Outer Limits 4x4 Board

been lookiing at the X-eng telescopic type springs for a while. curious if anyone has seen, heard or used anything about similar set-ups? do they actually perform on the tracks? seen a similar system on an aussie rig years ago but can't remember who or what the rig was - wasn't a rover though.

any thoughts?.....

Bush65 is about to do the same thing using the additional spring under airbags.

Sorry, I assume you're Def9090

correct slunnie.

mate can't wait to see Bush65's build up!!

but i am thinking (yes changes daily) of going normal spring to spring no airbags (somewhat cheaper) and then run polyairs or similar in the main spring.

The only negatives I've heard about the X-Springs is a tendency to lift the back end when going down hills.

On the whole though, the competitors using them in the UK seem to be very happy with them.

don't want anymore of that in my 90!!


does anyone run them in the front too dave?? i suppose you'd get the opposite reaction too - lifting the front going up steep climbs? probably not anyway of overcoming this either - apart from a limiting strap, which would be a pain in the ass

thanks for your input

hey dave do you know this fella?

bit far from you but thought you may have crossed paths in the comp scene at some stage? curious to know, as you have done OBC, if you thought he may have a good crack at a top 10 or something? certainly has spent some coin on goodies...

Don't think they'll fit on the front without moving shock absorbers and I don't think they'd be of any benefit unless you altered the front end linkages. Not seen anyone using them on the front.

Only come across him on forums.

Looks to have the right combo of decent suspension and decent engine so could do well, depends how he approaches it. One thing in his favour is his vehicle being sat at Mike's place months before the event rather than having to try and finish the motor off during the show and shine like I did There's not much Mike doesn't know about the OBC and I'm sure he'll have some good advice for him.

Position in the OBC is all about pushing the vehicle as hard as you dare without breaking it. I was way too gentle with my vehicle this time out and I was kind of disappointed that, with all the pressure of finishing gone, I got my only top 10 stage position on the final stage so the vehicle had potential.. just me that didn't push hard enough ! My motor finished the OBC in better condition than it started it. Gary, in the Rangie, had less power than me but the same suspension system as the Swiss guy. Gary pushed way too hard and trashed his motor with a couple of days.

The main concern, assuming he gets the reliability balance right and doesn't screw up the navigation too badly, is the front winch arrangement which looks over complicated to me.

It's be great to see a Defender finish in the top 10 but top 20 is probably more realistic for a first OBC. Who knows though, maybe the new format and reduced numbers will help.

I would have thought that this setup would work very similarly to dual rate coilovers.
