That's the correct one, 46u, I got mine at New Era models along with the wing. Both are on the MT2 hop-up page. I'm not sure if it will fit on the MT, as the shock towers are different from th MT2. My brother-in-law has an MT, the towers look similar to mine, but they don't look as beefy. I'm sure they could be made to fit with minor modding. 46u, do you even run the MT towers, or have you switched to the ones for the MT2? To get the wing to mount correctly, I had to dremmel a flat spot on the X cross brace reinforcement area on the shock towers. The X comes to a point in the middle, this is the area I ground flat so the wing mounting plate would fit flat against the shock tower. I only had to grind off alittle, so I doubt much structural support was lost. The wing works great, keeps the butt on the road in high speed runs and improves overall stability. It adds some weight to the rear, but it isn't much, really. The handling characteristics while jumping changed slightly, but not much. It is still mostly hands free while jumping, but now has a tendency to nose down after the apex of a long jump, due to the weight in the rear making it do a slight nose up on takeoff. After most of the inertia has been lost after the apex of the jump, it noses down slightly. This is countered easily and still very controllable. It had this tendency before the addition of the wing, it is just exaggerated alittle now. The extra stability is worth the extra weight, IMHO, plus it looks bad a** and who doesn't want that?!
