Caster setup & adjustment
Discussion
Hello all
My car (2000 model, K series) is a quite twitchy in road use and sensitive to steering input. Maybe I just need to have more finesse with my inputs but just looking at the current suspension setup I see (if I understand it correctly) that it's setup with minimum caster. That is all 4 washers (approx 1mm width) are forward of the lower wishbone rear location. I think I've read that the standard setup is 2 washers either side of the joint.
Can anyone say what the general handling traits would be for my current setup Vs the standard - in terms of stability, steering weight, feel, camber change, etc. Also if I were to change to standard setup, I guess I need to add washers of same size to the front wishbone joint.
Thanks in advance for any advice.

Hi all and thanks again for info. I appreciate that other aspects like toe, camber, spring heights, tyres, etc. will also influence significantly.
I've got what appears to be supersport/lite suspension spec (adjustable platform all round + rear 4 position anti-roll bar) and running A021 tyres. I most likely need to take it to be professionally setup for my needs, but on seeing the caster figured I could adjust that initially myself. The rear anti-roll bar (looks standard type, no colour codes) was on stiffest position so I moved that one position forward. Although this has given me a little less ulimate front grip so a bit of dynamic negative camber change wouldn't do any harm.
It could well be that I'm simply getting major tramlining effects on more uneven surfaces due to toe / camber settings. So I'd at least want to get those properly measured & set.
BTW I'm in North Hamps, nr Basingstoke. Regards.
