From the original writeup:
Well, I finally did it. And it's well worth it! (Even just sitting in my car ... )
I also helped Mark Scire with his ///M Coupe yesterday so we could test in an operational car (mscire2). It makes the seat feel completely awesome. No longer are you spit into the dash / steering wheel when braking. Additionally, you are held back into the seat better, and the additional leg support is very nice.
I've always complained like an old man that my back hurt after driving for extended periods. Only happened when driving the coupe. I THINK this is the culprit and this should aid solving it!
One of my gripes about how others have done this in the past is how a bolt was used instead of a stud / nut combo for the front of the rail. Not only is it a pain to assemble that way without a stud, it puts too much strain on the bolt head due to the slight angle of the rail.
To the drawing board!
I was able to properly source grade 10.9 and 13.9 hardware (gotta use the best quality).
Using hardened metric couplers, hardened studs and hardened washers, I developed an OEMish mounting system that accomplishes the seat incline, all with better than OEM grade hardware (woohoo!). I'm attaching my diagram and installation instruction to this post.
Overall, a rather helpful, low-cost, quick project with real benefits!
Pictures as requested!
This modification is done at the risk of the modifier - Do this only at your own risk!
I'm assuming that this is for both driver and passenger seats. And is this the 1 inch or 3/4 inch rise? I guess either way, put me down for 2!
Mr. T:
Thank you for posting the photos of the hardware in place. I have your kit, yet to be installed, and I find the pix very, very helpful- I am, after all, primarily a visual kind of guy.

I bought this kit and it is 100% worth every penny.
Mods: Remus 76mm exhaust, CDV delete, ASA AR1 18in staggered wheels, Turner 12 mm spacers, custom red tails, Kenwood deck/Sirius/BT/USB, ZHP knob, Redline boot, LeatherZ armrest, Amsoil all around, red needles, Akebono Euro brake pads, 34k original miles!
Several of us had a chance to sit in Jon's car which had the seat tilt modification performed. It without a doubt improved the seating comfort 10-fold.

Payment for 2 kits and PM sent. Thanks.
Total rise is just shy of an inch when I last measured installed.
No problem! Hope you get it installed soon.
Thanks, I thought so too! Since buying my new coupe I've already started griping about the seats.
Which Jon?
You are welcome.
Very, very simple. Takes a maximum of 30 minutes per side but that's only if you are struggling to find the right tools. Mark and I accomplished doing this to his Dad's roadster in less than 10 minutes.
OK - I'll look for the $20 in my PayPal. I did have to send out a few emails asking for shipping addresses, so please respond if you got one.
Thanks!

Jonathan, b/c I'm lazy and don't want to take get crumpled into the car in my garage, what length studs / couplers are you using? Being vertically challenged, I'd like to reduce my tilt by 1/2 - 1 cm... since I need to move the seat forward a bit, the tilt gets VERY exaggerated. I'd rather just order the right size stuff instead of grinding what I have.
You can reduce by about 5mm and still get appropriate engagement of threads in the coupler. Anything > 5mm and it's questionable. Look in the last seat mod thread (sorry, at work now). I have the length measurements somewhere in there. I'm still trying to find the right parts to make a "shorty" kit. I can get shorter studs - that's no problem - but I'm having trouble finding appropriate couplers.

I'm in... sending you paypal now
Good stuff. This was one of my main complaints about the stock seats.
Got it. Will ship today.
Yep, they don't have the right stuff or shorter lengths. It seems that 1" or longer is standard, so yeah, that's not going to work. For shorty kits, the coupler will need to be ~20mm long.
Yep. Except for the fact they weight 2 tons each. I wish I could get aftermarket seats in my car that fit my "big bones". LOL.

Any issues with shearing those bolts if you happen to get yourself into an accident?
