Well, i had to clean right button, since it had a burst of pepsi there (don't ask) So when my shiftercable collapsed, i disassembled whole thing (also sawn-off plastic under the steeringshaft so cover could be lifted without detaching the whole wheel again) and cleaned/greased it with molyspray.
Left button still works perfectly fine, no repairings whatsoever.
Shifter had it's bending wires (the ones, conected to resistors on the lever's bottom) replaced, due to wear (yeh, them geurz didn't want to engage, just like in real cars, lol)
Pedals are indestructable, compared with ACT-labs system.
Also, no resistors been flicking yet. (Which is very cool, cause it's been like... over 7 years of "Grind, cluck and stomp!")
