just done the r32 arb mod massive improvement in the roll on the body, also have removed the SAI as well feels like I might have been having a boos leak somewhere along the line :S Also have set the steering wheel central in relation to to the rack as there seems to be a sensor for the esp which I would assume would cause odd reactions by the esp?

What makes you think the steering wheel wasn't centred before you adjusted ?

Physically re-centering the steering wheel should ideally only be done after you've had the tracking and geometry done.

After geometry setup has been done, ESP Steering Angle Sensor Calibration then ideally needs to done.

The steering rack track rods were uneven one side pretty much had no thread and the other side had loads. So I set it that there was zero degrees toe in with even number of threads showing on the track rods as a base point. Then removed steering wheel and re centred cheers for the link Snow Muncher had found something similar yesterday when looking at calibrating

The steering angle sensor can throw things off under near full lock
