Rear Suspension Mod.s and Improvements
Project Introduction

The project's objective was to improve handling, update technology, replace worn parts, and inspect the frame structure for fatigue and cracks - Ye Beast has been operating with a Chevy small block V-8 for 40+ years. To improve the handling, the rear track was widened 1 1/2 inches per side. This provides more stability and allows the replacement of the longer main leaf and the second longest leaf to increase spring rate. Where possible, I upgraded to newer technology, or redesigned structural elements including the trailing arm brackets.

When Ye Beast was created in 1970, the track of the Vette' rear suspension was narrowed by 7 inches to fit the Spitfire's body width. In 1995, the track was narrowed another 3 inches to enable the use of wide, 50-series tires - the transverse leaf spring was shortened to fit and it was necessary to remove the second longest leaf. The result of the second narrowing was a reduction of the spring rate which caused unwanted cornering and acceleration effects.

Photographs recorded the project's progress. Photos were not taken during the initial construction in 1970. A page, with photos, has been included that explains the initial installation of the Vette' suspension.
