Do the outside edges of your tires wear out first? This is a verytypical trait of MacPherson suspensions. Did you also know thatlowering your car's ride height tends to make the tire's edgeswear out even faster?

The problem is that the MacPherson suspensionon sports cars and production cars tends to produce a very steepcamber curve.
The high speed, tight corners of autocrossingdemands good suspension geometry. By improving your suspension's"curves" you can keep the tire from rolling under(which wears the edges) and help keep the full width of the tireon the ground.
PERFORMANCE GOALS
The secret to improving your suspension geometry is to achieve specificgoals for several suspension curves all at one time. Suspensioncurves that need to be addressed are the "camber"curve, "side scrub" curve, "caster" curve andthe "fore-aft" curve.
By achieving a specific camber curve you cankeep the tire flat on the ground when the body rolls during aturn, but this can be at the expense of directional control.Directional stability, however, can be improved by achieving aspecific side scrub curve.
The caster curve and fore-aft curve are twoseparate ways to create a characteristic known as"anti-dive." Only by addressing both curves do youreally have control of the anti-dive.
By quickly making changes to your suspension'sdimensions in the MacPherson Suspension Geometry software,you can see what happens to the suspension curves as a result ofthose changes (see example at right).
This is a huge time savings over the trial anderror method of making changes to the suspension on the car andthen reading and rereading the alignment gauges. Even if youdon't own any alignment gauges, you can still make hugeimprovements to your suspension using this software.
Your biggest advantage with the MacPhersonSuspension Geometry software is the ability to make informeddecisions about your suspension geometry. This technologyis still new and not yet common place in chassis shops. So, ifyou are looking for an advantage over your competition, thissoftware may do the trick!
This software also makes a scale model of yoursuspension as shown in the screen capture. This allows you toquickly spot input errors by seeing that the model does or doesnot match your actual suspension.
The really fun part of the software is that youcan use the up and down arrow keys on your computer key board andwatch the wheel move up and down on the computer screen!
Using the MacPherson Suspension Geometrysoftware is an easy and enjoyable way to improve your suspension.So, don't let the competition get ahead, order yours today! Usethe button below to go to the order form.
