i have a b4 buggy and realize that there are setups available that are made by other people.my question is this;could someone explain how these people come up with these setup?trial and error?i would love to know what changes what!also is there a best setup for ultra slick hardpack dirt?my car has a 17.5 motor and barcode tires on it now.i thought that in really slick conditions a short pin was best?also what suspension adjustments for slick?
