A step-by-step pedal slider baseplate setup for sim racing. Learn how to adjust pedal slider position, set brake pedal distance, and dial in sim pedal ergonomics.

Quick answer

Mount the Pedal Slider Baseplate to your rig or seat slider, set the pedal plate roughly 15-20 cm from your seat front, then fine-tune the slider in small increments until your brake pedal reaches near-full travel with a slight knee bend. Lock the slider, sit in the rig, and test before tightening every bolt. If your pedals still creep or flex, check that the baseplate is bolted flat and the slider hardware is fully seated.

What the baseplate changes about pedal position

A pedal slider baseplate does two jobs: it gives your pedals a rigid, flat mounting surface, and it lets you move the whole pedal set fore and aft without unbolting each pedal from the rig. That matters because sim racing pedal position is not a set-and-forget measurement. Brake pedal distance setup changes when you switch from a loadcell to a softer pedal, change seat angle, or share the rig with someone else. The baseplate makes those changes repeatable.

The baseplate is also thick enough to double as a heel rest when you do not use a seat slider, so it can serve as a stable platform even in a fixed-cockpit build. Treat it as the foundation layer: get it flat and secure first, then adjust the slider, then adjust individual pedals.

Before you start: check the mounting surface

Set the rig on a level floor and confirm the pedal deck area is flat and free of burrs or leftover hardware. A baseplate bolted to a twisted or uneven surface will rock no matter how tight the bolts are, and that rocking shows up as inconsistent brake feel. If your rig uses adjustable feet, level the frame first so the pedal deck sits true.

Have the baseplate, the seat slider (if used), the pedal set, and the correct bolts on hand. Decide whether you are mounting to a seat slider for quick adjustment or directly to the rig as a fixed platform with heel-rest duty. That choice determines the bolt order below.

Pedal slider baseplate setup in 6 steps

1. Level the rig: Set the cockpit on a flat surface and adjust the feet until the pedal deck area is level front-to-back and side-to-side. Check with a spirit level on the frame rail, not the seat. Mistake to avoid: skipping this because the floor looks flat. A tilted frame makes every later slider position feel wrong.
2. Mount the baseplate flat: Bolt the baseplate to the rig or seat slider using all mounting points. Tighten in a cross pattern so the plate pulls down evenly rather than bowing at one corner. Checkpoint: press hard on each corner. Any click or lift means a bolt is loose or the surface is not flat.
3. Set a starting pedal distance: Slide the pedal set so the brake pedal face sits roughly 15-20 cm from the front edge of your seat cushion. This is a starting point, not a final number. Mistake to avoid: locking the slider before you have sat in the rig. Measure, then verify with your body.
4. Sit in and test brake travel: With the slider loose enough to move by hand, sit in your normal driving posture and press the brake to near-full travel. You want a slight bend in the knee at full pressure, not a locked-straight leg. Checkpoint: if your hip lifts off the seat back under braking, the pedals are too far away.
5. Fine-tune in small increments: Move the slider in 5-10 mm steps, re-sit, and re-test. Adjust for the brake first, then check that the throttle and clutch still fall under your foot naturally. Mistake to avoid: chasing a big move. Large slider jumps overshoot the comfortable zone and make it hard to feel the difference.
6. Lock down and re-check: Tighten the slider hardware fully, then re-check every baseplate bolt. Do a few hard brake presses and confirm nothing shifts or creaks. Next step: note the slider position so you can return to it after cleaning or a rig change.

Parts that support this setup

Pedal Slider Baseplate: The baseplate ensures secure pedal mounting on the Sim-Lab seat slider for easy pedal position adjustments. It can also be used without the seat slider as a heel rest and a stable mounting platform for pedals. You can run it as a slider-mounted adjustment plate or as a fixed heel rest, so the same part covers both a shared rig and a solo fixed build.
Pedal Slider Baseplate: Upgraded to 12 mm thickness from the previous 10 mm, it offers greater stability and supports a wide range of pedal sets and rig setups. It is compatible with P1X, P1X Ultimate, P1X Pro, GT1 Pro, classic GT1, and more. The thicker plate resists flex under hard braking, and the compatibility list means you can check your cockpit before ordering rather than guessing.
Adjustable Sim Feet: Sim Feet are adjustable feet for sim racing cockpits, allowing for increased stability and better ergonomics. The adjustable feet let you customize the height of the racing rig to your specific needs. They are sold in a set of four and are included with the P1X Pro cockpit. Leveling the rig with adjustable feet is the first step in pedal position work; if the frame is not level, your slider adjustments will not hold their feel.
