My points are as follows: Their are reasons that the newer stuff(2016+ ruffly) is better. The newer chassis' not only have the increased right front clearance, but chassis setup technique has changed too. The new stuff is not dependent on static scale numbers. With the new stuff, you may have to put it on scales and set some ride heights, but this is not where the secret stuff comes in. The secret stuff has to do with the load numbers on the right front and also the load numbers on the right rear. The load number that is commonly worked on the right front is a number that is determined at 4-5 inches of travel. These load numbers are set on a spring smasher, and most all of the guys running this newer stuff will have the spring smasher machine with them at the track. These measured numbers at X number of inches of travel are much more relevant than any number that could be found by weighing a care at ride height on 4 scales. I am not saying that any certain chassis cannot be modernized, they all can. Someone said that a chassis is just steel tube that has been welded together, and this is true to a certain extent. If you are trying to run an older chassis, you must realize that although the chassis can be made to get the rf travel that a current chassis can achieve, you will not be getting the help that the other guys with these new chassis are getting. Very often they can call the chassis company after the heat race and the support guy will give them advice on what their right side load numbers should be. You will have to make your own setup decisions. By buying a current chassis, you are getting new steel, but most importantly you are buying know how. This know how usually comes from a top 30 driver, and he is beeing helped by several engineer type guys.
