Racetech 4000 Series

A classic design. Similar in shape to the RT1000, but slightly wider overall and with flared thigh support, this racing seat is best suited when easy access in and out of the seat is required. Also useful for applications where fitting a wider variety of body shapes is important e.g ride seats. Featuring suede wear protection in both the shoulder and thigh areas and a racing-heritage inspired quilted centre panel.

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, especially at the shoulders during cornering.

Flush Bosses

Flush bosses make installing your Racetech seat a breeze! Its easy to start the mounting bolt threads when you can see them, even when the seat is up against the transmission tunnel or against the door sill.
