"Beyond the Limit: Experience Ultimate Connection with HPI FIA-Certified Racing Harnesses"
Once you have perfected your cooling system and mastered engine thermal management, the next step is preparing yourself to become truly connected to your machine. Whether you can push the accelerator with full confidence on the circuit depends entirely on how securely and stably you are seated.
HPI’s racing harnesses and floor bars are designed to support your drive with reliable safety and the ultimate hold.
1. Reliability and Precision: FIA-Certified "Safety" and "Operability"
Why do top drivers choose HPI? It is not just about holding power—it is about the flexibility required to react instantly under the extreme conditions of a circuit.
World-Class Trust: FIA-certified models recognized in competitions both in Japan and overseas. Because these are pieces of equipment you trust your life with, we maintain uncompromising quality.
Engineered for Performance: Designed to minimize body movement while allowing for quick, precise strap adjustments, ensuring drivers can focus entirely on their driving line.
The Ace’s View: Uncompromising Trust Brought by FIA Certification
"Many drivers think a harness just needs to hold them in place.
But to shave down lap times in the extreme conditions of a circuit, you need 'flexibility' that doesn't hinder split-second decisions and operations. HPI's lineup includes FIA-certified models. Because this is equipment you entrust your life to, our development team maintains uncompromising quality."
2. Seamless Installation Without Modifications — The Definitive Benefits of Floor Bars
When installing a harness, many drivers worry about modifying the vehicle body.
HPI eliminates that hurdle with original ideas.
No Vehicle Modifications Required: This floor reinforcement bar allows you to attach seatbelts without modifying the vehicle body.
Simultaneous Chassis Rigidity Enhancement: By running floor bars across the left and right sides of the driver and passenger seats, vehicle rigidity is increased. It not only securely anchors the seatbelts but also brings the secondary benefit of improving body rigidity.
Smart Installation and Dedicated Design: For the shoulder belts, you can use the factory seatbelt mounting bolt holes of the rear seats. These are vehicle-specific masterpieces born from our deep familiarity with the floor layouts and body structures of iconic cars that HPI has worked with for years—such as the BNR32, S15, GR Yaris, and R35.
Note for Competition Use: When competing, please use in accordance with various regulations.

Drivers' Impressions
We received genuine impressions from users who enjoy HPI racing harnesses and floor bars, ranging from circuit runs to everyday driving. Thank you for your cooperation.
🚗Toyota 86 (ZN6) Owner:
"During hard cornering on the circuit, my body is firmly fixed to the seat with zero play. Body movement caused by G-forces used to be a problem, so I am really impressed by this! Installation used existing bolt locations and the floor bar, so I didn't need to modify the vehicle side and managed to do it myself, which was a huge help. Thanks to the floor bar, there is a solid sense of security, and the belt itself has good thickness. The solid 'click' feeling when tightening is completely different from cheap products. Safety is a given, but operability and the solid feel of the body have improved so much that I'm really glad I made this choice."
🚗Nissan Silvia (S15) Owner:
"The floor bar is truly a welcome feature because it allows the harness to be securely anchored without any body modification. Running the bars across the left and right increases the solidity of the chassis, so the sense of security during sports driving is totally different. Also, being able to release the buckle smoothly without it snagging is quietly the best part. Because you can choose colors, it's a plus that it's easy to match the interior atmosphere. The stitching is quite neat, and I've been using it pretty hard with zero sagging or fraying so far."
🚗Honda Civic (FK7) Owner:
"It restrains the body securely, yet there is no strange sense of pressure while driving. It doesn't feel overly restrictive, and the body adapts naturally. The introduction of the floor bar was also a smart bolt-on installation, and not having to worry about modifications was great. The buckle can also be released intuitively with a click, so stopping by a convenience store isn't a hassle at all. Honestly, it's a product that thinks more about the user's side in actual practice than what's just written on the catalog specs!"
