ProtoSimTech PT2 pedal set


ProtoSimTech pedals were positively reviewed by Barry Rowland.
  • pedal adjustments video
  • mechanical adjustments video
    batch variations Barry's is among few other PT2s seen with pedal pivot bearings instead of bushings.
    • Barry's PT2 review version had a load cell amplifier gain potentiometer that was missing on mine.
      PT2 batch 3 and earlier used a 12-bit DSD controller.
    • My RaceDepartment PT2 comments
    • For batch PT2 4 and later, load cell gain is adjusted by Bodner LC-USB software
    • My throttle pedal bump stop has jam nuts above and below hex crossmember,
      while Barry's and the PT2 improvements video demonstrated hex socket jam screws...
    • By batch 8, bump stop adjustment had reverted to double jam nuts.
    • Chris built 9 batches;  here are his YouTube videos
    • Many online images show double bearings on each clutch ramp;  mine was received with single bearings.
    • bolted (not tabs in slots) load cell:
    loose load cell mount Purchased used 5 Oct 2021;  received 14 Oct with load cell mount issue.

    Clunk at end of preload
    Rigid spacer inside preload spring wants rubber washers to damp contact.
    Brake pedal threaded rod 5.8mm (M6) o.d.; elastomer tube 7.8mm (5/16) o.d.
    Brake elastomer stack disassembly for:
    Heusinkveld Elastomer Kit (manual) Dimensionally compatible with PT2 and advertised as providing:
    • much more progressive brake feel
    • firmer bump and rebound
    • no degradation over 1 million cycles
    • 19mm hard elastomer
    • 19, 28, 37mm soft elastomers

    Spacers are wanted to match PT2 elastomer tube length:
    • top center:  black nylon washers included in Heusinkveld kit for reducing travel;
      redundant to PT2's preload adjustment.
    • PT2 black elastomers:  left of hard Heusinkveld elastomer and improvised spacers

    Elastomer restacked:  Heusinkveld hard + one PT2 black


    Rubber washers around preload spring reduced "clunk" and increased feel credibility.
