GQ Y60 Cost vs Best way to achieve 3"+ of suspension lift

[Peter Connan]

VIN number starting with ADNC350000?
If so it's the same as mine.
I mean they came that way from the factory. In the manual it is described as an option.

Hi,

yes, starts with ADNC350000

Thanks

Question regarding the rear axle and suspension when lifting a QG/Y60:

In the front, the axle moves towards the rear of the car as lift increases, so drop boxes, caster correction bushes etc are used to get the axle back in the right place.
What happens to the rear when lifted? Does it move towards the front of the car? Struggling to understand the 5 link compared to the 3 link front.
Also, at what point/lift are adjustable or longer panhard bars needed?

Thanks,

[Peter Connan]

Yes it does. And the axle's angle also changes.

Most people seem to feel that after 3" you need adjustable panhards and adjustable upper control arms (to remove driveline vibration caused by the angle change).

However I feel it is not ideal to adjust the panhards such that the axles are centered under the car at ride height unless the bump stops have been extended.

My reasoning is that an extended spring can handle mis-alignment but a compressed spring struggles with that, and if the bump stops are standard height the axle will return to the middle of the car at full bump, but go past the middle of the car at full bump if longer panhards are fitted.

That makes a lot of sense what you mention with the panhard and springs, I never thought of it like that, thanks

Merry Christmas all!

Quick question, incase someone can help,

I'm very interested to see what height suspension lift my GQ has (have the shock part numbers, but not the springs, and have no way of telling what they are), a bit off topic from the thread, but anyway...

Can anyone take some sort of measurement, front the center of their wheel hub, to the fender flair on their GQ (also what lift or no lift you are running) so that I can compare mine? front and back would be appreciated!

Thanks!

(can't remember if i've asked this already...)

Can you download this file Andreas:

I can't.

The information I have is that the front should be 565mm. It is safer/easier/more accurate to measure the spring installed length, which should be 302mm.

Unfortunately I don't have this information for the rear.

Measure the distance between bump stops

Sorry, just went to look at the pictures of your car again.
Looking at it's stance, you alreary have 2-3" of lift. Probably closer to 3 than to 2. So unless there is something wrong with the way the car rides, I would just keep the springs and shocjs as they are.

If the rear springs are constant-rate, then the Terrain Tamer progressive rear coils will improve the ride.

So, as Tinus and Peter mentioned,
I measured the bump stop lengths front and rear (not the stops themselves, but where they contact).
So my car has a 2"/50mm EFS lift kit in, or an extremely droopy and sagged 3" (which I doubt).

The OEM front bump stop distance is 65mm, mine is in-between 110-115mm (just a lightishfront Bar in the front)
The OEM rear bump stop distance is 100mm, mine is in-between 150-155mm

Just fyi
