Call me mr picky, but you start your thread by saying "ive just had my suspension sorted." If its been sorted, why do you want to alter it again?
This is a very technical area that is, to say the least very confusing to the uneducated, including myself! I have to say that reading most of the threads on suspension just add to the confusion, although it is a relief to read an addition from some one like Nelly who clearly has a better understanding. Any adjustment made by ourselves is just guess work. Why dont we just leave it to the professionals, of which there are numerous reputable ones, its not that expensive either all things considered.
