Simple yet stable enough pedal mount, should fit most of pedals with pedal plates - 57 Lite Pedal Mount

Goal was to use as little as possible elements and have versatile high adjustable pedal mounting point. 

Designed to work with sim rigs with 500mm between lower frame sides, compatible with my 5780-LT rig.

I used this mount with Fanatec V3i, later was extended with 3 full size bass shakers - quite stable and no flex.

Provides enough forward bracing to open front rigs like the 5780-LT. If you are going to add motion additional cross-support is needed. With simple addition of 1-2 extra cross profiles can be extended to accommodate standalone pedal + separate heel plate.
