Following previous post, I did for the moment the
following document for off-road. I have two other for pan car and TC but maybe less interesting for people here.
There is all brands/manufacturers I know but maybe some are not listed, some data are missing also especially some rates/weights for Tamiya spring just get the color which does help, there is some part numbers too.
The other concern is how to watermark it correctly but will be sorted later.
If you could provide feedback and additional data, that'll be great.
