Outer Limits 4x4 Board

My dad just bought a 95 classic rover with air suspension, I havnt really seen it in action yet but from the little reading that ive done it seems that the higher it is pumped the less wheel travel you get. If this is the case then Id imagine that when on a rough track the automatic suspension lifting is not nessasarily desirable. would fitting some sort of spacer under the bags increase the articulation?

p.s has anyone ever had traction control engange when doing tight turns?
Whats the consensus on these a off road vehicle, the amount of electrics on it are mind boggleing, thinking water?

Hey Mup.

Dunno about your ETC whilst cornering, it could be ABS kicking in (sensitive) or maybe just ETC sensing a wild difference in the wheel speed (inside less than outside)
As for electronics on these rigs - they're generally okay, it's usually the mechanical bits hanging off them that fail first. My P38s does not shut up - telling me this and that has failed, but to date they've all been ridiculously easy to fix - and at least it tells me somethings not working.

Yay, pumping the height way up does reduce the available 'down' travel (droop) of the axle as the airspring can't 'stretch' any further.
This will also affect the ride comfort. The airsprings need a higher pressure to acheive the higher height - same as having stiffer coil springs.

Fitting spacers will allow the vehicle to sit higher overall, while keeping the airsprings in the middle of their desired travel range. They work best within about 1/3 of their overall travel range. If you fit spacers, lengthen the height sensor rods or relocate them with a bracket - either option the same size as the spacers. 2 inch will be a sensible mod.

Spacers could help increase overall articulation if you are careful. By fitting longer shockies and paying close attention to the bump stops, you may be able to gain an inch or 2. You don't want the top of the bottom piston to smash into the top cap though nor do you want the airspring to rip off it's mounts (easy to reinstate if ever happens though)

Alternatively, try comparing P38a airspring sizes against the Classic. You may be able to move your rears to the front (incl pistons) and buying some P38a rears. Then get your friendly mechanic to rejig the EAS ECU height setting for std and offroad settings.

I've already done all of this bar the spacer thing, which ultimately may be the way to go. As it is now my std is 15mm higher - combined with bigger tyres I have just over 2" extra under chassis. My offroad setting is now another 2" higher again (all up 4" more than a bog stocker at normal height) The offroad was even higher before - a full 85mm over standard, standard height - I deliberately dropped back to give 50mm over the 15mm higher std height to give a bit more droop. Std height is now good enough for tooling around in the bush, reverting to offroad only when really needed - logs, creeks, approach and departure.

I think SNAKE Racing make 2" spacers for SLS Discos, but it could be easier than that. Attached is pic of 1" spacer I made while mucking around - cut out is the shape of retaining lug for bottom piston.
The other pic is front airspring & piston (both from rear) at earlier reprogrammed max height - only about 1.5" of remaining travel left there!

thanks mate now I just have to convice him of what he really wants to do lol

No worries - you could get the old fella to convert to coils too.

It was Rovertym that make the SLS spacers, not Snake

Dunno where my other pictures went...
