What makes the STRADIA III REIMS different from the standard STRADIA III?

The REIMS is a variant of the STRADIA III that features full coverage in a high-quality suede-like fabric with chic color line accents in three combinations; black and black, black and blue, and black and red. The underlying seat engineering, frame, shell, reclining mechanism, LOWMAX System, and cushion options are shared across the STRADIA III range. The REIMS represents the premium upholstery and aesthetic direction within that lineup.

How much stronger is the STRADIA III frame compared to the STRADIA II?

The STRADIA III's newly designed bone frame and monocoque shell deliver a 200% increase in load capacity, a 40% improvement in torsional strength, and a 15% increase in backrest frontal collision strength compared to the STRADIA II. These improvements were achieved through a complete redesign using 3D-CAD, with the shell geometry drawing inspiration from the ZETA IV.

What is the LOWMAX System and how does it benefit the STRADIA III REIMS?

The LOWMAX System is a BRIDE-patented technology that achieves a low seating position even in compact interior spaces, and allows precise alignment of the steering wheel and seat centers to eliminate positional offsets. In the STRADIA III REIMS, this means drivers can achieve the correct driving posture and maximum control regardless of the vehicle's interior dimensions, which is particularly relevant for smaller or lower-roofed vehicles where standard bucket seats may sit too high.

Is the STRADIA III REIMS compatible with FHR systems and 6-point harnesses?

Yes. The STRADIA III REIMS includes large-diameter belt holes compatible with FHR systems such as HANS, and a newly added 6-point harness belt hole at the bottom of the seat. Both features are included to support drivers who compete in circuit racing and other motorsport disciplines where advanced restraint systems are required.

What cushion options are available for the STRADIA III REIMS?

Two cushion options are available; a standard type and a low type. Both use high-density foam molded urethane for even body pressure distribution and compression resistance. The low-type thigh cushion has a thickness reduced to two-thirds of the standard type and suits drivers who prefer a lower cushion profile or need a reduced seating height within their vehicle.

What seat rails are compatible with the STRADIA III REIMS?

The STRADIA III REIMS is compatible with the LR, RB, RK, and RO type seat rails. All compatible rails are sold separately. Vehicle-specific rails are required for installation and the appropriate rail type should be confirmed for the specific vehicle before purchasing.

Does the STRADIA III REIMS have a seat sensor and is it compatible with all vehicles?

Yes. The STRADIA III REIMS is fitted with a seat sensor in the seat area. However, the seat sensor may not be compatible with some vehicle models. Buyers should confirm sensor compatibility with their specific vehicle before purchasing, particularly if the vehicle uses an occupancy sensing system tied to airbag deployment or warning indicators.

Description

BRIDE STRADIA III REIMS Reclining Bucket Seat

BRIDE’s sporty reclining seat, designed as a semi-bucket seat, offers high rigidity and support that rivals a full bucket seat, while enhancing ease of entry and exit. The STRADIA series, which has undergone its first complete redesign in nearly 15 years, represents a new generation of reclining seats. Developed with BRIDE’s vision to blend the holding performance required for track driving with the comfort and practicality needed for daily use, the STRADIA seats feature innovations from the design and body shell to the frame, cushion, and reclining mechanism. This flagship model draws on BRIDE’s 40 years of expertise and experience in motorsports.

The STRADIA Series

A New Frame & Shell Designed Using 3D-CAD: The newly developed bone frame and monocoque body shell, inspired by the ZETA IV design, are specifically shaped to provide greater shoulder support, significantly enhancing hold performance. This redesign has increased the frame’s load capacity by 200%, improved torsional strength by 40%, and boosted the backrest’s frontal collision strength by 15% compared to the STRADIA II.
A Newly Developed Stepped Reclining Mechanism: The reclining mechanism has been updated for a more compact design, delivering improved precision and strength. Backlash and looseness, common in stepped adjustment mechanisms, have been minimized to ensure more reliable holding and increased comfort.
A One-Touch Reclining Lever with Excellent Functionality: In the STRADIA III, BRIDE replaced the backrest angle adjustment dial with a one-touch reclining lever, improving ease of use, durability, and space efficiency inside the vehicle.
Utilizing the LOWMAX System Which Enables the Maximum Low Driving Position: The STRADIA series utilizes BRIDE’s patented LOWMAX System technology, which enables a low seating position, even in compact spaces. This system allows for precise alignment of the steering wheel and seat centers, eliminating offsets and ensuring maximum comfort and control.

The STRADIA III REIMS

BRIDE’s latest flagship model offers a new generation of reclining seats, combining superior holding ability with convenience. Available in three color options—gradation logo, black, and red—the seats also come in two shell types: FRP silver shell and super aramid black shell. Cushion options include both standard and low-type cushions. The STRADIA III model, a high-performance reclining seat with excellent support, now features a fully redesigned skin and is upholstered entirely in high-quality, suede-like fabric.
- Specially Designed Seat & Thigh Cushions: Specially designed seat and thigh cushions use high-density foam molded urethane to evenly distribute body pressure across the flat seat surface, providing strong support and reducing fatigue. The material resists compression and offers excellent durability. A low-type thigh cushion, with a thickness reduced to two-thirds, is also available as an alternative to the standard type.
- Belt Holes Compatible with an FHR System & 6-Point Harness: The seat now includes large-diameter belt holes compatible with FHR systems such as HANS, as well as a newly added 6-point harness belt hole at the bottom of the seat—an addition often requested by STRADIA users. These features ensure greater safety for drivers participating in circuit racing and other motorsport activities.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
