BRIDE LF Super Seat Rail

The BRIDE Super Seat Rail LF Type is a Japanese-manufactured performance seat rail, designed exclusively for BRIDE LOWMAX series fixed bucket seats and engineered to deliver the deepest seat position drop available in the BRIDE rail lineup at up to 80mm below standard, subject to vehicle type. The LF Type is not a universal performance rail and cannot be used with non-LOWMAX BRIDE seats or third-party seats; it is purpose-built for the LOWMAX series and the specific geometry those seats require to achieve the full depth of the 80mm drop. Compatible BRIDE seats include the VIOS III series, ZIEG IV series, MAXIS III, and edirb models 042 and 061. The mounting dimensions are 290mm length (±5mm tolerance) x 395mm breadth, consistent with the other performance rails in the BRIDE lineup, but the LF Type’s exclusive LOWMAX compatibility means the dimensional match alone is not sufficient to determine fitment; the seat must be a supported LOWMAX model.

Utilizes Sliders Made By Faurecia Exclusively For BRIDE

• BRIDE super seat rail relies on sliders, which are an essential part, provided exclusively by Faurecia (France), one of the world‘s leading mechanical parts producers
• The sliders boast 2.0mm thick upper rails and 2.3mm thick lower rails. With a 10 mm pitch and a slide amount of 220 mm, they lock on both the left and right sides, don‘t shake, and have remarkable strength and longevity.

ASEA-Approved High Quality & Peace of Mind

• This product, the Super Seat Rail, has been officially approved by the ASEA and has successfully met the requirements of this Japanese motorsports industry organization, which consists of motorsports companies, manufacturers, and retailers of tuning parts.

Frequently Asked Questions

• What seats is the BRIDE Super Seat Rail LF Type compatible with? The LF Type is exclusively compatible with BRIDE LOWMAX series fixed bucket seats: the VIOS III series, ZIEG IV series, MAXIS III, and edirb models 042 and 061. It is not compatible with non-LOWMAX BRIDE seats or any third-party seat models. The mounting dimensions alone are not sufficient to confirm compatibility; the seat must be one of the listed LOWMAX series models.
• Why is the LF Type exclusively for LOWMAX series seats? The LF Type is engineered specifically around the mounting geometry and structural requirements of BRIDE’s LOWMAX series fixed bucket seats. The LOWMAX system is a BRIDE-patented design that achieves an ultra-low mounting position through a specific shell and seat base geometry. The LF Type is developed to work with this geometry to deliver the full 80mm drop; using it with a non-LOWMAX seat would result in incorrect fitment and would not achieve the intended position reduction.
• How much does the LF Type lower the seat position? The LF Type delivers a super low seating position of up to 80mm below standard, the deepest drop available across the entire BRIDE performance rail lineup. The actual reduction achieved is vehicle-dependent and the maximum 80mm is not guaranteed across all fitments. Buyers should confirm the achievable drop for their specific vehicle before purchasing.
• How does the LF Type compare to other BRIDE performance rails in terms of position drop? The LF Type’s maximum 80mm drop is significantly greater than any other rail in the BRIDE lineup. The FG, IG, FK, and FB Types all deliver up to 50mm, and the FO Type reaches up to 30mm. However, the 80mm capability is only available when using a compatible LOWMAX series seat; the LF Type cannot be used to achieve this drop with non-LOWMAX seats regardless of dimensional compatibility.
• Can the LF Type be used with the ZIEG IV? Yes. The ZIEG IV series is listed as a compatible seat for the LF Type. The ZIEG IV uses the BRIDE LOWMAX system and falls within the supported LOWMAX series for this rail.
• What are the mounting dimensions of the LF Type rail? The LF Type has mounting dimensions of 290mm length with a ±5mm tolerance and 395mm breadth, consistent with the other BRIDE performance rails. However, unlike the other performance rails, these dimensions alone do not confirm compatibility; the seat must be a supported BRIDE LOWMAX series model for the LF Type to be the correct rail choice.
• Is the BRIDE Super Seat Rail LF Type made in Japan? Yes. The LF Type is manufactured in Japan to BRIDE’s quality and fitment standards, consistent with the domestic production approach applied across the BRIDE seat and rail lineup.
