Subframe construction

The body of the kart will be constructed of a 3 part aluminium frame on top of a 50mm x 20mm subframe for strength. The steel subframe is welded to the newly widened Drift 2 front end, with a 50 x 20 cross member at the rear of the frame and two tringular brace pieces welded in to prevent diagonal movement.

A riveted or screwed on floorpan, or some X members, even alloy ones, would add some lateral stiffness. Obviously the engine supports and seat structure will help at the rear. Cheers, Daryl.

Cheers Daryl, yes there is an aluminium cross frame to go between these rails - to be the subject of the next build page. Gary
