every state is different, if your determined to do it legally best check with the relevant authorities. I know over here in WA, they have recently changed the rules to allow you to go lower as alot of newer car's were below it, there is still other rules regarding headlight height etc that then take affect.

alot of laws relate back to adr (australian design rules) and that specifies basically 100mm forward of front most axle, and rearwards of furthest rear axle.. but inbetween, you can be lower based apon a forumula that incorporates the length of the vehicle, the wheel base and then a percentage... which then give you the lowest legal hieght for the centre section of the car

alot of people even police will tell you its 100mm in most states, but infact adr over rules alot of these in alot of cases, i know victoria have vicroads guide lines which are based on adr, and have basic specifications with references to adr's for detailed specifications

If you want to stay hassle free, I'd stay about the 100mm all around.

My stock series 2, except for some Tein low down style master coilovers, sits at 350mm front and rear. The exhuast next to the diff is getting pretty close to the 100mm point.

I have dropped my S1 a bit further on the Bilsteins and its now 340 front 350 rear which is about as low as i want to go. As someone pointed out lower than that (apart from bottoming out on driveways) you start putting excessive angles on your universals (CV joints).

At the above ride heights its comfortably above the 100mm min. In NZ you have to have a minimum of 100mm below any substantial part of the car (diff, sump, chassis rails) but not including appendages such as exhaust or side skirts.

For QLD drivers

that should give you all the info you need.

I would assume all states would have a similar information package.

Don't forget that, regardless of how high your car is centre of wheel to guard, things like exhausts may still be lower than the 100mm limit. I've heard that sometimes the car is measured with a full load, i.e. if you're driving around with passengers and/or a load, the car is measured to make sure it STILL sits above the legal height. *Disclaimer: that might be speculation, I'm not sure how true it is...

Best to check with your state's authorities, although it's about bloody time they nationalise the standards so we don't have to worry as much if/when we take our cars interstate.

Another thing is that ADR's should out-rule any local state rules, but it doesn't always happen that way.

      Jacks that fit under GTR lips that can reach the subframe?

      By TurboTapin · Posted

      For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      Looking for someone with a R34 front bar

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
