Hey all.  
So there has been a decent amount of discussion between some of us about how to get that extra bit of pace out of the car.  It's no secret that there is a group of skippy drivers in iRacing (looking at YOU Justin haha)  that are very very fast in this car.  The general consensus from us regular Thursday series plebs seems that it looks like fast guys "drift" the car around the corners.  I myself even alluded after last race that I stumbled on a way to make the rear end rotate mid corner, giving the feel of good cornering.  In the back of my mind it has been bothering me, since drifting the car doesn't gain time via the delta bar (for me), and also doesn't make much sense with the general "smooth is fast" mantra this car holds.

I did a bit of reading, and found this post in the forums.  It goes into the tires, slip angle, contact patch, etc.  The jist of it being, fast guys only LOOK like they are drifting the car.  They are in fact just very good at using the tires to the maximum of their potential.  There is a small amount of slip and yaw angle that will occur at max grip efficiency, making it look like they are sliding through a corner.  There are (I hear) 2 ways to get better at maximizing the grip you have available.

     1- Listen to the tires.  Tire noise, or "squeal" is good. you are close to the limit of grip.  Tire "screech" is bad.  The sound changes when the amount of slip is high, and you start losing grip.  Turning the engine noise down a bit and learning to listen to the tires and experimenting will show the difference between the sound you want, and the sound you don't.

     2- Force feedback.  You can (apparently) feel the loss of grip quite accurately in this car.  You don't even need a high end wheel for this, as Ian Bevan (4th post down in the link I posted) claims he had good results with this G27 wheel in this regard.  If some time is spent fine tuning your FFB on the centripetal skidpad, I could see this being very valuable on the track for your feel of the car.

So to sum it up, no, I don't believe anymore that there is a secret trick we are missing to get the last second out of this car.  Just gotta git good son!  Full disclaimer, I have not done enough testing with this information to verify it myself, but it is posted in the beginners guide on the official forum, and I believe it to be true.  It won't be a magic switch for anyone I imagine, but at least something to start paying attention to to help gain the last few tenths.

Sorry for the long post, but I though Paul might explode if he didn't figure out how Justin was doing it haha.

I figured out the tire squeal thing at Okayama. I thought I was locking up... Until I actually locked up. Found that extra second...

Good post.

Thanks for sharing this. I'm always worried that I'm pushing the car too much when the tires start squealing. I can typically feel when I'm sliding and losing grip. Just that delicate balance of pushing the threshold but not exceeding it.

Switching to full manual really helped me get a few extra tenths. Will have to start looking at other things to get over the next barrier.
