I could jump up and down on my back bumper and get quite a bit of movement out of the rear suspension. I'll see how it goes on the road like this befor changing it. At least it might give a comfortable ride because there's not much give in the sidewall of the 17" tyres.

Also remember by moving the lower shock mounts inwards to clear the 11" rims you have increased the leverage the lower arm has on the spring. These small coilover springs are pretty cheap to get made anyway.

I'm running a single rate spring set up with a fairly soft tracking spring that you can squash flat with your hand. The tracking spring just keeps the main spring on it's seat at full extension.
This is the setup that Ian used before the dual rate spring setup. Don't know how it'll work I'll have to wait and see.

I agree with Phil on the body positioning. You might have to touch up the holes in the body to get the alignment on the chassis sopt on.

Cheers
