Vid covers part of my favorite section at Sebring. From Cunningham (T10) to exit of Le Mans (T16) is fricking bliss if you get it all right.
The alpha chassis is stiiifffff. Much closer to the M4 end than the Corvette.

Agreed. Bishops bend is definitely the best part (Turn 17 is sick in its own way too) - was doing a couple of cool down laps with a buddy riding passenger there. I think I got up to 124 at Bishop's on my 2:20 lap but I know there's more there.

+1 on Comfort mode steering at the track. Part of it for me was that for some reason in the other modes, my brain/hands would perceive the increased steering weight as the car wanting to push, when in reality of course it wasn't. The lighter feel I think has allowed me to feel comfortable with higher corner entry speeds. I just got the B16's installed (holy stiff Batman) -- anxious to see what these can do...

I couldn't use any other steering setting. In the other settings, small inputs would destabilize the car and make counter steer 100x harder.

Interesting observation... I wonder why this would be? It was my understanding that, assuming the amount of input was the same (i.e., the same amount of arc traveled by the steering wheel), the amount the rack moves and thus the amount of turn by the wheels is the same regardless of mode (i.e., it is simply the "weight", or resistance to movement of the steering wheel, that differs among modes)

The weight and rack speed change with each setting.

Very interesting.

Had an off in the last session of the day at PittRace, which after extensive thought I am attributing mostly to end of the day exhaustion - and possibly also to the steering being in Sport. Always drove in Sport until recently, felt "better" or more "racy" but then again, I recall the client advisor when I picked up my first F80 in Munich in 2015 specifically set up my M2 settings for the Nordschleife with steering in Comfort. He said it would make it easier to catch the slides - didn't give it much thought at the time.

I've been exclusively driving in Comfort for the past few weeks just to get used to it. Can't wait to try it on track.

It made a huge difference for me. The confidence it builds made me push the car harder and faster too. I avoided it for a while because.. well how can you track in "comfort" mode?! But yeah, I had 1 spin at Thunderbolt, 1 spin at Pocono Infield and 1 spin at Lime Rock (just past the crest of the hill - close one). All three times I was in sport steering. Never lost the car in comfort, even felt comfortable sliding out of the toe at the Glen which used to scare the shit out of me.

Driving with comfort steering on the track, I’m glad to read this from others because this is my choice 100% of the time.
A change in steering feel is usually my first sense of the rear end coming around.

Beat my PB at Willow Springs by 4 seconds at 1:38.45. Still not where I want to be but it's still an improvement! Goal is 1:35.

I had a seasoned NASA champion drive my car to see what it could do with a real driver behind the wheel. He did a 1:33 going 8/10ths AND running out of gas on the front straight (oops I forgot to check it). He confirmed a suspicion that I had. The MPHAS is underdampened. Willow Springs turn 8 has a 115mph sweeping right with lots of bumps. It's terrifying because I always feel like the car wants to hop hop hop right off the track. He agreed and said it wasn't confidence inspiring. Now I want to upgrade my suspension without breaking the bank since I'm returning the car at the end of the year. Any suggestions? Used Ohlins?

does it really make sense to upgrade a suspension for a car you're returning at the end of the year?

I ask because I have the same thought, although my plan was to sell next year for something new.

I want to set some PBs with this car before I sell it and a MCS suspension will take me there, but does that make sense if I get rid of it next year?

If I can find a nicely depreciated used set...
