short camberlinks make the car very responsive, in long sweep corners and high grip it's to twitchy, for that it's better to lengthen the camberlinks or remove shim under the ballstud.
Ackerman, i think it has more influence to the speed of cornering, (correct me if i wrong), low grip conditions more ackerman, more forgivin. less ackerman (forword possition) more responsive and more mid and exit cornering.
