It was entertaining to have Zung's 4-door, daily-driver BMW in the shop for a custom-fitted 4-point roll bar. Every visitor to the shop asked why someone would want a roll bar in a car like this, but we enjoyed telling them that Zung is an experienced driver who regularly competes in NASA time trial and BMW Club events.

Zung asked us to build a great-fitting, structural roll bar that would be removeable, allowing him to remove and replace the bar. The fact that this car has 4-doors made this mission somewhat difficult, since the doors are shorter than they would be on a 2-door car. We also wanted to make this bar fit as well as all of our custom-fitted bars and cages, which meant that there would be little space to fit the bar inside the door opening. After careful planning and attention to detail, the end-result is a great-fitting bar that maximizes driver headroom, but is still removeable for everyday driving.

This bar was made from 1.75" x .120" DOM mild steel tube, and includes a diagonal bar as well as driver-side and passenger-side harness bars. We CADed and plasma-cut the mounting plate system, which features threaded lower plates that are welded to the rockers and rear bulkhead of the car. The bar is welded to upper plates which feature alignment holes that fit onto the lower plates, allowing the bar to be bolted-into structural areas of the car while still being removeable.

While the car was in the shop, Zung asked us to fabricate custom harness mounts and a fire extinguisher mount on the bar.

Matt time-trials his C5 Corvette, and is in the process of turning it into a track-only car. He asked us to build a roll bar that would provide more safety and would serve as a strong foundation for later turning it into a full cage.

Matt chose to have the cage made from 1.75" x .120" DOM mild steel. After reviewing various Corvette roll bar and cage designs with Matt, he asked us to attach the main hoop to the floor behind the seats. This area features a narrow strip or steel which serves as the rear support for the seats and for the fiberglass and balsa wood floor. Since we wanted to make the bar as structural as possible, we decided to weld 1" x 2" rectangular tube across this area, to tie the outer frame rail to the center tunnel. We welded 1/8" plates to the frame rails and tunnel, and to the rear bulkhead, and then welded the rectangular tube to these plates to help distribute loads across a greater surface area.

Tom’s SN95 Mustang has a Vortech blower and gets driven on road courses in various events. Tom asked us to install a roll bar that would give him an added degree of safety and would also be legal for open-road events like the Silver State Classic. Based on the SSC requirements for his expected speed, this roll bar follows NHRA rules and features removeable door bars and additional X bracing inside the main hoop.

We used DOM tube for this roll bar, which was custom-fitted to Tom’s driving position.

Notice how the main hoop follows the contour of the car’s B pillar, and how tightly the rear braces follow the curve of the roof and rear window? We take care to create a roll bar that is not only sturdy and NHRA-legal, but also enhances the appearance of the car.

This level of fitment takes time and care, since the tubes are so close to (yet not touching) the headliner and interior trim. This is just one example of the level of effort and customization that we put into our customers’ projects!
