In 1988 driving back to Robert's house from a race in Elkhart Lake, I started thinking that there had to be a way to mathematically predict the results of adjustments to the Spec Racer suspension.  This was in the time before the lower ball joint (camber) rod end existed -- and before the strut rod had a left hand threaded clevis on it.  So just to change camber was a big job --- and of course it simultaneously changed caster and toe.  I felt there had to be a better way. 

This was the genesis of "ChassisMan" -- a computer program I wrote in the late '80's that ran under DOS.  I sold it for about 10 years to several hundred racers.  Then we quit racing Spec Racers...and Windows and Y2K happened....and I never updated it.

Since Robert is racing a Spec Racer again, I've been meaning to update ChassisMan -- and the current COVID-19 pandemic has provided me with the time to do it.  So without further ado --- I present "ChassisMan Redux".  It does the math the same as the original, but with an updated user interface and file save/load structure....and it's free.  It's my gift to the Spec Racer community which has been so good to Robert and me.

Status as of 6-6-20
I still want some more people testing it prior to putting a link up on this site.  If you would like a copy as it stands today (I'm on version "0.18" as of this writing), send me an email and I'll send you a copy of the program.

Installation/Usage Notes
ChassisMan Redux runs on Windows 7 or later with .Net Framework 4.5 or later installed.  You'll need 7Zip to unpack the "exe" file.  You can place it anywhere on your computer you'd like (mine's on my desktop).  Windows Defender will probably object to it at first since I'm an "unknown publisher".  I don't want to spend the $ on publisher certification since I'm giving the program away.

 

Just tell Windows Defender that you trust the program and you'll be good to go. 

I also run Avast anti-virus.  If you also use Avast, the first time you run the program Avast will scan the program -- and will ultimately say it's OK.  I haven't tried any other anti-virus programs yet.
