Back in the 4 thread I remember Jason commenting/recommending lighter front diff oil as I think he ran 80k in the front at last years Qlds, may need to go find if I remembered that right.
Although if I'd just listen to Trev, it's likely I'm still just not getting off the throttle soon enough, but damn it I still want to get 'into' those corners faster.

(And I know the Photon does it, so why can't the Mugen)
It's the track that's us hindering a lot, the only time Ive seen 200mm respond like an electric has been at Miami Worlds. Our bumps in conjuction with the track layout make for considerable compromises.
Your photon is probably well under weight, and is so soft it manages the bumps. Put that configuration on a nitro like I tried with the V10 and the car was awesome until we needed to go thru the sweep and long track where ther car pitched over and the inside wheel rose and the diff started to spin up. You could try for much softer setup and stand up the shocks, more ride height, stiiffer sway and more droop in effect to try and get a similar setup.
Trevor telling you not to drive hard into the corners, I said with too much steering rate you will naturally have to drive in harder and force slip to understeer to get a smooth line, heavy diffs will also wash speed as well. So it's hard to do both, perhaps try a REALLY SOFT setup and avoid the sweep to get some benchmarks. Jeff drove Guy's with the soft setup and it was really nice, but just wouldnt work for the whole track.
