Traction loss into 2nd would definitely be because of the ZF tune, there is no slide in the gear changes, it just goes straight in. At lower gears theres a bit of a clunk, pushes you back into your seat a bit, but it is awesome at higher gears. When full throttle and changing gears at higher revs, it almost feels like you only have one gear. Seems like 31s are better than the Conti Sport 2s Didn't get the T/S Loop, nor the battery isolater switch which I didn't realise I needed, but they let me run for the night as I had the harness. Only broke 11s once though, fml.
