You're right, I was speaking of turn 5, I didn't know turn 2 was actually considered a turn, silly me.
But yeah, turn 5 is horrible corner. As moot said, maybe I need to use some throttle under breaking to keep the car balanced; also sticking to the outside and taking a later apex might help now that you mention it.
That is why I included the map. In some cases, "Turn 2" is actually marked 2A and 2B. Wanted to be sure we were talking about the same thing.
I think it was Frenchy who recommended I treat the Skippy like a 70's 911 - that advice was perfect! Rule #1 = brake in a straight line. Rule #2 = if in trouble, gas it. Rule #3 = Do *not* apex early. Rule #4, 5, 6 & 7 = Never, ever, ever lift in a turn.

Turns 6,7,8,9 is where everything can go wrong, you need to have Godly control not to drift the Skippy through that section of the track. I'm sure you know this, but just one ounce of drift and you can kiss good bye to your lap time.
Admittedly, I have not been practicing enough on pure lap times, but I have run a couple races and finished, I think, 4th on Summit over the weekend in the Skippy. My average lap time was somewhere in the 1:25 range. I don't have a problem with 6-7-8-9 because the sim is fairly accurate in terms of how much grip is available.
They just have Turn 5 all wrong. In their (iR) defense, Summit underwent "updating" a few years back and the renovation was garbage. The track is constantly under repair and the different surfaces play havoc on grip levels. What they've coded in Turn 5 is way - WAY - too slippery, though - like it's 100% epoxy... AND wet. The Skippy (like a 911) should be able to dive into the turn, accept just a *hint* of trail braking and take second gear at full throttle in prep for the braking point at 6.
Turn 4 can be done flat out by the way.
I worded that poorly - yes it can - but I, personally, cannot carry that much extra speed into 5 and expect to be able to get enough braking in without severely unbalancing the car's yaw. That's probably more me than the car since, obviously, I'm brand new to the sim and still have a great deal to learn.
Now... what I'd REALLY like to see in one of the future updates is for them to add the Shenandoah circuit. Why they included Jefferson but not 'Doah is beyond me. That track is massive fun. Put "Summit Shenandoah Map" into Google and click images - you should be able to get a track map easily. Would be a real challenge - very technical circuit and they even have a replica of the Karusel.
