Hi, I have the IID just last week & would like to first try to calibrate my suspension before i order any height sensors.
Is there any how to guides? Also what measurements do I use, I have 22s 275/40/22 fitted? 2004 RR 4.4 V8 Autobiography

Hi Mate check out the wiki or go on Gap web site?

Thanks, good idea. I’ll look on gap as I checked wiki & couldn’t see anything to do with suspension calibration. 2004 RR 4.4 V8 Autobiography

Tyre/wheel size is irrelevant, you measure from the centre of the wheel to the top of the wheel arch so tyre/wheel size has no bearing..  Pete

Hi Paul, it`s down the bottom of the Wiki: DOWNLOAD & REPAIR VIDEO LINKS.

Ok well I’ve had a little go but my brain couldn’t understand the gap instructions 😬

So what I did was just measure 500mm from Center of the wheel to the arch lip & adjusted the heights so all 4 were the same. It’s all pretty level now as before my drivers side front was down about 30mm from passenger side front & I think that was causing the articulation validity fault. Seems to be ok at the min but I will look at it properly again.

Before I did they were as follows.
O/S/F 490mm
N/S/F 520mm
O/S/R 500mm
N/S/R 510mm 2004 RR 4.4 V8 Autobiography
