Racetech RT4119 HRW Racing Seat

The Racetech RT4119 HRW is a serious containment seat for serious cars. Built around Racetech's proven 4100 shell geometry and adding integrated head restraints, this seat is aimed squarely at high speed track and endurance use where lateral support and side impact protection matter.

Why we like the RT4119 HRW

• FIA 8855-1999 approved with extended head and shoulder support for modern safety standards
• High rib and torso bolsters that lock you in place under heavy braking and long high g corners
• Carefully shaped head restraints that work well with HANS style devices and do not crowd the helmet when sized correctly
• Composite shell balances stiffness and weight for club and pro level builds
• High quality fire retardant trim with replaceable cushions so you can fine tune ride height and leg support
• Designed to work with Racetech side and back mounting hardware for a very rigid install

Fitment and sizing

This listing covers the HRW narrow and short variant of the RT4119. It is ideal for drivers who want a compact shell with full head containment. As with all race seats, choosing the correct size is critical for comfort and protection, so if you are unsure on measurements, get in contact and we can walk you through the sizing chart.

Installation notes

To achieve the intended level of protection, Racetech recommends using approved side brackets and a back mount tied into the roll cage or chassis at shoulder height. Make sure your harness angles, helmet clearance and steering position are all checked with the car at ride height before final drilling.
