fancy giving the 90 extra travel, but without raising it.
 seen the scorpion racing evoloution kit but they want £450+vat :shock:
 Any one know what individual componants i would need to give extra travel? or if indeed 2" extra drop makes that much difference in traction?

anyone?

If ya lift it 2 inches you should extend the bump stops and what you gain is slight droop and a whole load of body roll and a higher center of gravity.  To my mind the only reason to lift is to clear big tyres.

i quite agree jim, which is why i dont want to lift it, but do want increased axel articulation to help maintain wheels incontact with the ground.
 thats the theory of the evoloution kit, but not necessarily convinced by the price or how well it actually works

I need wheel contact wi the ground, you got traction control so you are fine LOL.

A set of 1"oversise springs would lift it but if you go over 1" there are other issues that will need sorting,would't bother personally unless your getting serious off road.

extra articulation is all down to shocks and front and rear radius arms but is dependent on a number of things.

To get extra shock travel you can either get longer travel shocks or lower the shock mounts front and rear. Both will cost you roughly the same.

You need to make sure that you don't over compress the shock when the axle side that's going up, goes up. How you stop this is by extending bump stops. btw Stiffer springs often used in lifts often achieve this too, and can actually restrict articulation.

Longer shock travel means the axle will now go down further, but now the articulation is limited by the radius arms. The rubber bushes compress and deform quite a bit but only so far and on the front especially the articultaion will be hindered by the radius arms. This is why so many challenge trucks fit kinked radius arms front and rear. It's the same reason why people put 3-Link suspension on the front.

With the extra articulation on standard springs you will also need to allow the springs to dislocate. To do this you can use some re-location device, there are various available, cones etc.

Lastly you will need to extend your brake hoses to allow for the extra length between the axle hub and the chassis.

Not so straight forward is it :lol:  :lol:

Cheers

Steve

Umm, no, But does explain the extended bump stops in the kit, the rest i had just about sussed.

 cheers steve, maybe give it a miss unless i really need the extra. :(
