I may be building my own rig with extrusion aluminum and found a 40x40 option that is 1000mm (1m), wondering if this is long enough for the 2 base beams of the rig in length. I am 193 cm (6’4) and drive in a gt seating position. Also, the set comes with 4 pcs, is 1 meter too long for the wheelbase stand or can I use those there?

Thank you
