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 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.
Many online images show double bearings on each clutch ramp; mine was received with single bearings.

Current 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 preload damping encouraged experimenting with:
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.
