So I got a set of BRIDE ZIEG IV WIDE seats and I am having a hard time getting any info on what seat rails I need. I am located in Canada and the distributor I found is horrible on getting back to people. I am trying to mount them into an FD3S I would like the passenger side to be fixed in spot and the drivers side I have not decided on weather or not I want it to move. I would like to stay with a bride mounting system just to keep everything the same if its not possible that fine also. Any help would be great!

 

try Pete at Nextmod .... 7634 Woodbine Ave, Markham, ON L3R 2N2

That's a great looking seat!
I have been eying one for my passenger side to accompany my Xero RS driver side (not sure of the full updates on the plus model?)
Looking forward to seeing how it turns out for you


I have a strong feeling this seat is going to clear everywhere if we get you the right seat mount


Bride doesn't list the Zieg Wide as an applicable FD option, but suggests a Super Seat Rail LF for the Zieg series (reference R039LF Right) and a Super Seat Rail IG (reference R039IG Right)



FWIW, I found the Bride FX FIA fixed seat mount (on the left below) was absurdly tall on my seat compared to using my fixed mount from Adam Griffith (one piece on the right below)













Compared to my seat, your Zieg Wide is 5mm narrower at the shoulders but 10mm wider at the base (what I'd really appreciate on my driver side!)




All's that to say, your seat is 20mm shorter than mine and the headroom was the issue with the FX rail

I can't say for certain, but I don't think the FX fixed rail will work for you either






Unless the IG (the fixed rail of Bride's two Zieg series recommendations) is at least an inch shorter than the FX (if JRP can get you accompanying height with the breadth and length dimensions), I would look for another fixed rail option

Sorry this isn't as definitive as I can be for you, but this might help you with a process of elimination
