Anyone who has built the rear end to book spec with the round tubes and then chopped it off
to fit grp (like i have) will probably agree that the design i have used is a much more sturdy alternative, that coupled with the fact that my rear stays are of a larger diameter and thickness than the book spec should be more than strong enough.
I am in the process of making my tank at the moment and once that is in i may consider some extra protection in that area but im trying not to over engineer things too much as i dont wanna end up at 700kgs on the weighbridge
