For many years, I'd been running track events with a 5-point belt system attached to a simple harness bar that I'd fabricated for my 944 Track Car. As the years went by, It gradually began to dawn on me that I was going increasingly fast... too fast it seemed to me for the comfort level that the old harness bar offered. Sure, like everything I build, it was rugged as heck, but... What to do to improve things?
Like many people, I checked into some of the commercially available bars that others had
You can purchase several roll bars or cages that are variously well made and relatively inexpensive, but do these really do any more than meet a minimum requirement for participation? Most of these devices bolt to the floor and/or the rear wheel wells with .125" backing plates as insurance. If your car rolled onto its roof, would the force applied in compression to that thin floor/wheel well withstand this force without ripping through?
The next thing to be compressed is you!
Quite frankly, most of these old conventions are hopelessly outdated and do not represent anywhere near the state of the safety equipment art. REDLINE Four Point Harness Mount Bars fasten to existing reinforced factory seat belt mounts. These areas provide far greater strength than flat sheetmetal floors or wheel housings. With the 4-point harness bar, the loads would be transmitted through the reinforced factory seatbelt mounts in a parallel (tensile, or tearing) fashion -vs- the perpendicular (or piercing) force applied by most bars into thin sheet metal. Is it easier to tear a piece of sheetmetal... or poke a hole in it.
Perhaps the best feature of REDLINE Bars is that installation is easy using regular hand tools, requires NO PERMANENT MODIFICATIONS to your car's interior, and for those still driving to events... they take up very little room! They are constructed of MIG-welded 1½" and 1¾"x 0.95" wall mild steel tubing.
installed in their cars. You know; they were OK I guess, but they really didn't impress me for a number of reasons.
If you participate in Driver's Education , and are considering adding safety equipment to your car, what is your first priority? Is it to merely meet the minimum standards that are required? Or... should it be to actually provide yourself with some potential safeguard against injury?
You can buy any number of "Belt Guide Bars" to add harnesses to your car for Driver's Education (a good idea!). However, Belt Guide Bars usually mount only to the relatively weak "B-pillar" in your car. And besides, they are generally NO LONGER LEGAL for mounting your shoulder harnesses because they are not designed to withstand the force generated when your car experiences. "Rapid Negative Acceleration"...but your body doesn't!
I have 944 Harness Bars designed for use in Driver's Education. Of course, I can custom build any type of roll bar or cage for any vehicle and requirement you may have, and I would certainly be willing to consult with you on your project.
