I reinforced mine with a couple CF squares at the bottom/rear two mounting pads.
I still get some side to side wobble for the wing I can see over bumps in the rearview, seems to be more from the hatchlid than the mounts, though the mounts do have a tiny bit of side to side flex.
It's a whole lotta wing for the price, and has transformed the car's handling on track. Would recommend for anyone wanting aero.
