Default shafty suspension...

looking to get some ideas on suspension setups. currently im using a external/internal spring w/80wt. 3 hole piston. the internal spring seems slightly softer than the ex. the rig is almost 5lbs. the axle will drop out a few mm. bout 4.5mm. im thinking since both spring rates are so close in tension-my suspension is very neutral(in front)...but slow. do the springs need more variance between them or thinner shock wt.?

ax10 stock chassis
mirrored trans. (i'd have to say the single best anti tt mod to date) thanks EeePee
alum coilovers 108mm
4 link f&r
2 1/4 chassis clearence (belly dragger)

thanks.
kurt

The speed of compression of the shock is controlled by the oil. Try a lighter weight oil if you want them to respond faster.

you may have to play with the triangulation of the upper and rear links, im a little confused on what your wanting, if your just wanting to get your suspension set up a little better id defnitly ditch the 80wt for some 30-45wt 80 is SLOW, but then again you are running a 3 hole piston so like some 55wt or 60 might be good, but if you showed us a pic we could help a lot better

well, got out yesterday...still no video, what seems to be the issue is;on flat or flat style crawls the front suspension will flex. but on incline it tends to rely on just her rear susp for all her movement. the fronts seem to always float over gaps. could it be that the external/internal spring rates are too close? too far? in relation and are cancel'n each other out?

Yeah your front shocks are too stiff,,softer spring rates or remove the inners and see how it is..if its still stiff change the outers,,,but 80wt IMHO is a bit thick for a 5lb rig.

Also whats you weight bias,,forward or rearward or neutral? where do you mount your battery?

you can also try a different piston with larger holes or drill out the holes one at a time until you hit where you want the shocks to be,,,change the mechanics of the set up it will be easier to record whats happening especially with different maunfacturers making oil at different weights than spec'ed

it's very front heavy. the internal springs were installed with the intention of controlling susp. unloading during side hills.
