These images were just grabbed randomly via google image search to show how other people had sketched dimensions. However the Locost community in general have lots of discussion about suspension design as they tend to customise their DIY, built from scratch designs using a variety of donor parts.

http://sevenesque.com/plans/ (McSorley's site has lots of plans and DIY suspension fine tuning without all the maths advice)
http://www.super7thheaven.co.uk (lots of engine fitment, radically different ideas)
