Original Recaro Germany seat rails cost a bomb (2K upwards for a pair of seat rails) so I researched for lower cost but similar quality alternatives. Short of repeating myself to death, one knows that aftermarket seat rails for the Slowtra are not exactly in abundance and that such research typically ends up in a dead end. However for once the Gods of Car Mods were smiling on me and the research led me to conclude that a N16/B15/G10 uses the same seat rails as a JDM B15 Sunny and when it comes to Jap cars, Bride is the most popular and well known brand for seats and seat rails. And Bride does have a seat rail application for the B15. Part number of the Bride seat rail for JDM B15 Sunny.
As can be seen above, Bride has multiple seat rail models but these are meant for their varied range of seats or side (vs bottom mount) for full bucket single piece competition seats. Only the RO and MO models fit my Recaro SR4. I decided to bite the bullet and order the RO as this can later be upgraded to MO type by buying and installing the optional MO adapter plates on the RO seat rail. I was initially going to order from RHD Japan but pondered and procrastinated on this for ages. More than a year in fact as I was very concerned about the taxation costs. In the end Bro Eu Jin came to my rescue and sourced the RO seat rails for me. Bro Eu Jin is the boss of JDM Auto Link and he can get any JDM part you want so look the man up!
Price of a pair of seat rails came up to more than 1.5K MYR direct to your doorstep. Price will differ according to the exchange rate of the Japanese Yen vs Malaysian Ringgit so best to check with Eu Jin. Lead time between placement of order and deposit and arrival at one's doorstep is between 1 to 3 months depending on the shipment schedule between Japan to Bolehland. If you want fast you can always order from RHD Japan and airfreight to your house but good luck in between. Picture of the shipping packaging.
Part number and application. Looks like the Y11 Wingroad also use the same seat rail.
The seat rail. Also included is a detailed and idiot proof installation "manual" complete with drawings. No knowledge of Japanese is required to know what goes or fits where. Also included is a Bride seat rail specific anchor bolt for the seat belt buckle. Only one anchor bolt is supplied per seat rail so don't lose it.
Be careful of fakes when it comes to Bride seats or seat rails. I have seen many. A seat and it's seat rail is a major critical safety component of any car so you decide if you wanna mess around with that. Original Bride seat rails uses slider rails sourced from Faurecia in France. Faurecia oems for PSA (Peugeot and Citroen), Nissan, GM and Volkswagen so they definitely know what they are doing. The upper rail metal thickness is 2mm while the lower rail is 2.3mm. Beefy!
I also decided to replace all the seat rail fasteners with titanium equivalents. You will need six M6 X 25mm bolts to secure each SR type seat to its seat rail meaning 12 total unless you only have one seat. Likewise four M10 X 30mm bolt secures each seat + seat rail to the car (8 total). Don't forget the washers.
Took me forever to find a M10 X 25mm diameter washer for the bolt securing seat rail to car. Standard diameter for a M10 titanium washer is 20mm. 20mm diameter might have insufficient surface clamp area as the bolt hole on the seat rail is way larger than 10mm to allow for some adjustment. In the end the closest I could find is a 30mm diameter washer from Allied Titanium in the US.
Stay tuned for Part 2 where I install the seat rails.
