I really like your system and construction, very solid.
I recently did a repair on a friends work PC and when his son drove rF2 with my average PC + wheel setup ( even with Broken FF ) he was hooked and on the spot arranged for a high-performance build early next year.
As he is involved with long distance trucks I gave him a go of Euro Truck II, now he was gob smacked. lol
I was not prepared for what he said next.
He eventually wants a Simulator for Trucks lopl
He is going to CAD and build with boxed alloyand Mig
( his dad owns a precision workshop )
He wants, get this ......
CSW with his words " a much larger wheel "
Proper grearshift, in his words not a toy
Large heavy load cell pedals inverted with throttle bottom
Large truck type rubber pedal plates
Make a good project lol
