Thank you all for your input..
I have looked at changing the POT's , Jaycar have a great number of them of varying values 1K, 5K, 10K etc which has stopped me from changing them as I cant find anywhere the value of the stock ones.
I found a set of T500 pedals on eBay which I was going to get until I surfed by the Fanatec website and checked out their collection. The CSL Elites (with the clutch and loadcell) made me think twice about the 2nds T500.
So it comes down to as it always does, how much $$ I can stop the missus from spending so I can spoil myself. When you see me real big in the rear view mirror, you'll know I've got me new ones
See you on the track
