Chassis: Overkill?? not enough?

[Mark B]

i wasnt sure just plate would be enough, most cars ive seen have got pretty much the same as ive done, but thinking about it i could replace those members with some thing much more usefull (and triangular). and the sva manual reckons that would be ok.

What do you mean triangular???? Surely plating across in Ally or Composite sandwich will be fine. All sevens (I think) have a space frame with an aluminium floor section?? This is usually fine!?!

i agree, but it needs some sort of frame work under there, if not for the seats to bolt to then at least as triangular bracing to increase stiffness in that area.
