not certified not a 9.99 car....and at that point we'll need a cage anyway.

The car will be in the 10's and not any faster unless I find a lot of weight to remove or a bunch more HP! More opinions are appreciative. 11.02 @ 120 mph - Slant 6 & Turbo http://www.youtube.com/watch?v=EAxRmoDgsdY Chassis Dyno http://www.youtube.com/watch?v=wd6hFGzLJMc

Ideally, the braces should be attached to the rear frame rails above the suspension mounting area. On a leaf spring car, that is pretty far back and is NOT a requirement. An X-Brace is also recommended, but not required till a roll cage is needed. Also remember the seat back must be attached to the roll bar. Scott 6211093-1618.jpg (151 downloads)

I'm wondering if I could start at the legally required point(say 5" down)on the main hoop and then take a sharp bend down and exit through the bottom of the rear window and then turn acutely again into the box area to attach at the frame rails. This would keep everything inside the cab and box. Tom 10.56 at 125.6, with a 1.43 60 ft. E85, Hyd. Roller 410 magnum,full exhaust, 3500 race weight.

IHTMS 8 point like the picture above. Thanks for the pics and advice! To help clarify( I hope) the diagram of the "8 point roll bar" is actually a six point roll bar with the two (smaller diameter tubing usually) lateral stiffener to help keep the main hoop from being pushed over in a roll over crash The picture of the roll cage in the car is a ten or twelve point cage, depending on how many points are going forward that I can't see in the picture Maybe I've got it wrong and what I have always consider a six point roll bar is now a eight point roll bar Mr.Cab Racing and winning with Mopars since 1964.
