I wasted some time this holidays building an excel spreadsheet for suspension calcs.
It calculates and plots suspension arm & axle location for a combination of bump and roll.

The current version is for twin trailing arms per side, with a WOB link for lateral location. I'll be adding an option for watts link instead of the WOB next.

If this is of interest to anyone, I can make it available via email / Dropbox / whatever.

I'd need to think about that.
The WOB and Watts link have a roll centre that's fixed to the chassis, which makes the modelling much easier.
Mumford roll centre changes with roll, so I'd probably have to redesign the spreadsheet to account for it.

On the other hand, I got bored with it, so this may get me enthused.

I have designed and built my own Mumford link in my MGB track car. Works incredibly well.
Previously I used a panhard rod. I thought the mumford roll centre was where the line of the links meet?
