I think the basic geometry is the same as for a TR3. I was curious to
see how well 3/16 agrees with the number in the little report I wrote -
http://www.tildentechnologies.com/downloads/TRsuspension.PDF. The
formula gives a 0.174 in/deg, which is very close to 3/16. I was
rereading that stuff I did back when I reworked the suspension on my
TR3. It's been so long I don't even understand what I wrote, so it's no
wonder no one else does. It does have accurate numbers for the geometry
measurements though, so it could save time for anyone wanting to look at
suspension mods.
