19. System Design Often the steering system is designed late in the building process. We recommend that the steering be mocked up at the time the engine and exhaust components are installed. Positioning of the column, shafts, and U-joints, with respect to the engine, exhaust, and steering box early on can help in selecting the correct parts. With our wide selection of U-joints, shafts, and vibration reducers, any system can be designed or modified to result in a car that is not only safe, but a pleasure to drive. Keeping a system simple is the best course, but even a system with up to 10 U-joints can be designed as long as the proper phasing and supports are used.
