The car was very composed in corner entry, mid, and exit.

-Full steering travel and -5 expo on the Tx
The car is balanced with each corner registering at around 310g (give or take 5g). With the LTC-R regular body (1 coat of paint and no decals) comes in around 1360g. The car is pushy (overall) so I'll be working to get a little more steering from this point on. In terms of durability I've not had any issues with the upper turnbuckles, front universal ring, etc. The car did get 'tweaked' really bad after a run in with another car but was resolved by resetting the upper deck. Of all the cars I've driven and bad accidents I've been involved with I've never seen a car come off the track that 'tweaked'. So far the car is very easy to drive and very consistant throughout the race. I'll need to work on the various shock dampening and spring rate at my next outing. I still haven't found the combo that feels similar to my TRF417 setup.
The C is a very unique track.
I would try front gear diff, move battery forward and droop of 3F/4R there. Had a really good runs with the T car there. Also go with 1d toe out in the front & try to disconnect the front sway bar for a run. Also can probably reduce the rear toe to 2.5.
