Features
N SPORT LS9 Side-mount 3 × 3-position Seat Rail
A side-mount seat rail with linear sliders and nine (3 × 3) possible height combinations in total.
- Designed for full bucket seats and other side-mount seats.
- In addition to the height adjustments with side stays and the three adjustments located at the front and rear of the seat, offering nine possible height combinations, the seat height and seat angle can be adjusted almost infinitely within the range.
- Models equipped with the S6 seat rail can be fabricated with LS9 seat rail.
- Ideal for vehicles with ample floor space offering a high degree of freedom in position selection.
- The adoption of linear sliders and the elimination of slider strain due to welding heat distortion results in sliding action equivalent in quality to original equipment. The sliders and frame are secured with rivets.
- The entire adapter also serves as a seat belt buckle stay. This increases strength, contributes to weight reduction, and reduces the offset from the steering wheel center.
- The general-purpose side stays accommodate many seats.
Detail
Sliding action equivalent in quality to original equipment
Welding heat is the primary cause of slider hardening. The mounting frame and sliders of this model are secured with rivets to avoid thermal distortion of the metal sliders. Direct welding of sliders is performed only as an auxiliary process to minimize the number of spot welds. The elimination of distortion due to welding heat and the adoption of linear sliders results in exceptional sliding action equivalent in quality to original equipment.
Weight reduction and reduced offset from the steering wheel center
The adapter* doubles as a seat belt buckle stay, so in effect it serves as a “large seat belt buckle stay.” In addition to offering increased strength and reduced weight, it is designed to be centered on the floor because the seat belt buckle stay is not installed separately. This reduces the amount of steering center offset on the door side resulting from to the configuration of the vehicle floor.
* For models requiring relocation of the seat belt buckle, it can be transferred to the adapter that attaches to the side stay. If the seat belt buckle is low (or high) relative to the seat after relocation, use the Seat belt mounting bracket extension.
In addition to the height adjustments with side stays, three height adjustments located at the front and rear of the seat offer nine possible height combinations. The elongated and diagonal bolt holes allow the seat height and seat angle to be adjusted almost infinitely within the range.
In addition to the height adjustments provided with the side stays, the combination of bolt holes — one located at the front and rear of the slider adapter and three at the front and rear of the side stay adapter — provide three height settings each. The elongated and diagonal bolt holes provide almost infinite adjustment within the range.
Because the height is adjusted with the side bolts, no extra load is applied to the sliders even when the front and rear are set to different heights. The sliders maintain smooth action when the seat is set to any of the nine (3 × 3) possible combinations of seat height and seat angle.
The general-purpose side stays accommodate many seat models.
The bolt holes used for mounting the seat itself are cut into elongated and diagonal shapes. In addition, the bolt holes for attaching to the sliders are elongated, which allows for mounting of many seat models. Moreover, in addition to offering fine adjustment of seat height and seat angle, this seat rail provides lateral seat adjustment to the left and right. It is also compatible with seats with a high bolt-hole mounting position,* such as the Recaro RS-G. In addition, weight-relief holes are provided for maximum weight reduction.
* For seats with higher mounting positions at the rear, only the bolt holes at the top of the side stays can be used.
Includes seat-mounting bolts.
All bolts required to mount the seat are included. Your current seat can be mounted only with these bolts.
Super-low-profile model
For vehicles requiring a low seating position, such as sports cars, we offer a Super-low-profile model that is a lower-profile version of the Standard model. As the driver’s hip point approaches the center of gravity of the vehicle, the driver experiences more accurate feedback from the car, such as vehicle handling and road conditions.
side airbag canceller.
Vehicles equipped with side airbags require a separate side airbag canceller to prevent warning lights from illuminating. There are 6 types, NPC001~006. Please check the matching list for the appropriate product.

Tips for mounting the seat to the side stays
Mount the seat to the side stays as oriented in the illustrations below. The installation width of the seat to be installed determines the orientation. Adjustments required to center the seat relative to the steering wheel (adjusting the seat to the left or right) are performed by changing the orientation of the side stays as they mount to the side stay mounting adapters.
Use spacers if the grommets of the belt holes interfere with the side stays, creating a gap between the seat body and the side stays.
(Adjust the number of spacers to fill the gap.)
Even if no interference occurs, a gap may be present depending on the width of the seat to be mounted. In that case, use spacers as well. (Use 30-mm bolts when using spacers; use 20-mm bolts when not using spacers.)
Note: Various spacers and bolts are included with the seat rail.

“Seat mounting width” explained
We suggest measuring the width of the seat across its bottom as shown in the image. Measure from the surfaces that mount to the side stays.
If the front and rear of the seat vary in width, measure the seat at its widest point.
