Wishbone Material

[SteveMX5]

Hi This is my first post so please be gentle!

I am coming to the end of building the chassis for my MX5 based roadster using the Saturn (or NTS?) plans (with a few tweeks). Looking forward to the next stage which looks to be the suspension wishbones.

Maybe I need to go to specsavers but I cannot find any specs for the material used for the wishbones apart from the obvious dimensions. Do I need ERW or seamless and what wall thickness?

All help greatfully recieved
Steve
