The sweet spot is "no movement".
From that point you can decide your diff setup: Only with syrup or syrup and mechanical tension.

High grip combination of tires and carpet seem like the second better.

Extremely low grip situations such wet are better tuned with the first.

From my experience, Stiffer mechanical along with 1 million, at least, for black carpet. Seems to keep the car accelerating even if it lifts the inside rear tire a little.

Agree with you.
Every driver who meet Black carpet, confirm that require a strong approach for best results.

I'm running 1 mil. I think I had diff too tight this weekend I couldn't get through corners without swapping ends even as the traction came up. I've backed it down but still with no movement and I will be able to test from there this weekend as the track wont be so busy

Some are using locked/pinned diffs on the black carpet. I tried it but didn't like the feel of the car. Still was fast though. Ran locked in my 12th with better results. Was about .2 faster per lap after I got used to the funky handling. Just wish I could get a gear diff light enough for 12th. The F1, I like the gear diff with very little action. A tip, right before you place the car down, rotate the diff to get the 1-2 million unstuck. I find the car does less funky things in the first minute when I do that.

Yes, this is also a good one. Just held a wheel and lightly hit the gas a couple of time. This will free up the diff from the first lap.

Or, before drive seriously, drive a couple of "tourist" lap...

What does this mean, will we able to source Fenix parts in the states besides CRC? I've been ordering from CRC but there are some Fenix products that they don't carry.

Right on the spot!
Fenix USA will not "take place" of CRC.
We've worked togeteher since day one and I'm extremely happy to cooperate with Frank Calandra.
Fenix USA will extend the parts range to the whole Fenix line.

Of course, as "Rome wasn't built in a day" it might take a little time to set up 100%, but we will do our best to it in the fastest way as possible.
