Restore your classic Porsche or performance vehicle to factory condition with high-quality chassis and repair panels from Design911. These precision-formed metal panels are essential for rebuilding, reinforcing, or repairing corroded, damaged, or weakened areas of the vehicle’s body and frame.
Each panel is manufactured to exact OEM specifications or improved aftermarket standards, ensuring a perfect fit, correct contour, and long-lasting protection. From floor pans and sills to inner wings, bulkheads, frame rails, and crossmembers, Design911 supplies everything you need for a professional restoration or body rebuild.
Our panels are made from high-grade steel, aluminum, or composite materials, treated for corrosion resistance, and designed for straightforward welding or bonding installation.
What These Products Do

of your vehicle.
They:

Restore
the car’s original shape and panel gaps after rust or collision
damage
Prevent

Symptoms of Damage or Failure
Visible signs that your chassis or body panels may need
repair or replacement include:
Ignoring these early signs can result in further rust
propagation, weakened structural integrity, or complete panel failure - especially in older or classic vehicles.
Common Reasons for Failure
Why Replace or Repair - Replacing damaged or corroded chassis panels ensures:
Whether you’re performing a full chassis restoration or localised rust repair, proper panel replacement protects your investment and brings your vehicle back to its original glory.
