Awesome video, that looks like a lot of fun.


1) throttle extensions that attach to the plate to allow easier heel/toe
2) Nope. Anyone know?
3) Maybe. He's a really talented driver regardless, though. I thought this technique he mentions in the comment section was interesting:

[ It's actually part of the trick of making these Hoosier R6 "R compound" tyres turn their best lap when they are brand new. They are a bit squiggly (compared to slicks). But if you look at lots of my corners I use a rather aggressive turn-in, the back end starts to break away, I counter steer a little and then continue turn-in again. This is not an effective technique for racing as it is very hard on the tyres. But for quali/time trialling it is very good for turn 1-2 fast laps. ]

^ I was wondering about about the corrections mid turn, that explains it, thanks!

AP Racing Sprint BBK with XP12 all round worked great for late and hard braking...and the Jackson Racing SC worked great.

Thanks for your suggestion @CSG Mike!
Glad it worked for you

Let us know if you're considering anything else for your car!

There is a spot where you can apply this approach at SoW going CCW, I do this in GT6 in a bone stock '12 FR-S seems to be the fastest way around there. If only I had the 'Ca-hones' to do it in real life. IF you dont slow down fast enough you will get launched out of a banked turn sideways. Should be worth some good air time. lol I seem to be about 13-15 seconds faster in GT6 than real life with better tires and alignment....
Hell, no I start wide for T1. The few hundredths is not worth it at my level.

Double apex sliding into the bowl is the fastest line, but yes, if you miss it, then you launch off sideways...

What's your T6 apex speed? You should be at 85+.

Your T4 should be flat without lifting at the top of 3rd/bottom of 4th, and T5 should be just a very light brush on the brakes. T6 should be a brief lift at most.

Dude looks like a older Jorge Lorenzo. Fast like him too.... Also he is jabbing at the steering way more, telling me he is pushing the tires HARD. Am I wrong with that assessment?

I hear hitting those red curbs cuts laptimes like hot cakes.

I tried 85 once but spun out at T6, also tried flat out T4 and no bueno... This is with Rivals will see if NT01 can do better

You have to balance the car in T4, but it should be doable with the right line, with plenty of track to spare.

Make sure you ARE using the berms; they give you an extra ~5 feet in turn radius.

T6, you have to steer in for the dip, and then ease up on steering as you come out. Take advantage of the track surface.

It's difficult trying to interpret what's happening from these videos, but here's what I see: The Stiglet (heh) turns in earlier than you, is on a "flatter" approach, and is describing more of a parabolic line than your more rounded line.

Stiglet's line probably allows later braking, and because it's so flat (nearly straight), he can brake harder down into the apex and carry more speed than you up to that point. His parabolic line appears to use less road out to the right at mid-corner compared to your line.

This appears to be one of those corners where one does not WANT to use all of the available road.

At the "pointy end" of the parabola, Stiglet makes a sharper turn, mid-corner, than you do. Observe the amount of steering lock that he needs to dial in mid-corner; it's much more than you (and I doubt that's all attributable to differences in your respective steering rack ratios). That engine hung out behind the rear axle probably helps him flick that thing around briskly. The trick (as always) is to keep that all under control and pointed in the right direction.

Stiglet makes this into a sharper, single radius corner, while your approach makes it into a 2-part decreasing radius corner.

So? What should you do to try this?

Turn in just a bit sooner on a flatter trajectory down towards that first apex. Get that left front wheel right down there. Take it slowly, though, because now you've got a shorter radius turn (sharper at mid-corner) to get it headed back towards your second "apex." Start ridiculously slow, and then work the speed up. At some point you should feel that you've reached a happy compromise between the sharper mid-corner turn and the benefit of carrying much more speed down into that mid-corner flick.

I see it as the REAL APEX is out in the center of the road, mid-corner; you just happen to clip the borders of the roadside on the way into and then out of that corner.

If you find you're dropping a wheel off into the OUTSIDE dirt at midcorner, I think you've charged in a wee bit too fast, so slow it down.

You don't want to find yourself sitting upside down in the dirt outside 2-3, hanging from your belts, and saying, "Oh, okay..."

Yeah, that's what I was thinking. Really hard on his front tires, generating a lot of understeer mid-corner. I could see the fronts overheating and going away after not many laps despite the lightweight front end on those 911s.
