The Hotchkis big-block coil springs accommodate the weight of the six-speed and new engine accessories, and they snuggle into the Detroit Speed spring pockets. The small-block ones couldn't be used without going with a shorter front tire and would have caused clearance issues. The stock drum spindle was cleaned and powdercoated by Robbie Morrow (CPC Stripping and Powder Coating). Robbie powdercoated the subframe in a contrasting color; it will remain virtually chip-free, enhances overall appearance, and is easy to clean. If time is not an issue, then spend those 50 or more hours smoothing the subframe.
