    How many kg load cell? 60? 80? Just curious, as F1 have exceptionally hard brake pedals, DP, not so sure...probably closer to GT car brake stiffness and progression.

    It maxes out at about 40kg at the pedal face. The load cell itself has a higher rating but after factoring in the leverage the pedal creates it nets about 40kg at the center and about 35 if pushed near the top edge.

    I believe Daytona Prototypes have a brake booster, so they're more like a GT car in pedal feel.

    A bad quali means I can go forwards in the race. Premium

    For those who wish to emulate an F1 cars brake pedal feel I wonder how much G-forces under braking influences what the driver is physically doing?
    For example if the driver is pulling 3-5 G under brakes he weighs (70kg driver) 210-350kg. Take 50% of that and its 105-175kg per leg. Yes I know his race harness is taking a lot of that but the driver effectively is just supporting 1/2 his weight on the pedal to push 100-175 kg.
    Quite a different excercise to sitting in a chair at zero G and trying to muster 100KG or more.

    My point? Maybe a load that is greater than 1/2 your body weight is more than enough in a static situation? Dont know just thinking out loud.

    That's a great point, but I think that they don't keep 150Kg for more than 0.5 seconds, and most of the weight is countered by the seatbelt, so I still find 100Kg to be acceptable for static loads.

    100 kilo's is more than enough. Although the driver wears belts. They get a load of extra weight in the pedal by sort of stretching their leg and let G-force help out.

    The G's don't really do much to help with braking as I've read from some engineers as-well as Niels H. I think F1 brakes max-out at around 125 kg.

    Has any one tried the brake spring upgrade From GTeye, as postage from the US is high?
    Or is this available in the UK

    Amazing mod, this word describes it perfectly.
    I think they have multiple postage addresses, as I ordered mine from Brazil and it was shipped in Brazil, so you might want to have a look at it.
