Not to make new post, I think is the good practice to mix square and round tubes. This could lower a wieght a bit and increase stiffnes. At least this is my goal to make when my build will start. Main structure 25x25x2mm and all braces and other with round tubes + some reinforcements.
My only consideration is if the roll axis and other performance bits change significantly if i will use MX5 front uprights, wishbones modded for that and rear sierra ones. I plan to use zetec (tuned to 180hp) with t9 and sierra diffs are way cheaper than miata. Coz i doubt that its possible to mix miata rear uprights and driveshafts with sierra diff.
cheers
