the way i see it is arm sweep is generally moving the end of the arm backwards,this will give less castor,shorten the wheel base,and affect ackerman,so will obviously affect the car in a big way,so why use it if alot of other settings are changed?
this is taken into account when setting up the car,but what i really want to know is what it actually does,and why it does it,is it just a mod thing as i only run 13.5?
if you do use arm sweep would you move the shims around to get back to the original wheelbase and ackerman leaving just the castor with arm sweep changed?
