Here I will overview the installation of the T3 seat rails (https://technotoytuning.com/toyota/ma60/racing-seat-rails-ma60-supra) into our cars since instructions are not provided. There are a few way to go about it as well as some slight mods that may need to be done to make the rails fit nicely.

Step one: Figure out what orientation you need the rails to be at. The rails themselves are a mirror image of each other and can thus be mounted interchangeably like so.





This is to allow for the wide variety of racing seats on the markets to fit as dimensions are different across many of them. The top picture works for narrow mounted seats and the bottom picture for wide mounted seats. The easiest way to figure out which orientation to use is to bolt the side brackets to the seat (Go to Step three for instructions) and measure from bracket mounting hole to adjacent bracket mounting hole, and match the measurement roughly to the mounting points on the rails in the car.

Step two: Bolting the brackets down and mods that may be necessary to do so. First off, the driver side bracket will be parallel to the door sill, but no matter what, the passenger side rail will never be completely straight and sit slightly angled like this    l \    looking from the top down, but not as drastic as the slash lol. This is not an issue as the rails have a lot of adjustment. Bolt the drivers side rail in, done. Easy peasy. The passenger side is where we will run into issues, or at least I did.

What to do. The passenger rail is a tight fit for either orientation, and here is what you can do to get it as close to the trans tunnel which is what you will want. On the picture below in the yellow circle, cut away or move any carpet and insulation out of the way so you can put the leg with the bolt hole as close to the trans tunnel, metal to metal, so you can get the bolt through and to get the best fit. Tighten that bolt down and you will see the next issue. In the red circle below, the mount point does not line up and you will not be able to get a bolt in. So what you do to fix this is add a 1/16 or 1/8 inch washer underneath the front mounting point to move it forward enough to gain space to get the back bolt in. Done right? Wrong. Once you have both rails mounted down, place your bucket seat on the rails. You'll see that it wobbles as it does not sit flat and if you bolt it down and force it, it will put tension on the frame of the seat, forcing it to flex which you do not want. Solution, add another 1/16 or 1/8 inch washer, but this time under mounting point in the red circle, whichever levels the seat better, after that, everything starts to fall into place. If you have the rails set up for narrow mounting, tighten the bolts down. You are done with this step. Continue below for wide mounting.



Here is what you need to do to fit the passenger side rail for setups using the wide orientation (like me!) Like above, the washers still apply, but the issue that we face now is that the passenger rail in this position fits really tight along the trans tunnel and you may have a hard time getting the bolts in the front mount point and trying to get it fairly nice and parallel. In the picture below, where the red rectangle is, move the carpet back and you will see wires in the way for the seat belt light. Tuck the wires as high as you can out of the way and it should give you enough room to bolt the rail down with a snug fit along the trans tunnel, and the yellow circle below is a piece of plastic trim that may get in the way when you try to tuck it close, just pry it up and out of the way a little bit, doesn't need much. Once you position it to your liking, tighten everything down and you are done with the seat rail part of the install.



If you did it right, you can get the wide setup pretty parallel like so. On the narrow set up, the passenger rail will never be completely straight, but like I stated earlier, it shouldn't be an issue, may bug you if you have OCD though haha.



Step three: Bolting the seat to the side brackets, and bolting the complete assembly onto the rails. Side brackets are pretty simple, but I'll tell you the order in which the hardware mounts onto the seat (use T3 hardware as it is the correct length). In order from start to finish: allen head bolt, washer, side bracket, nylon puck, and the seat. Position the seat in the car and place it on top of the seat rails, plop your ass in the seat and spend the next hour pulling the seat in and out of the car and moving the adjustment of the the seat up or down on the side bracket slots till you find where you want the seat positioned comfortably lol. Once you've figured out roughly where you want the seat, find the easiest spot to slip one of the bolt and nuts loosely into the front sliding portion of the side bracket and seat rail to keep the seat from falling back or somewhat in place so you can get started on putting all the other mounting hardware on. This is the order of the side bracket to seat rail mounting hardware: allen head bolt, small metal washer, nylon washer, side bracket, nylon puck, seat rail, big metal washer, lock washer, and nut. Once you have all of them started, go back to the first bolt you put in just to keep the seat up and add the rest of the hardware on. Have fun for the next hour cussing and trying to get all the washers and nuts on blindly under the seat, and if you have big hands, I wish you luck. Here's what your blood and sweat will reward you with.





Feel free to ask me any questions if you end up getting these.

Damn Jonny, nice write up (other than some minor editing from a grammar nazi - LOL).  Derek needs to sticky this one to the write ups section.
I assume this would work with MA60s, my Corona, and 2nd gen Celicas as well?

Thanks Bob! And I know hahaha :heh: Did this during my down time between jobs at work, so sorta sped through it. Well, since these were originally made using a MA60 as the template, I would hope they work lol. I don't know first hand, but if the Corona and 2nd gen Celi have the same seat mounting points as the third gen, I would highly assume so!
