A workmate got a set from CRS for his HJ Holden and when he went to rego (ACT) they told him to take them out and put the stock ones back in. They are supposed to be engineered for all states but ACT don't recognise Hadfield as a qualified engineer, this was two or three years ago so things may have changed. Best to consult your local rego before forking out your hard earned cash.
You know, somebody actually complimented me on my driving today. They left a little note on the windscreen. It said, 'Parking Fine.'So that was nice.
