During todays session on the rolling road at Glenrothes, I have noticed a difference in the drag'lines' between WRX Imprezas and UK spec cars. This was a mystery to myself and to Jim of Star Performance as we both assumed that the drivelines were identical. The UK cars have a nice progressive run-out line as the speed decreases but my car and another MY93 WRX gave readings that dropped in a similair way to the UK ones, then had a shrp decrease in speed in the middle of the range. Does anyone know why this may be? Are there differences in the driveline? I think it may be the rear diffs being slightly tighter but i'm not sure. Thanks for reading my wafflings
