Does anyone else have any excessive chassis flex? I have the Prospec and noticed that the rear tension mount was cracked and ordered the aluminum one to firm things out, but it still flexes around the center diff. Is there something that I am overlooking? Also have the one-piece mount. I had another MBX-5 not Prospec and it cracked an engine case where it mounts to the engine mount off a hard landing and now I am guessing that chassis flex may have done it in. Any one else out there with similiar situations? Thanks.
