Not Ranked
Thanks for the suggestion Les
My last trip under the car on Saturday was to pull the diff - only spent a small amount of time looking at the upper arms.
Considering adjustable upper arms a-la factory five but that requires planning - whereas access to a nice slab of steel, a cut off wheel and a mig does not (not much anyway)
Would anyone like to check my maths for how far inward I would have to move my upper arm mounts.
I think that if I wanted (say) -3deg and the wheel is currently at 0deg and the upper arm is 196mm (8in) above the centre point of the front wheel I would have to move the top mount in by the result 196mm x cosine of 87 deg (0.0523) = 10.2508mm
Am I looking at this the right way?
(kinda makes my brain hurt - my have to consult my local New Zealander).
