Default Expert help needed- caster adjustment

i need some advice on the following:
I have a CS2 PDK.
Running 7mm spacers front+rear and GT3 lower control arms.
Camber is 1*20' front 1*50 rear
Caster comes out 8*20'

My problem is , although the car is very balanced and behaves as i want it to,
the steering has become much heavier requiring more effort and has also lost some of its self centering action.

I an using the middle hole in the LCAs

What is the culprit?
Can reducing caster make steering lighter again?
If so how can I reduce caster?

new LCAs should not make steering wheel tighter to be turned. to answer directly to your question if you want to adjust castor then you`ll need to put on new adjustable front fork arms - something like these.

but i suspect you have some other issue.

self-centering force was due to excessive toe settings. if you went close to 0 toe for performance your self-centering force went away together with excessive tire wear. but it may be something else too. i would check with mechanic who did the work. your current castor is fine, that is close to what i have. more the better.
