User license agreement

You can:

  • A user licensee permits you to run an unlimited number of cases on the original licensed machine
  • Design suspension systems for hire or run cases for your friends
  • Publish results of calculations on the net giving appropriate credit to www.ShimReStackor.com

You cannot:

  • You cannot install the software on a second machine, give away copies of the code or implement interfaces allowing unlicensed users to run the software
 

ReStackor Warranty

ReStackor attempts to relate the vague concepts of suspension ride, feel and behavior to the harsh cold numerics of math and physics. On that boundary of math, feeling, emotion and suspension "feel":

  • There are no guarantees
    • If that is beyond your comfort zone, back out now
  • There is no warranty
    • If that is beyond your comfort zone, back out now
  • There is no support
    • If that is beyond your comfort zone, back out now
  • There is only sweat and hard work
    • If that is beyond your comfort zone, back out now

For those willing to cowboy on in the relentless pursuit of pushing suspension systems beyond the state-of-the-art:
