What should I be looking at or focusing on for my McLaren MP4-12C

If anyone else said they found the Carrera GT "easy to rotate and correct" I'd call bull****, but I know you are serious. As for the handling quirks, a fresh set of tires should suffice; then align and balance to spec.
If you're shopping for a Carrera GT, I caution you may wake up with a horse head in your bed until I find mine first. Nothing personal.

I'd love to try the new Michelin Super Sports to see how much that fixes the "loose" feeling. More grip certainly helps. But I still suspect that it's over-sprung for our bumpy roads (and is more optimized from the factory for circuit usage or Autobahn service). I felt it unweighting aggressively over humps and undulations that really unsettled or lifted the car. However, I bet on track with some R-compounds it's fantastic!
Has no-one ever inquired about spring options for the car? (BTW - this is the opposite problem I have with the RS 4.0 on track....it's undersprung).
Herr Preuninger are you reading this? =)

3. Lack of Stability control means you can't really push it beyond 6/10th - 7/10ths. Again - that percentage depends on your skill BUT I had extensive discussions with many CGT owners who track their RS's but weekend cruise the CGT because they are afraid of its quick rotation. The Michelin PSS's help address some of this but the lack of VSC is still somewhat of an issue. Sure you might say "A real man can handle a car without the electronic nannies" but I would hate to find out that I am "not a real man" after I hit the curb sideways on a new ot me CGT that cost $350-$400K.
4. Point #3 means you are much much less likely to track you CGT vs. a 12C.
The arguement of E-diff or Mechanical diff is typically made by 911 cup drivers. I personally feel most of us don't have enough experience with brake steer. I know I surely don't. Here is a stock, I repeat a STOCK 12C with standard brakes and Pirelli P Zero street tires going around the 'Ring. I think it does alright.![Wink](https://rennlist.com/forums/images/smilies/wink.gif)

There's also absolutely no question as to how fast the McLaren cars can navigate a circuit. I think I was quite clear about that in my review of the car. It's quicker than just about any street car out there. It just doesn't make me fizz when I drive it, which is a bit of a disappointment. The fun for me is only in the kineticism of the car, the way a roller coast entertains. It is #*&^%$% EPICALLY FAST!!! But never gives you that sensitive feeling of control of rotation and throttle steer. I suppose it's the feeling that I really could "hit the curb sideways..." that makes analog cars exciting. Would gambling be truly exciting if you couldn't lose and software made your bets for you?

I appreciate the vote of confidence. "Easy to rotate and correct" perhaps understates the task... but it responds as you would expect, it is predictable, but it's quite touchy, you need to be fast and precise. The analogy would be that it "cuts easily like a scalpel". Just make sure you're careful with that scalpel! Does that clarify the perspective?

There's always the possibility the car you were sampling is in poor repair. It is basically ten years old and most of them are under driven in terms of miles and demands, so they not what they were when factory fresh.
Of course there's the basic premise that the car is designed to convey a gentleman at his leisure or to transport him at flanking speed, so it's a car designed for excellent conditions, not for California's "poverty and potholes" road system.

[QUOTE=jmenczer;10700263]Ritesh - I understand your point and I think it's well made, which I think is why McLaren have built both the 12C and P1 without mechanical LSDs, and both are meant to be driven with the electronics on. For 99% of the population it instills more confidence and allows people to drive their cars faster.

Classic. We had a friend in common once when he was at McLaren. He just picked up one of those 600+hp AMG whatever in Miami. His bottom line: "this car absolutely should not be sold to the general public."
re Ferrari. Funny how he and Clarkson are in line. No mas power.
Which makes me think the JPM going to Indy in 2014 may not be as banzai as the JPM who cleaned up in CART circa 1999.
Rest of JPM on cars:
AW: Did I just hear that you have a Chevy Volt?
JPM:
Yes I do. I love it! For me when I was 25 it was all about those [performance] cars and now I use a Tahoe with a bike rack that I take my bikes everywhere. And if I need to go anywhere [else] I'll take the Volt.
My wife gave me a Nissan GT-R when they came out and I've still got it -- it's got 5,000 miles on it and it's five years old.
AW: See, like you with Porsches, I don't love that car …
JPM:
Oh it's the baddest $#%&*@! car!
AW: But it's almost like a video game, it does everything for you.
JPM:
OK? That's a Formula One car. A Formula One car will do whatever you want, however you want it. You look at an F1, they never fight with the car, F1 it's on rails, the thing is on rails.
At least when I was there, the difference between the really good drivers and the good drivers is, a lot of the places -- and that's why it's so hard for the younger guys -- the limit is not the car, it's you. Especially in the faster corners.
AW: So basically you just have to believe that the car is going to stick to the road?
JPM:
This is a true story. We [the Williams team] were testing with Ralf Schumacher just when I went there right before the first race in Melbourne. We were testing in Jerez and he's braking 30 meters deeper -- we come out of a really fast left-hander in sixth gear and you've gotta brake for a second-gear right. And like, I'm braking -- bang bang bang [on the downshifts] -- and turning. And he's braking 30 meters later than me. It's like, how the hell are you braking 30 meters later and actually making the corner?
AW: Thirty meters, that's about 100 feet …
JPM:
That's 100 #%$^&*! feet, yes!
AW: And a world-class road car, like a C7 or ZR1 or Ferrari or Porsche -- granted, it's still a road car on street tires, but still -- usually needs 100 feet or more to stop from just 60 mph!
JPM:
Exactly. That much distance he was braking deeper than me. And I got that distance down to like half and then they put on new tires, and I tried to go deeper, and I ended up in the tire barrier.
And then a year later, because you understood the car and learned the car, I could actually go deeper than him everywhere and faster than him in all the fast corners. 'Cause the faster corners, the problem with having so much grip, think about the middle of the corner: Let's say you can go through the middle of the corner at 150 mph. But it's how do you get [down] to the 150 mph? Do you lift early and get to it or do you come all the way here, brake all the way in and hope it sticks? And that's where F1 was unbelievable. You could go so far.
Silverstone, the first corner? It was wide open. When we went from the V10s to the V8s, it was -- the minimum speed through the corner was 305 kph. And it was seventh-gear, floored. And then you come out of there into Becketts, the left-right? The first one was wide open. I mean, the first time you do it? One of the harder things with racing like that is, as you're not used to it, you stress yourself [physically]. The first time you go to do it wide open, you try to hang on [to the wheel] harder and you actually turn in faster and screw it up. If you know it's wide open, you just go [make tiny little smooth steering inputs] and take it wide open.
re Ferrari. Funny how he and Clarkson are in line. No mas power.

Somewhat germane to this thread - Montoya interviewed by Autoweek...
JPM: I was a big fan of Ferraris so I had a 355, then the 360 coupe, 360 Spider, 430 Spider. But by the time we got to the 430 I said, there's two things that are gonna happen with this: Either I'm gonna kill myself or I'm gonna end up in jail.
I put 200 miles on it and I said you know what, to enjoy it -- for me, if you're not pushing the car, if you have a Ferrari and you go through a ramp exit, that thing, you better be drifting! And when you do that in a Ferrari, you aren't doing 80, you're doing 130 mph. And at 130 mph if something goes wrong … yeah.
