Re: X series front suspension
I realise that the shims are not for general alignment but most falcons I've pulled apart have had some shims under the upper control arm bolts, its my understanding that these are there to make up for tolerances in the chassis, I'm just a but sus that this ute dosent have any.
The panel beater took the ute to a competent suspension place, they do most of the race cars, and it was their suggestion to shim the upper control arms in order to recover the camber settings. I was wondering if anyone had played with shims to correct problems and how successful they were. In my previous ute I was able to run 225/60/14 tyres on 7" rims with no difficulties and get a reasonable amount of caster so there was a difference somewhere.
I'm aware of the implications of guessing my wheel alignment settings but if I've got to drop the upper control arms I'd rather do the work myself and then take it to be aligned than drop it in and get a $500.00 bill for "black magic" even if it works.
I dont understand why shimming the front locating bolts on the upper control arm would make the caster more positive, wouldnt this have the effect of moving the top ball joint ******d and rearward which would increase negative caster and also affect camber which would have to be adjusted via the lower control arm to compensate or am I barking up the wrong tree altogether??
Thanks for the reply,
