What is the best comprimise in setting up suspension travel to crawl in the rocks.
Should you run really flexy suspension with equal up and down travel. I found this type of setup crawled really well when I had small tyres (31s) and didnt need heaps of lift to clear the tyres (would RTI 1300 on a 20deg).
Went to bigger tyres (36s) and just lifted everything up (with spring spaces under the coils 3in), lowered the shocks and put in bigger bumpstops so I had exactly the same travel with the 36s. All my rig wanted to do was flop on its side and because the sus was 3in higher and to soft. My front arms were angled more and the rear had heaps more anti squat (both of which is bad). (would still RTI 1300)
Then I ran the same shocks and bumpstops with shorter stiffer springs (about 1in lift) so my rig sat lower (more stable) my sus geometry was closer to origional so it worked better throttling up climbs. I left the springs unretained so I had heaps of droop (springs coming unseated) and not as much compression travel. This worked better but I felt it was still too unstable. (still RTI 1300)
So I now have retained the springes top and bottom so I have about equal up and down travel and the sus is a lot less flexable but at least it dosent want to flop on its side all the time and the loss in articulation had made it worse in the reallw flexly stuff (makes it want to fall over on three wheels) (now it RTI 1000 on a 20deg) So far this is the best setup I have found.
So whats everyone run?? Heaps of droop and not much compression with the rig sitting lower. Or about equal travel up and down with the rig lifted higher??
What about buggy leaves, revolvers, or wacky shackles any one run em to get more droop or does it cause the rig to be too unstable??
How about the dual rate coilover rigs with the stiff upwards travel and the less stiff downwards travel with the dual rate. These things give awsom travel but they must be unstable with all that soft downswards travel????
And the single rate coils does everyone run them unrestrained to get extra droop from the springs coming unseated (given that the shocks are long enough) or do you tie them in top and bottom for more stability and less travel.
