    Hellooooo, does anyone know a way to adjust the brake pedal height or throttle pedal? Or maybe even some plates that go over the face of the pedal to help.

    My issue is I really like to use my left foot to brake at track days, but with the mustang the brake pedal is a lot higher compared to the throttle pedal. Which makes my left leg cramped up and my right leg a perfect bend.

    Any suggestions?

    I've never done this, but seems plausible: Could you remove the gas pedal assembly from the firewall and make a bracket/spacer to move it where you want it? You may also have to make a stop so you don't break it at WOT as well.

    That seems like a way that it could be done, what do you think of adding some sort of material to the pedal surface to extend it that way? I might not have to make a stop then too

    My charger had power adjustable pedals... Seems like this car
    needs that option...

    In any case, this is the best you're gonna get without mods:
    Items you will need
    • Flashlight or portable shop light
    • Throw or rug
    • Ruler
    • White liquid correction fluid (like White Out)
    • Wrenches
    • Pliers

    Step 1
    Put the throw or rug on the front floor of the front seat. Set up the light on the passenger's side so it shines up under the dash.

    Step 2
    Stop the engine before you test the free play in the pedal. Pump the brake twice to remove any vacuum. Press down lightly on the pedal with two fingers. You'll feel it stop abruptly; that's the master cylinder stopping the free play.

    Step 3
    Measure the distance from the top of the brake pedal to the floor with a ruler. Take a second measurement after you depress the pedal. Find the difference between the two numbers and you've found the amount of freeplay in your pedal. About 1/8 inch is average. If your pedal feels mushy, the difference probably is greater.

    Step 4
    Look at the back of the brake pedal until you see the point where it attaches to a push rod, which is the brake booster adjustment rod. Make a small dot with the liquid correction fluid on the bottom of the rod. This gives you a point of reference in case the rod turns when you loosen the nut.

    Step 5
    Loosen the nut at the top of the rod. Rotate the rod. Use the dot to realign the rod back to its original reference point if it moves.

    Step 6
    Turn the rod. When you turn it to the left, it tightens for less free play. Turning to the right does the opposite. You may need to use pliers to turn the rod.

    Tighten the nut to secure the rod again. Test the pedal with finger pressure to ensure you don't have to adjust the pedal height even more. If it feels within range, test drive the car.

    Only concern here is if you are Drive by Wire, be careful not to disrupt the pedal sensor so there are No Throttle Body concerns.

    It's all one assembly on our cars.
