just wondering if it is best to turn the rear shock all the way up or hard or whatever. Does this help or do u actually have to tighten the spring? if so how do you do that on a 03-04 636? thanks in advance for any help

 

tighten the spring till there is no sag in the suspension then set shock to hard on both setting's ...awsome for stoppies and circle

as far as how ,loosen the top spanner nut on the top of the spring then tighten the bottom one then retighten the top one to keep it from backing off

you can use a hammer and punch but a spanner wrench is the easiest way but loosening the top one is probably easier with a hammer and punch

 

does this really help out that much? Maybe i should try?

 

yes .
