This is a great article SUP73 but you should update your #1 POST with the links. they are all dead or missing links since 2009.
Understanding suspension setup for drag racing is just as important as it is for F1, Indy, SCCA, and any type of road racing car.
If you dont get a setup to work to get all your POWER to the ground and make "traction" then its all for nothing. The transfer of power to the track surface is what its all about and the suspension of your vehicle does this.
Airbaggers, lowriders, slammers, draggers.... this does not apply to you even though many of you make some incredibly nice suspensions in your trucks to do no work at all other than to go UP and DOWN ....
