Re: Seat Bottom Mod For More Thigh Support

Sat Jun 09, 2012 1:30 pm

15 minute trip to the hardware store and 8 minutes to install (yup - no need to remove the seat). I went with two 3/8 nylon spacers for a total 3/4" lift. Sooo much more comfortable. Feel stupid for driving the car for a year and not even thinking this could be so easily fixed.

The nylon spacers are a great idea Ticktock! I remounted mine today with three of the nylon spacers (each side) and 45mm bolts for a total of 1 1/8" lift. I like the way the nylon spacers spread the loads out in a wider area than the smaller metal washers I used at first. For me, this lift feels perfect:

Here are the nylon spacers that TickTock and I used. I got mine at Lowes in the specialty hardware bins:

I did notice that when I used 3 spacers, it was difficult to get the bolts started into the seat pan. The spacers kept the bolts from aligning perpendicular to the seat pan. Pushing sideways on the bolt head a little forced it into alignment so I could screw it in and once the bolt got started, everything went in fine. With just 2 spacers there was no problem with alignment at all.

Wow! What a difference 3/4" makes. (Careful, guys)

While I don't consider myself mechanically expert nor mecanically challenged, it required quite a bit more than 8 minutes for me to get the job done. These old bones do not take kindly to working in sort of tight spaces while on hands and knees.

That seat never did feel quite right - big improvement. Thanks soareyes.

I finally got around to making this mod. It's great having some thigh support again. Thanks for the post & the great pictures soareyes!

Now I just need to figure out how to fix the headrests.

Yes, and I ended up using 40mm bolts with three spacers, which I think is the maximum anyone would want.
I'm glad this mod is working for everyone who has tried it. My next project is adding extra lumbar support!

It took me much longer than 8 minutes, too. More like 30-45 minutes.

I got lucky with lining up the bolt right on 1 side quickly, but the other side (the side near the door) took me forever to get it lined up right for some reason to get the bolt screwed in. After a while, I got tired and had my college-age son try to screw it in for me, but he wasn't successful either after about 10-15 minutes. So I tried again and finally got lucky.

I didn't have the seat removed, so it was awkward in the first place trying to maneuver around tight spaces while on hands and knees. I only did it with 2 spacers. I can't imagine how much tougher it'd be with 3 spacers and a 40mm bolt if you don't have your seat removed. In retrospect, it might have been easier to just remove the darn seat in the first place so you don't have to be on your hands and knees.

Same here. I think what finally worked for me was to move the seat cushion sideways a little bit. I forget if I pushed inward or pulled outward, but that finally lined things up.

I had my wife sit in the passenger seat and push/pull on the cushion until the holes lined up enough to get the bolt started using three spacers. I was considering elongating the hole a little with a round file, but if you are going to do that, it would probably be easier just to take the seat out.

For anyone taking the seat out, put the headrest down or take it off entirely, and tilt the steering wheel all the way up to make more room. I would also put a towel over the center console to protect it from being scratched by the metal seat runners. The seat isn't very heavy, just awkward to maneuver through the door opening.

Anyone know what quality the original bolts are?.. lots of stress on those bolts in an accident.
