FAQ

Are your roll bars and cages weld in or bolt in?

All S&W roll bars and cages are designed to weld in. The tube ends are notched where possible to reduce the time necessary for installation and save you money.

I don't see a roll bar listed for my car? What do I do?

S&W is continually adding to its list of over 2,800 make,model & style listings, but if you don’t see your car listed, call us or send us an email and we’ll send you a roll bar measuring packet. Once you’ve measured your car send the info to us and we’ll custom bend you a roll bar or cage to your specifications.

How much lighter is chrome moly bar than mild steel one?

Chrome moly steel and mild steel would weigh exactly the same if it was the same wall thickness! But the weight savings comes from the higher strength of moly tubing which allows the use of a thinner wall thickness. Our roll bars & cages are made from .134″ wall mild steel and .083″ wall for moly. Since the wall thickness can be 38% thinner with no sacrifice in strength it is therefore 38% lighter. In simpler terms a roll bar that weighs 100# in mild steel will weigh 62# in chrome moly.

How do you keep from burning the headliner when welding the top of the roll bar or cage?

The thing we do to weld the top of the hoop is, slip a piece of aluminum between the headliner and the bar and have somebody push it up off the hoop so you can weld. You should only have about and 1″ to weld on top.

Some guys will cut a hole in the floor where the 6×6 plate goes and pull the plate out drop the bar down in the hole weld the top pick the hoop up slip the plate back in place and finish welding the bar to the plate and the plate to the floor.

What do I attach the bottom of end of my frame supports to?

The bottom of the frame supports should attach to the sub frame connectors. Note; The frame supports do not have to be in line with the main hoop. If you are installing an 8-Point in a car that does not have sub frame connectors, weld 1/8″ plates to the floor pan and weld the frame supports to the plates.

What should my pinion angle be when using your 82-02 bolt on Camaro torque arm?

We recommend that the pinion angle be set between zero degrees and one degree down.

How do I measure the pedal ratio and what pedal ratio is best suited for my application?

Pedal assembly ratio, or mechanical leverage is the ratio calculated from the length from the pivot point of the pedal to the center of the foot pedal (A), divided by the length from the pivot point to the master cylinder pushrod (B). Refer to the figures below. Mechanical leverage is simply a means of increasing the brake force without increasing your leg effort. As “A” gets longer and “B” gets shorter, the mechanical leverage increases brake force without pushing harder on the pedal. The disadvantage is that the pedal stroke also increases, requiring you to push the pedal further. With a 1″ master cylinder stroke, a 100-pound push onthe pedal, and the pedal having a 4:1 ratio, the force is 4 x 100 = 400 pounds, and the stroke is 4 x 1 = 4 inches. With a 100 pound push on the pedal, and the pedal having a 6:1 ratio, the force is 6 x 100 = 600 pounds, and the stroke is 6 x 1 = 6 inches.

If uncertain about which pedal ratio is right for your application, a 6:1 ratio is an excellent starting point.

A = Distance form pivot point to middle of push / pull point
B = Distance form pivot to point of push on master cylinder
P = Pivot point
F = Force or push
