STRADIAIII has a newly designed monocoque body shell with a bone frame and ZETA IV designed by 3D-CAD. The seat rigidity and strength of STRADIAIII have been greatly improved compared to STRADIAII. In addition, its newly-developed reclining mechanism and one-touch reclining lever, which aim at maximal operability, convenience, and durability, achieve more reliable holdability and comfort by suppressing backlash and vibrations through stepwise adjustments.

What's more, a belt hole for a 6-point harness has been newly installed on the back of the seat, which uses a specially designed high-density urethane foam for its seat and thigh cushions. STRADIAIII is a new-generation reclining seat that combines the holdability required for circuit driving with the convenient and comfort required for everyday use at a high level.

Features:

• A new frame & shell designed using 3D-CAD
• A newly developed stepped reclining mechanism
• A one-touch reclining lever with excellent functionality
• Utilizing the LOWMAX System which enables the maximum low driving position

Specially designed seat and thigh cushions

The specially designed, high-density foam molded urethane used for the seat and high cushions applies body pressure evenly to the flat seat surface in order to provide a strong hold and reduce fatigue. What's more, it does not easily squish and has excellent durability. In addition to the standard type, a low-type thigh cushion with a thickness reduced to 2/3 is also available.

Belt holes compatible with an FHR system and 6-point harness

A large-diameter belt hole compatible with FHR systems such as HANS, as well as a 6-point harness belt hole, which has often been requested by STRADIA users, have been newly-installed at the bottom of the seat. This allows drivers to enjoy circuit driving and various other motor sports in greater safety.
