shock length and angle are a very nice adjustment.the shock length plays a big part in how quickly and smoothly the weight is transfered and how smoothe the rear pod rotates in compound movements of front to rear compression and side flex.a shorter center shock seems to quicken the reaction of the car as a longer shock slows it down.a shock that is too short will react too quickly and create a twitchy push.i normally start short and increase the length until i am happy with the feel of the car.you will notice the change on corner entry for the most part.when you go into a sharp corner coming off a high speed straight and the car has a push to it or double steers,you can increase the length of your shock to slow the reaction down a little.what is happening is your weight is tranfering to the front of the car very quickly and then being releaved before the car sets into the corner.this is the reason why i have a long and short antenna mount position on my car.i found it to be a real good adjustment for different track conditions.shock angle is also a real nice adjustment.i use this adjustment to manipulate the amount of off and on power steering i have.i raise the front of the shock for more on power steering and lower it for more off power steering.you adjust this to get a good balance of on and off power steering and you should be set.hope this helps.
