These adaptation bars are designed to bridge the gap between Corbeau base-mounted reclining seats with a 291mm bolt pattern and Sparco sub-frames that use the wider 345mm bolt pattern. They provide a secure and precise mounting solution, allowing you to fit Corbeau recliners directly onto Sparco or other aftermarket frames without drilling or modifying the seat base.
Manufactured from high-strength steel, each bar is accurately drilled and spaced to align perfectly with both mounting patterns, ensuring a reliable fitment that maintains correct seat positioning and safety. Ideal for custom installations or mixed-brand setups, these bars make it easy to integrate your Corbeau recliners into vehicles using Sparco-style sub-frame layouts.
These are not car-specific; we recommend professional fitment of all subframe equipment.
Pricing: Product pricing is for 1 adaption kit for 1 seat.
