THE ONLY STREET-LEGAL RILEY CHASSIS

Hand-Built Chassis

  • Cars are disassembled and all bodywork panels removed. Original steel tub retained.

  • Tubs are trued to original specification, acid dipped and e-coated to protect against corrosion.

  • Alloy frame and safety cage are welded to the tub, reinforcing the chassis. 

  • Carbon fiber laminate assemblies, bonded to the chassis, replace original steel body panels. The result is an extremely rigid and lightweight chassis, capable of handling race stress loads.​
