Light Racing UCA Question

So I had a alignment done and my caster was +2.9 left and +3.2 right before alignment. Control arms are on the "D" setting before and after alignment. Now my caster is +2.4 both sides. I would like to change the setting to "E" or +3.0 my self because it seemed to be a bit smoother. If I change the settings will I mess up camber or toe?

Thx

Yes you will need another alignment

 

Ok which is better the Sport UCA or the regular style? all I know is that the uniball is exposed on the other and on the sport its enclosed. Is there pros or cons on getting on or the other?

 

From what I heard is the uni ball will give u more articulation? And is $200 more.

I think u will have to remove the arm to replace uni ball... Light racing u don't.
