Surpassing the stringent demands of the FIA 8862-2009* Advanced Racing Seat standard, the 129 series is Racetech’s no compromise professional motorsport seat.
There is none better when it comes to comfort and safety.
This is our lightweight Kevlar/carbon version, one of the lightest seats in the world to achieve 8862-2009 homologation!
Side and back* mounting brackets are included.
* To comply with FIA 8862-2009, the 129 series seats must be back-mounted to the rollcage at shoulder level.
Back-mounting can be achieved in a variety of ways, but for some basic guidelines, see instructions here.
Back-mounting improves seat strength and stability during an impact, increases driver 'feel' and reduces driver fatigue, see the explanatory video here.
