Bride RO Super Seat Rails - Part 2 Installed

Found some free time to install the Bride RO seat rails during the Raya hols. Installation was DIY with help from Tao. Before installing I took the opportunity to weigh the stock mild steel and titanium seat rail fasteners. Stock.


This means a weight saving of 12 grams per set of fastener (bolt + washer). There are 8 sets of fasteners (4 per seat rail) hence the savings are approximately 96 grams.

Uninstalling the Recaros and H Performance seat rails lead to some not so nice surprises. First surprise is the use of these large mild steel washers to level the seats. Four are used per side of a seat/seat rail. If you're wondering what the wire is for, it's for the "fasten your seat belt" warning light which I no longer use :)

If you are still using the stock dash, make sure the wire is connected to this wire which in turn is connected to the seat rail. If you don't the seat belt warning light will be permanently lit.

Decided to weigh the washers for kicks. Total weight savings together with the seat rail bolts are bout 0.23kg.

The washers are required due to the poor manufacturing tolerance of the H Performance seat rails. These actually incorporate genuine Recaro sliders but IMHO that is the only positive aspect of the seat rail. Picture below of the H Performance seat rail after removing the Recaro.

There is no bridge plate in between the sliders for greater structural strength like the Bride RO. Which is not surprising or should I say shocking as what I found out next when disassembling my Recaro from it's seat rail. Each Recaro SR4 utilizes six M6  x 25mm bolts to secure it to it's seat rail (Front uses 4 and rear 2). Only four bolts were used for my case. This was consistent for both seats. Different fastener heads and length were also used instead of one standard type. Some M8 sized spring washers were even used for an M6 bolt I kid you Not! What you can't see can't kill you right? How much does 12 sets of properly sized and load rating mild steel fasteners (bolt and appropriately sized washer) cost? Can't be more than a couple ringgit. Picture below of the crap fasteners used by H Performance.

Picture below shows the Bride RO vs H Performance seat rail.

The Bride ROs weigh 5 kg each while the H Performance seat rail is 4kg which unfortunately means 0.75 kg of flab is added to Sharkie. If you value your own personal safety this is a compromise I am more than happy to accept. Picture of the new seat rail and seat mounted back on Sharkie. 

Seat height with the Bride RO is approximately 20mm lower than the H Performance seat rail which is perfect for me as I'm not your average height Malaysian. Rail sliding action is very positive. Seat belt buckle no longer does the disappearing act. 

Overall I am very satisfied and impressed with the quality of the Bride ROs. My only regret is I should have gone with these seat rails when I got the Recaros two years back.
