Neil, sorry mate but I have got to disagree with you.
Most adjustable coil over kits are good for road and track because of the versatility of the adjustments.
In your case with your KW3 set up, all that is required is a bit of adjustment and fine tuning on the compression and rebound.
Also remember that you have dropped considerably and you have not had your geometry set up properly, so your toe, castor and camber will be all over the place which is not conducive with good ride quality or good handling characteristics.
