When designing the mating interface between your Toyota truck/SUV and the scheel-mann Vario F seats, Tolerance Stack is content playing the unobtrusive go-between.

When deciding on a seat upgrade, it's usually a defining moment right?• My back hurts, time for better seats?• I can't do long trips anymore because of my back.• Back surgery, no riding in the truck for me anymore.• These seats are ugly smell funny, and are ripped.

• These OEM seats are horrible.• I'm about to sell this truck the seats are so bad.

Now that's settled, its time to research seats right? Keep it simple because there is only ONE compamy even making an all-in solution for your Tacoma, FJ Cruiser, or 4Runner. That is where Tolerance Stack comes in and with the task of staying out of sight, playing nice with Toyota and scheel-mann, and just getting it right the first time.

Techstream refers to Toyota's factory diagnostic and reprogramming tool, allowing technicians to access vehicle data, troubleshoot issues, and reprogram ECUs, and is available in both full and "Lite" versions. This quick write-up assumes either you, your installer, or technician has access to Techstream.

When you are removing the OEM, computer calibrated passenger seat, with an upgraded aftermarket seat, you must get the seat's weight to the same as you are taking off. With the Tolerance Stack mounting system the solution is built-in. With addition of washers under a tensioned spring you can calibrate by adding washers to adjust the pressure of the spring.

If its determined that you need to use Techstream to accomplish the zero-point seat calibration, simply follow along with the written instructions found here: https://www.tolerance-stack.com/technical or follow along with this video:

We are starting to see it more and more- folks surprised by rusty rails (no, not rusty nail, that's Scotch and Drambuie). Unless you live in the Southwest desert you are likely going to see some rust on your seat rails. There are a few reasons for this: maybe you live near the coast, maybe you live in a rain prone area, maybe you've spilled a few drinks...

So what happens when you commit to your scheel-mann Vario investment to help mitigate your sore back issues on long drives, and you are knee-deep into the tear-down of your crappy OEM seats, and then you are confronted with rusty rails?

Well, its definitely not the end of the world. You could absolutely ignore it because only the seat feet will be seen at the end. You could simply spray the rust with some silicone oil to prevent any…

Scheel-mann Vario F seats have a design to their seat bottoms that allow them to be lifted up to gain access underneath. This was originally designed for the Defenders because the battery was under the seat. But for the Tacoma, FJ Cruiser and 4th Gen 4Runner owners you get to utilize it for storage. We've specifically designed the seat bracket in both the non-Klima and Klima compatibly seat pans to take advantage of this space and allow us to design a storage bin for both the passenger and passenger seats.

Yes, the scheel-mann Vario F seats are designed with the feature that the lower seat lifts and thus making anything under it accessible. This gave us here at Tolerance STACK the opportunity of actually designing in extra storage availability into our Tacoma, FJ Cruiser, and 4Runner seat mount designs.

In the non-Klima seat pans, which you can see from the…
