Go for Simmatch GT1 aluminum rig, i'm also using it because its the most proper driving rig that could grow and flexibility to add extension and lots of universal mods.  The 4080 aluminum quite sturdy too and no torque twist as i seat around and pulling the steering.  I've added lots of tactile/vibration/rumble system around the rig and holds the 'shocks' very well.  Really feels like driving a real car in VR since i can feel engine vibration and road bumps and rumbling all over my body through full aluminum frame.
