SETUP GUIDES

These specific setups are designed for Hyper Micro Sprint/Mini Sprint Chassis, Lightning Sprint, Asphalt 600 Sprint, and Midget. If you do not have a Hyper Chassis, consult your micro sprint chassis manufacturer for a starting setup. If your chassis builder does not offer a starting setup, you can use our setups and measurements, keeping in mind the differences in your chassis. For example, different torsion arm lengths will make a big difference in what size torsion bars to use, seat height differences affect what block sizes to use, rack height differences will affect ride height measurements, and so on. There are countless variables.
