This Speedster Pro Chassis package delivers a rock-solid foundation for your Porsche 356 replica project, expertly prepared by Washburn's Metal specialists. Starting with a clean California-titled donor chassis in balljoint/IRS configuration, every step is engineered for precision, strength, and long-term durability.
The chassis undergoes a meticulous shortening process: mounted on a frame table for straightness verification, precisely sectioned, media blasted for a flawless surface, then internally braced and reassembled. All critical lines are routed, a mechanical emergency brake system installed, floor pans spot-welded in factory style, factory-style seat belt mounts added, fuel line fitted, and a full powder coating finish applied.
Enhancements include:
- Semi-gloss black powder coating (BLK60) for corrosion resistance and showroom-ready finish
- Washburn's Metal front flush-mount kit with professional installation
- Factory-replica 7/16-20 seat belt mounts installed
- Rear torsion adjuster kit with full removal/reinstallation of tube collector and nose cone mount
- Full seam welding on rear frame horns for superior structural integrity under torque
- Washburn's Metal billet emergency brake mount (machined 7075 aluminum with elongated steel pin and hardware) for smooth, reliable operation
The result is a shortened, upgraded rolling chassis ready for the speedster Pro Body kit, drivetrain choice (VW-based, Subaru, or EV conversion), and final assembly. No guesswork, no shortcuts—just proven craftsmanship.
Perfect for serious builders seeking authenticity, reliability, and modern upgrades in one complete package.
