We take readings off the scales of each tire or corner. <br /><br />The car has adjustments that are built in so we can either move ballast ( the car has to weight 3400 #s and is useally light after the build) or adjust the ride heights (measured between the frame and the ground on each corner( useally behind the front tires and ahead of the rear tires where the frame is level front to back).<br /><br />We try to hit a base point of percentages for left side, rear, and cross (left rear and right front).<br />This base point is then recorded and adjustments can be made week to week to improve the car and make it easier for the driver.<br /><br />Example My Sons car;<br /><br />LF 816# 7 1/2 in      RF  812# 7 1/2 in<br /><br />LR 960# 7 1/2 in     RR  820# 7 3/4 in<br /><br />Left    1776# 52%<br />Rear   1780# 52%<br />Cross  1772# 51.9%<br />Total wt 3408# w/driver.<br /><br />This car has 350# of ballast (lead bars) that we can move as needed.<br /><br />I hope this either answers your question or maybe it&#39;ll confuse you even more...It&#39;s not an easy answer as you can see. Thanks for the intrest and asking.<br /><br />Later<br />Jim</b></i><!--QuoteEnd--></div><!--QuoteEEnd--><br /><br /><br />good morning everybody, <br /><br />Jim - I just showed thid to hubby bec. i knew he would be interested...he wanted to know what class of racing are you in involved with, type of car, what are you racing on dirt or payment?  etc....<br />what type of car does you son have?
