The seat is AWESOME! It won twice this year and was in contention every other time…LOL I love Racetech seats! I was once a die-hard OMP seat guy but not anymore!

Integrated Head Restraint

The 270 degree head restraint reduces lateral or oblique head movement, especially during impacts, greatly reducing strain on neck and reducing the chances of a basilar skull fracture.

Moulded Base Cushion

Keep your legs comfortably spaced and with this contoured foam cushion. Velcro fastening means that you can easily remove the cushion if you prefer to lower your centre-of-gravity and sit directly on the seat shell for a more commanding feel of the chassis beneath you.

FIA 8855-1999 Homologation

The seat is FIA 8855-1999 approved and has a 5 year lifetime. The silver hologram is an anti-counterfeit method and is applied in the Racetech manufacturing plant on completion of the seat. Note: The RT4009THR, RT4009WTHR and RT9009HR models are not FIA homologated.

Micro-adjust Bosses

Racetech 009 series seats come exclusively with four mounting bosses per side. These bosses are spaced by 90mm allowing height adjustment increments of just 10mm as opposed to 20mm on most other seats on the market.
