my buggy came with the updated arms Hyper. they have just released another set which i don't need cause the original set hasn't broken yet. the geometry on the new set is the same, it only has another support through the centre. get your facts right before you start hacking on me. have you finished a race with it yet? i know the answer to that so no need to reply. i was erep-lying to a comment saying everyone with a mugen upgrades all their parts, i clearly haven't so i don't know what your problem is.
