So who here has got an engineers certificate for their airbag lift?

[Pete38]

Including the HRA kit and the individual designs that have happened recently.

Have been looking at disconnects for the front sway bar and it brought back my thoughts about looking into a certificate.

Do we need a certificate for anything under 50mm?

From what I've seen, most are FAR over engineered!

[Pete38]

Well we have modified the suspension so I would have thought so. If it was a coil lift then the coils are bought rather than home made.

Not sure how to take this document below. I'm assuming suspension mount points likely means the swing arm mounts, axle mounts etc. And not the airbag mounts.... but not sure

It's a grey area... It doesn't mention spring spacers having to be made professionally. The way I read it is that 2" or less and you don't need a cert. if you modify radius arms or trailing arms, a-frame, etc then you need to speak to an engineer.

don't you have a big rectangular button with arrows on it negating the need for a nosey plod to pull out his tape measure?;)

Coilers cannot do this

Well truth be told I send mine to highway height whenever I see an RBT. But its not Mr Plod that I'm worried about, its insurance.

My bro lifted his GU Patrol 2", told his insurance company about it, they did not ask which company manufactured the lift.

As far as I'm aware, the onus would be on the insurance company to prove that the modification directly caused the accident/damage. Or at least prove it played a significant part. If the rangey over turned as a result of a swerve maneuver, it would be a messy insurance recovery process I'd imagine. Would you feel confident in passing the "Elk" test now, verses pre-lift?

[Keithy P38]

Gotta ask, what does ELK stand for? Emergency Lane K.... I'm guessing!

I definitely think mine would pass a lane change test. 2" has not changed the on-road dynamics enough to notice.

Yeh true. The centre of mass hasn't shifted much as a percentage. And with less roll from the gen 3's the mass doesn't shift as much sideways as the stock bags either to encourage the car to more likely roll.

And decent shocks that aren't to harsh to encourage lifting wheels or too soft as to not damp.

[davidsonsm]

Have to agree. The upgraded bushes, shocks and air bags (plus brake rotors) have to be an improvement over an averagely maintained 15 year version of the same car.

The ELK test is a Swedish swerve test - that caused the Merc A class lots of problems when it was first released. And led to Merc going back to the drawing board. No doubt in Canada, its a Moose test.

And "Roo" test in Oz perhaps!

[benji]

Or an emu test. At least kangaroos don't try and give you a hug through the windscreen.

Basic physics should dictate that if arb's 6inch gu kit passes the Australian Lane change test, a 2 inch p38 won't have a problem.

At standard hwy height with the gen3 bags it handles stupidly well, and very neutral too.

The Elk test is a lane-change manoeuvre to get around an imaginary Elk. More commonly known as the Moose Test, in Canada.

(Sorry for digging up old threads.. I was interested in airbag lifts) ;)

ps. It turns out I forgot to read page two where someone had already explained what this test was.

[Pete38]

I assume you've now seen the sticky topic then?
