2 kits to stiffen the body shell, from frame rails and connectors to braces and roll bars.
- How it's built

- Rust shows up in the rear wheel arches, rocker panels, lower doors and around the targa roof seals. Lower ball joints are a known failure point, and the rubber subframe, differential and arm bushings are usually tired.
