well if they don't they are pretty much proving to me they are lieing through there teeth and that as soon IF i did do something like that and they said no i would return the seats get my dosh back and take the old 1 dollar pair i got of ebay to a upostlerer and get them looking like a set of really sporty seats...

That wasnt a set of seats, front and rear, for $1 buy it now by any chance was it?

$800 for a plate id say is a farce rumour ... would be no where near that at all....

Engineering prices will vary and can be greatly depending on the amount of work to be performed if the engineer is also performing the fabrication work, examining the installation and prepping the paperwork.....to have my whole car done over - s**t load of things requiring ADR paper work and i havent tocuhed my engine...was just under $800 and has taken me a few months to get everything organised....so for just seating and seat mounts to be inspected and mounting plates to be fabricated I would expect this to be under $500 all up...

Good to see your doing the right thing...proper process believe me bites a*** and costs decent ppl like you and myself who do the right thing thousands more than these bodgy dyi jobs like spring hackers trying to save a few dollars do who are the reasons why we have all this legal litagation etc....

The plate I believe just needs to be solid plate and round 3mm thick and secured with high tensile bolts and nyloc nuts - you need to confirm this with a local vehicle engineer....if you want dude I can refer you onto my engineer as he resides in queanbeyan...not too big a drive for you....hes approved my aftermarket seating which has had quite abit more involved...or at least discuss it with him over the phone to discuss your requirements for the plate and rough examination/certification costs.

The seats themselves (and most likely why they say they comply with the ADR's) is ADR 3 which relates to seating strength requirements....and ADR5 which relates to the manufacturing of additional seats....

There are also local codes you will need to comply with...NSW differs from WA and ACT.... in the ACT these seats need to comply with the VSB code....sections 5A or 5B...ADRs effected are ADR3 and 5....

Using the exisiting rails has saved you loads...the adaptor plates im sure will consisit of 75mmx75mm square plate - solid steel 3mm in thickness....this wouldnt cost much and any metal fabrication joint could make them for you....the nyloc nuts and high tensile bolts are available from most major hardware retailers such as bunnings and so on.

Bolts and nuts must meet the oem requirements used in the factory setups for mounting and anchorage points.

nah i won a pair of standard seats on ebay of an eb pov pack and it was in my local area

What u plan to do Froudey is fine but id still be at least verbally confirming this with either a vehivle engineer - or technial head of an inspection station... before you go waste money or fit something that could be unreliable or unsafe...your talking about your driver and passenger seats so i know id want to know these are going to be safe

Well i will be making a phoncall to bal dohnt the local engineer in dubbo and ask him about strenth etc etc and all that and dad and i will basically work every thing out and i will scan our plans and post it up in a couple of days what we are thinking are a stronger and thicker plate that autobanr sells and maybe i might weld some thin flat bar to help support the two main bars but any way i think it should strong and safe ( i wouldn't doing it dodgey as i love my wife and my life) so when everything is said and down these seats won't fail..
