Thread: RRS Ground Clearance

Garry,
At the LRExpo this year Bruce Davis had an electronic box that could be used to change the 'standard' heights for the RRS, D3 & D4.

Check out this thread which relates to a guy on the forum who seems to have developed a controller that allows different heights to be set and effectively "off road" height to be maintained above the 50kph.

i believe it is being distributed via Bruce Davis.

Thanks guys but that is not the issue. That system allows you to select various height settings within the design parameters of the vehicle.

The issue I have is that a RRS on its offroad setting is a full 83mm lower than a D3/D4 and they are supposedly the same vehicle underneath. So logically a RRS should be able to get to 310mm when offroad.

With only 227mm, a RRS will not be able to go many more places than my old Freelander will go if ground clearance is a limiting factor.

Cheers

As far as I know the offroad height of the RRS is only slightly less than the D3/4 due to slightly smaller tyres. Having both an RRS and D3 I can vouch for that.

The RRS has different suspension geometry which probably accounts for the difference in height. The ramp over angle is about the same as the RRS has a shorter wheelbase.
If you wish to raise the height in all settings you could install shorter suspension rods but that would compromise the on road handling.

Maybe 227 should be 272, which accounts for the tyre size difference.

With a Llams unit, the vehicle could be jacked-up front and rear at calibration time when at off-road height to provide a higher Llams off-road setting. How high would you like off-road height? Normal height would not be affected.

Yes but the maximum you can ever go is 227mm (as that is the max built in available height) not anywhere near the Disco 310 mm. No amount of tricking it will make it go higher as it is a physical limitation. To me 227mm is just too low for any serious offroading.

Will D3 airbags etc give better ground clearance as I though the suspension geometry was the same as a D3.
