I think here we use the same gear oil we do in the gear box, bit don't quote me. You can pull the lid and find out, but I am sure it is a liquid oil of some type.

So basically at any sort of speed the car is floating from one side of the track to the other even on flat surfaces. and requires a large amount of working the steering wheel to keep it in a straight line.

there is quite a lift in this rig and some intresting fab work but im trying to diagnose where to look for this problem i cant really understand what may be the cause of this problem as it isnt a constant one direction thing.

I'm banking on caster if it's a solid front end.

with a list of suspension and steering mods as long as yours
id say you have a long process of elimination before u get it sorted
it may be a combination of a whole lot of stuff

yeah checked and changed once it was fitted. I machined up a couple of correction plates and put them in so it was at a point that i thought it was right but it could still be not right.

not so much toe out makes it more stable but less toe in makes it less jittery, toe in the outside edge of the tyre picks up on surface changes so it darts around a bit, too much toe out will make it do stupid things as well though

lol at you lot and castor, my mini (therefore better handling and more responsive to suspension changes than anything here) barely changes with up to 3 degree of castor change compared to huge differences in the slightest toe or camber change, I really wish this internet rumour would die

its not the castor is the problem with fangs, its the leverage on the bushes and springs, if you stiffened up the bushes and probably even the spring so it somehow cant twist as easy so the same sideways load caused the same deflection I doubt you would notice they were there

yeah whod of thought anything that might make the suspension move up and down easier might also let the body move side to side as well
