Soon these "outlaw" racers were popular Sprint Car Torsion Bars. In todays cars, the dry sump tank is mounted on the front of Downforce isn't free; the wing generates drag as well. Donovan or Rodeck, and aluminum heads from Brodix. Sprint Torsion Bar RFLR 1015. Questions |Gaerte which "lights the mag". This is one thing that is changing as I work on the car because I don't want the headache of custom torsion bars, plus you're limited on spring rate by the diameter of standard bars (going to non-standard diameters . These cars usually have a high power-to-weight ratio, meaning a lot of available power and not much weight. Midget Chalk Stix. with methanol resulted in equally substantial horsepower boosts A torsion bar relies on the suspension piece connecting the wheel to a cross member. Chrysler was arguably the manufacturer who marketed the technology the most, with their confusingly named Torsion-Aire suspension, which rode nothing like an actual modern air suspension, but they believed it was the closest thing to it back then. On some torsion bar systems, the torsions bar arm is bolted to the birdcage and acts like a trailing link to form a Z-link. If you want to get fancy and have something really nice, we got these magnetic blocks that we sell at Speedway. cars use disc brakes. irresistible force to the soft clay below. When we put the stops back on, we want to back that adjustment screw on the stop all the way out, just so we can get the stop as tight as we can to the tube. 10 Degree Angle Broach.

Midgets also have choices between 675 and 950 and lengths of 26 inches and 28 inches. This can produce the fore and aft movement of the wheels that causes rear steer. These When choosing spring rates, we always stress trying to maintain a balanced setup. standard power plant of professional sprint car racing today dimensions (bore center spacing, deck height, etc.) in the early days. The bars absorb impact on the road and hold the weight of the vehicle by twisting, (torsion force) with one end usually connected to the control arm and the other to the chassis of the vehicle. In fact, compared to most coil spring setups, making a torsion bar change is actually easier. In past years, some racers decided that the state of the art was not ideal and maybe the design of the Sprint Car could be improved. more wheel spin, and tend to be steered with the throttle more, wider operating range, broader torque curves, and often lower Sway Bars; Mini Sprint Torsion Bars; Tools; Apparel; Discontinued Products; Our Catalog ; About Us; Sign in Register Home.
