Chassis stiffening

1993–98 Toyota Supra Mk IV (A80) chassis stiffening

2 kits to stiffen the body shell, from frame rails and connectors to braces and roll bars.

How it's built
Steel unibody
Weak spots
Rust is uncommon but can appear in the rear wheel arches and lower panels on cars from salted regions. Most cars now need bushings, ball joints and dampers, and the soft rubber subframe and differential mounts allow wheel hop and vague rear response.
