For anyone in Sydney who's lifted over 2".

I am sorry for being rude. Some people should not quit smoking, no wonder they all cheered at work when I said I was having today off. Thanks for the wake up call.

There are a limited number of engineers willing to approve a lift on a vehicle with stability control, a 3.5" kit and 35" tyres is about a 5" lift. It is different to an older vehicle that does not even have airbags.
I would not be looking for someone with Jeep experience but someone still willing to lift a vehicle with stability control.

If your two existing engineers will do it I think that it would be easier to stick with them rather than use a new engineer.
If you talk to a new engineer then have everything in writing in front of you for the first call eg stock track, stock rim offset, proposed rim offset, stock tyre height, proposed tyre height etc so that they know that you have it covered or they will say "sorry we specialise in funeral cars" even if they have done the same thing a month earlier.

...It does make you wonder what the whole point of certifying modifications is when there are inconsistencies amongst engineers like the one you have highlighted

Also interested if you have an answer to rayzors question on running 315/75 on your rims rubi4door?

You'd think they'd be glad to see some easier repeat jobs come in, maybe they just have too much work on and don't need the customers ..........................

No wuckas, I was a fun guy to be around when I binned the durries too..... If you'd like to PM me the details of the bloke you used, I'd be happy to have a chat to him.

Just dragging this back up in light of the new sticky for tyres and lifts and because I've seen a couple of JK's getting around on 35's, and even 37's, with big lift kits.

So who's legal and who's risking insurance cover and liability? Not trying to be a clown, just making sure everyone's put some thought into this.

I am in the process of fitting a 4" spring lift (Currie 'Rock Jock' short arm kit) with JKS panhards and disconnects myself. My engineer stated no more than 150mm overall lift, via tyres and suspension. Tyre size not to exceed 33's without brake testing. Apprantly the brake testing is destructive......

I am fitting SSBC calipers on stock rotors so I can try for 35's once I've worn out the 33's.

I was wondering if others have gone to this trouble, or know that they have to in order to make sure they're legal?

when did JKS start making a panhards for RHD? i messaged them about a month ago, and they told me that they don't do one, unless your taking about JKS control arms and not panhards?

Have been curious about the brake requirements for larger tyres myself. What year is yours, or more precisely do you have the smaller or larger front discs?

Also, tyre size not to exceed 33" without brake testing, this is only one inch bigger than the largest stock optional? I thought you were allowed to go 50mm? Although having said that I have never seen 34" tyres, so I guess that answers my own question...
