Thread: Confused on measuring suspension height to check if compliant (suspesion/tyres)

Um - how exactly? What would it achieve? So we all don't drive our 4x4's for a week or a month? So 20% reduction in traffic while we still pay rego on them. Tradies not being able to make a living while achieving exactly **** all - that's really showing them who's boss...

I would have thought telling your local State member what you thought and why you won't be voting for them would be far more productive.

Can anybody shed light on my non ESC Hard Top.....

1. How do they check unladen heights
2. Full Bump
3. Is the link above the measurement they are working off....oh I had a quick look and it appears 130 HCPU has same suspension heights as a 110HT

No sure what the go is with after market suspension rods for discos and range rovers.

Do do you have to get a mod plate for the airbags Weeds, or is for your own peace of mind?

Don't quote me on this, but my understanding of 'full bump' is when the axle is resting on the bumpstops.

This so called new system is going to be the most unworkable in history:

1/. Just had a quick peek at the RVD1 for example the D2.
According to the RVD1 data, on the rear; centre hub to top of wheel arch is 475mm
RAVE has a spec listing for the D2 measurement; coil spring = 483mm -+15mm, or air spring = 473mm +-15mm

Already we have a discrepancy between the manufacturer data provided and what the govt regs supposedly state!

ie. if someone comes along being a total PITA to check your lifted D2 and they do the measurement and take it as 500mm does this mean your vehicle is lifted by 25mm?
If you go by LR's data, which allows up to 498mm(ie. 483+15mm allowable) as std for the coiler, you're only 2mm above std!!

2/. How do they measure centre of hub to 'top of wheel arch' if it's a ute fitted with a tray?

3/. what if you cut your arches(as can be common) and fit flare extensions(which I presume will still be legal to certain degrees) and the new arch extension is actually lower than the original pre cut std wheel arch height?

i'm pretty sure when you remove the coils completely and air-suspension......it requires a mod plate

Yes, I agree on bump stop but mines comes no-where near their measurement....

good point about trays, I hadn't thought of that......

didn't realise RAVE had measurements.

did they actually change any laws?

or are the just actually enforcing what was there already?

not that worries any of my vehicles thankfully.

personally i am glad to see someone trying to bring some sort of reason into the equation.

nope, no change yep, just enforcing the current laws........that's me reading between the lines. agree about making it equal especially although hard to find the exacts around ESC fitted cars
