Racetech RT9119 Lightweight Racing Seat | Carbon Kevlar

The Racetech RT9119 Lightweight Racing Seat delivers professional motorsport protection, exceptional driver support, and lightweight carbon/Kevlar construction for demanding circuit racing applications. Developed from Racetech's proven 129 Series racing seat design, the RT9119 combines advanced composite materials with integrated head restraints, ergonomic body containment, and a structural back-mounting system.

With a shell weight starting at just 9.9 lbs (4.5 kg), the Racetech RT9119 provides a lightweight alternative to conventional composite racing seats without sacrificing the supportive geometry demanded by competitive drivers. Its carbon/Kevlar hybrid shell, energy-absorbing padding, and integrated lower-back ventilation make it an excellent choice for sprint racing, endurance competition, and professional track applications.

Available in Standard, Wide, Tall, and Wide & Tall configurations, the RT9119 accommodates a variety of driver sizes. The Standard, Tall, and Wide & Tall versions are homologated to FIA 8855-1999 when installed according to Racetech's approved mounting requirements. The Wide RT9119WHR model is not FIA homologated.

Lightweight Carbon Kevlar Racing Seat with Professional Driver Protection

The Racetech RT9119 builds on the ergonomics of the company's 129 Series racing seats while using a proprietary carbon/Kevlar hybrid composite shell to reduce overall weight. The result is a rigid yet carefully engineered racing seat designed to support the driver during high lateral loads and demanding motorsport conditions.

Integrated head restraints and high-density energy-absorbing foam help provide lateral support around the driver's head and torso. Racetech's distinctive shoulder and backrest geometry is designed to work with compatible racing harnesses and frontal head restraint systems.

For endurance racing, the RT9119 features an integrated air duct that can direct cooling air toward the driver's lower back when connected to a compatible ventilation system. Removable back and base cushions also allow drivers to fine-tune fitment and comfort.

The lightweight shell is finished in a clear gel coat that reveals its composite construction, complemented by black fire-retardant upholstery and black perforated leather anti-abrasion patches.

Racetech RT9119 Racing Seat Dimensions and Fitment

Choosing the correct racing seat requires more than matching a driver's height and waist size. Hip width, shoulder width, torso length, harness positioning, and vehicle interior clearance all affect proper fitment.

Before ordering, confirm the seat's exterior shoulder width, internal hip width, overall height, mounting width, and available cockpit clearance.

Racetech RT9119 Mounting Requirements

The Racetech RT9119 uses side mounting brackets in combination with structural back mounting provisions. For FIA 8855-1999 compliance, the FIA-homologated 119 Series models must be back-mounted to the vehicle's roll cage at shoulder level.

Recommended Racetech mounting components include:

• RTB1009M: 5 mm aluminum side mounting brackets.
• RTB2115B: Aluminum structural back mounting bracket.
• RTB3115B: Alternative compatible structural back mounting bracket.
• RTB2005C: Roll cage mounting clamps, available in different sizes to match the roll cage tubing.

Important Safety Requirement: Side mounting alone does not satisfy the manufacturer's FIA 8855-1999 installation requirements for the homologated RT9119 models. The seat must also be attached to the roll cage using an approved rear mounting configuration.

Review the manufacturer's Racetech 119 Series Back Mounting Instructions before installation.

All mounting brackets, clamps, bolts, and roll cage attachment points must meet the manufacturer's requirements and the applicable racing organization's regulations.

Integrated Driver Cooling for Endurance Racing

The Racetech RT9119 features integrated air ducting that directs ventilation toward the driver's lower back. When connected to a compatible air supply, this system can improve airflow through the seat and help drivers manage heat during long racing sessions.

The removable back cushion works with the integrated ventilation channel to allow cooling air to reach the driver's lower back. This design makes the RT9119 particularly appealing for endurance racing and competition in hot environments.

A compatible air supply, ducting hose, or ram air kit may be required and is sold separately unless specifically included with the selected configuration.

Professional Motorsport Seating with Reduced Weight

The Racetech RT9119 combines the ergonomic advantages of the 129 Series with the reduced weight of a carbon/Kevlar hybrid shell. Its integrated head protection, customizable cushioning, and structural mounting provisions create a competition-focused platform for drivers seeking lightweight construction and dependable support.

From national-level circuit racing to demanding endurance events, the RT9119 provides a balance of driver containment, comfort, and lightweight motorsport engineering.
