Got any more details on that such as a reference? As I note that WA also has adopted the NCOP ( http://www.transport.wa.gov.au/media...htVehicles.pdf ).

Not sure where the references are but when taking the car over for inspection they had to be removed before it was passed. Also on most boxes that coil overs come in they say for off road use etc.

Not illegal in Victoria

Section 13.2 VSB 14 lists that you can substitute suspension components without certification - provided amongst other things it is not raised or lowered by more than 1/3 of its initial suspension travel. No mention of coilovers as exclusions.

Cars with ESC may be different - as lowering or raising may affect the way the ECU responds to its set programming ? This is more to do with parameter alterations than hardware change - so it would apply to lowering / raising the vehicle regardless of coilovers or using lowering springs.

This doesnt stop the boys in BLUE questioning anything they want to question - just means you are obliged to prove what you have modified is within the rules legislated by your state.

Hi Guy's,

I have been going over the regulations, and from what I see we comply with all of the reg's under the vehicle standards rules. With the Ford we have retain all the of the Factory rod travel and just a little shorter in the rear by about 12mm from memory but fall way inside the 2/3rd's rule for travel. We have also extensively tested the car's performance with the stability system with no reduced effects on performance. Section 4.4 outlines compatible mountings which we have the same dimensions as factory but the Ford lower clevis bracket for BA-BF is 2.5mm thickness and our brackets are 5mm thickness to make sure we have super strong mountings.
From what I see we are all good but will keep going over as now I am interested to read this material.
Cheers

Brett - Isnt the factory unit on the front of the Au and B series and FG series a "coilover" unit anyways ? It is not a separate spring / shock.

The only difference with the shockworks stuff / pedders / tein etc is that they are "adjustable". In fact the Tein with the EDFC may be an issue as it has the potential to be "manually" adjusted whilst driving ?? Not sure on the technicality of that.

The rear units are a separate shock and spring - like the factory units as well - so there is no modification per se.....its more in line with the substitution rule. Now adding a complete coiolver kit to an XE falcon may be an issue as the body of the vehicle may need to be modified to suit.

This is an interesting area and probably comes down to interpretation of the regs. I'm sure there would be roadworthy testing centres out there in all states that would not pass on these sorts of mods out of pure confusion and caution. Then again - there would be plenty that would based on the substitution ruling.

I think a full coilover unit in a XE would be very difficult or dam near impossible. We are now making dampers for the XY Falcon and would not consider changing too much but they are adjustable at the front and an inverted monotube at the rear so you can adjust at the lower mount. We are looking also at a CNC to mount with bearing for the top. My only concern for WA id the base height adjustment so may introduce a fixed base adjustable damper.
