Agreed, neither are as useful as a suede headliner.

Good point; it would be a better point if you knew why I did it.

Civic si seats... Interesting. How hard was the install on those?

 

[CobraMarty]

These Honda Si seats are OEM quality and very similiar to Racaro seats.
The hardest was getting the sliders off the Si seats and then built a 3/8" thick steel plate adapter and then they bolted right in.

UPDATES!!!!!!!!!!!!!
My dad and I got the Civic Si seats mounted. Just gotta take them out later to drill holes for the race harnesses..
As much as I hate Hondas, they make great seats! Lol. These are extremely comfortable and supportive and I think they are acutually a little bit softer than the OEM XJ seats.

Had to remove more of the OEM Honda slider to get the driver's seat to sit lower. Turns out that the last piece of the slider was held on with 8 rivets. PER SLIDER!!! So, 16 rivets total... Those were fun to drill out.

Now I just have to do the same thing to the passenger seat eventually...

And my dad recovered the center console lid. Came out great!!

I see you have the crotch strap sitting on the floor, how are you planning on routing it? hope not over the front of the seat

 

[CobraMarty]

The Si seats are way more comfortable than the Rugged Ridge seats we put in the white jeep. The RR seats do not tilt forward, the back adjusts with a screw knob on the side, are hard and narrow. They were the same price as the Si seats and only mounted easier but that is their only advantage. It I was to do it again I would find another set of coupe Si seats and make some more adapter plates and use them.
The adapter plates are the key to the Si install
No crotch strap- mounting below the front of the seat would offer no antisubmarine prevention. Came with the 3" belts, really just wanted 3" and cam mechanism. They are yet to be mounted and the stock belt is working just fine for now.

This is a really cool project. I've always wanted to do this to a Comanche. Good luck with all the necessary fabrication.

I've got a wrx... Was thinking those seats would be nice in an xj

 

[CobraMarty]

To put any other seat in just requires an adapter plate to bolt to the stock slider bracket and then the seat will bolt to it. I used a piece of pegboard to design it. The holes with the '+' mark are for the stock bracket mounting. All the holes are 1" on center. You could figure it out, the measurements, by the picture.

AWESOME

Why use a 3/8 steel plate? You've got a lot of material there doing nothing but creating weight.

So, is this thing going to be an actual race car?

Adding weight is not because racecar.

 

[CobraMarty]

It will be an actual street legal 'racecar'. Licensed, inspected, and smoged certified. Spirited street driving, windy roads, maybe some autocross, maybe a drag race or two and a dyno toy. Not a stripped down, lightweight, non smog legal, trailer racecar/trackcar.

The 'racejeep' has rugged ridge seats, not the Si Seats with the 3/8" steel plate adapter.

The Si seats and 3/8" plate in in the Red on-offroad-supercharger Jeep. The seat mounts cantilever over about 6" from the stock jeep mounts and with 200-300 pounds in the seat and bouncing over rocks when crawling, didn't want to bend it. Maybe 1/4" steel would be OK but didn't want to have to make a 2nd set if it bent.

But why solid pate? Why not at least hollow it out.

Not to mention that box, c, or angle is more resistant to bending.

You are more then welcome to prototype/engineer/build/install a set of Honda Si seats in a XJ and have them still be adjustable and slide and be stable, strong, crashworthy, and not bend or come unsecured. I could have 'sculpted' out the middle 6-8" square and 'lightened' it a bit. Next time. The 2nd time around is always easier.

I apologize if I failed to be impressed that you successfully installed a seat from one vehicle into another. I am truly amazed at your great skill and experience. I will not second guess your obviously superior intelligence again, sir.

 

[CobraMarty]

OK?
