Datsun Comp 1200 Suspension Manual with Blueprints

This is the ultimate Race Car suspension book. It contains step-by-step instructions, dozens of detailed drawings, and most important, a complete set of working blueprints illustrating every piece necessary to duplicate the suspension of Datsun's 1200 C-Sedan Championship car. The blueprints are full scale and complete in every detail. Every dimension, specification and material requirement is called out and all modifications are clearly outlined. The suspension system illustrated in this book was designed to be both inexpensive and easy to fabricate, and it has proven itself repeatedly in competition. Note also, that while the project car illustrated in this manual is a Datsun 1200, the principals outlined will apply to any car with a MacPherson strut front suspension and a live rear axle.
