Surpassing the stringent demands of the FIA 8862-2009 Advanced Racing Seat standard, the 129 series is Racetech’s no compromise professional motorsport seat. Adept at cradling Bathurst winners and most of the V8 Supercar competition, there is none better when it comes to comfort and safety. This is our fibreglass (GRP) version offering great strength and safety benefits but at a reduced price. CAD models are available on request. Side (RTB1009M) and back (RTB1006B) 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 improves seat strength and stability during an impact, increases driver 'feel' and reduces driver fatigue, see the explanatory video here.
