Adjustable seat

[capt1black]

I am about 5-10 wifey is 5-2. She has to be able to drive car. I have both the breeze seat bracket and the FFR seat track. (Neither is installed yet) So my question is which gives more adjustability or anyone use them together? Thanks.

Do the seat track. You should be able to get about 5 inches of movement.

Funny, I have exactly the same challenge. I’ll check out the FFR adjustable seat. From what I understand the breeze seat has different holes but it’s not adjustable without wrenching on it....

The Breeze mounts give about three inches of adjustability, but requires you to remove the seat, make the adjustment, and reattach the seat. This doesn't cause me any concern as I'm the only one driving the car, but if you want to quickly adjust for different drivers, use the tracks. I wouldn't try to use them together. The track will raise the seat about 1.5" off the floor. The Breeze mount lifts the front of the seat about 2".

I have the FFR seat adjuster on my driver's seat. I made my own spacers that go under the tracks to raise the front of the seat an extra inch. A set of spacers were also made to go under the passenger seat so that matches the driver seat height and angle when the drivers seat is in the full rearward position. Here are a couple of pictures to give you an idea of how much travel there is. Compare the seat back location to the rear of the door. Sorry for the poor quality. The top is on and it is hard to get a good angle.

Unless she will be driving the car a fair amount of time, have a nice seat back cushion made up with her name on it. Saw a very nice example of this at the FFR open house four years ago. I am thinking it was a Pennsylvania builder's wife that did that.

I put Jeg's sliders on both DS and PS for two reasons. Adjustability of course, and also to make it easy to get in behind the seats for cleaning and retrieving stuff that ends up down there. They have the locking notches on each slider and are very solid. No slop or play at all.

I'm 5' 8", and mostly drive with the seat all the way rearward, but on long drives or in a lot of traffic I move the seat forward a notch or two to make that long clutch pedal travel a tad easier for me. The sliders added roughly 3/4" in height, which is perfect for my height.

Thanks for the tip, boat737. Just ordered a set from Jegs. I am thinking that I will only install on the DS....

boat737, which seats do you have? Does it matter? I have the Vintage low back racing seats ( waiting on my POL for the mounting hardware) and would love to install an adjustable seat on the driver side ( I am 6'3" and my wife is 5'5").

I also have the FFR low back seats. The mounting is a bit of an engineering puzzle. It's a simple process, but not necessarily an easy one. Basically, just drilling through the metal seat frame where you bolt to the slider (or through the floor if seat is mounted direct to the floor.). Getting everything to line up between the sliders, chassis tubes, seat frame tubes, seat back next to the body, and seat next to the trans tunnel and door frame area involves a lot of trial and error. I put the inboard slider right over the 4 inch frame tube. I also put the seats straight and parallel with the 4" frame tubes (some people angle the seat a little bit to more parallel the trans tunnel. I didn't need to do that.).

I did weld on some washers to add some strength where the holes were drilled in the seat frame. Hard to see in the pic's, but here they are anyway. I also added some aluminum material on the top side to help keep the seat cushion foam from drooping between the seat frame tubes (over time), and one on the bottom to hold the seat heater modules.

Thanks 737! I appreciate the pictures too. My vintage lowbacks are different in construction than yours ( Kirkey race seats) but the pictures really help get my mind around it.

Note of caution if using the FFR supplied sliders. I mounted the seat before the body was on and followed the mounting instructions exactly. Once the body was installed the seat was too far out and interfered with the door. Recommend installing the slider to the car as instructed but wait until the body is on to place the seat on the slider and determine where to drill through the seat frame. I ended up drilling new holes to mount the seat to the slider.

Definitely follow Norm's advice and wait until you can locate the seats with the body in place. I can't tell you how many times I have gotten cars in that the builder installed the seats with the body off and later found that they were either contacting the rear cowl where it curves around or crowding the door latch. Also, in regards to the sliders you need to install them so that they are parallel with the transmission tunnel NOT the frame rails.

Doing this will keep the seat equidistant from the tunnel as it is moved fore and aft. If you make the sliders parallel to the frame rails as the seat goes forward the front corner will come into contact with the tunnel and limit it's movement.

Good luck!

In addition to Jeff’s recommendation to angle the sliders I have angled the seats. I don’t know if this is a recommended by the experts but, after a few long drives my wife complained of back pain from the way I had the passenger seat mounted. I moved the seat by twisting it so her legs could go straight into the foot well with her back square against the seat back. She has to turn her head slightly to look straight ahead but, that is easier than twisting your lower body. She found it much more comfortable so I did the same to the drivers seat and found the same thing.

Not to dispute the expertise of Jeff and Norm, but I did put the sliders parallel to the 4" frame members, and the seat does slide fore and aft to its limits without contacting the body, the door, the rear wall, or the trans tunnel. It took many hours (or days) of measuring, adjusting, mocking up, and trial and error, but it is possible. The seats and sliders are straight and parallel with the 4" frame tubes, and within a 1/4 or 1/3 of an inch clearance everywhere, but all clear and good. Maybe I'm just lucky.

Sorry to bring this older thread to the top again guys, but having just ordered a Roadster kit, I’m curious. I have the leather low back seats they supply, so does the kit come with sliders or is that something extra you have to order? It’s the basic kit, not the complete kit. I can easily order a set from Jegs or run down to Summit and pick up a set. I got plenty of time since the kit doesn’t come until November.

Cheers

They were extra when I got my kit last year. You only need 1 since you will probably never move the passenger seat.

Thanks, Chris!

Dave,

Keep in mind that if you suffer from OCD like many of us, the sliders will raise the height of the seat a bit. If you want them to be the same, you'll need another set or some spacers to get the passenger seat to the same height.

You OCD guys need to get your meds refilled. :rolleyes:;)

[boat737]

I have sliders on both the DS and PS. The DS I use for driving adjustments (usually on longer drives), and both for cleaning and getting behind the seat to retrieve whatever manages to work it's way back there. Amazing how cramped it is back there.

[A12pilot]

Ok, think I got it; buy one slider, lose sleep over unbalanced car, buy other slider, sleep easy. :p

Check!

I used to be OCD but now I am CDO. That is the correct alphabetical order. Much better!;)
