I had a bunch of fun at the 86Cup event - it was nice to dice it up in traffic a bit, met some people from Discord, took a couple of passengers, and was able to donate my spare CV shaft to a fellow 86Cup person so they could wrap the day up.
One of the sessions I took a passenger they got the real swap car experience. First flying lap the MAP sensor decided to pop the bead of RTV retaining it and strand us just off track after the double left (turn 6 counting cw).
I ran the car on RE71RS and the ~220whp high power tune since I could, but I left a bit on the table in terms of driving and how hard I was pushing since there was nothing to win. Couple of laps here, a 1:57:3 and a 1:57:4 while chasing a new M2 and a 991 GT3 Cup. I can do the same lap time on the 200whp tune and RC1s, but it was easier in that I could leave more on the table for the same lap time.
Car feels dialed. On the RE71RS side of things I got to form a bit of an opinion:
* Out lap and first flying lap on a cold track they're sketchy
* Maybe half way through the first flying lap they start coming in
* I got two or three good push laps before I'd get one big slide which was the sign to back off like 30%. Before I figured this out I had some ridiculous full lock oversteer in places I've never had oversteer in my life like the right as you go up the hill after the bowl and the following left before it goes downhill.
* They've got a sharper grip plateau than RC1, the RC1 is easier to drive
* They need less camber than the RC1 by a decent amount
Basically, the RC1 gets pushy and slow when you overheat it. The RE71RS gets greasy and snappy.
