Racetech Lowback Series

Racetech offer the innovative Lowback series as a solution for boats, kit cars and custom-shop fabricators. Using the established 1000 and 4000 seat we remove the head support making this series ideal for fitting into low cabins or as an alternative for classic cars where FIA homologation is not required. The Cobra seat is a little different, and was originally designed for use in AC Cobra replicas. The Cobra is base-mounted, alleviating the need for side brackets.

Suede Wear Patches

Suede leather wear patches are sewn into those areas on the seat which can wear over time with regular use, especially during entry and exit of the seat. The grippy nature of the leather also helps to hold the driver’s body in place.
