1) Featured Product - Suspension Analyzer  Our very popular Suspension Analyzer does a complete 3D suspension analysis, including bump steer, Ackerman, caster gain, Anti Dive, tire scrub, Camber Gain and much more. Complete graphs and reports are included, and several other advanced features not found in other programs.  It has had many updates and features added over the years and is now v2.4C.  Version 2.4C was released in 2020, and it's newest features included:

1. The program now finds the Force Based Roll Center, which is more accurate than the previous Kinematic Roll Center.  A Preference lets you switch back to Kinematic Roll Center if you want.
2. You can now use a Jacob's Ladder for a lateral locator, or a Di Dion rear suspension option.
3. You can specify the CV or U Joints for half shafts for either the front or rear independent suspensions and watch the "stretch", to see how much the splines will move.
4. History Log allows for a new way to find and open files, where the most recent files you have worked with are at the top of this list.  
5. The History Log also allows you to specify several different files for doing graphs, letting you compare more than just 2 suspensions on a graph.
6. The program displays the spring, bump spring, and anti-roll bar forces.
7. You can enter shock dyno data and several ways to enter shock velocity data, and display the shock forces for these velocities.  Handling ratings will also be adjusted by including these shock forces.
8. A new "Watch Rows" feature lets you pick up to 6 of the output rows to be displayed directly under the drawing.  This way you do not have to scroll down through all the data to watch the outputs you are interested in as the vehicle goes through Dive,  Roll, etc.
9. There are several new and more accurate anti-roll bar options for calculating roll bar stiffness, including the new "blade anti-roll bar".

2) Automatic Valve Opener is Back We've located a new supplier for parts for our Automatic Valve Opener.  So we are re-releasing it (part number PFA-VO).  It will automatically set the valve lift and record data during your flow bench testing. It automatically finds the tip of the valve and zero's itself out. It then steps through all valve lifts listed in your test in Performance Trends' Port Flow Analyzer software. At each lift it waits a user specified stabilization time, then records the data and advances to the next lift point.
