That could be a factor, but it's also lighter. And .2 GT3 that it roughly matched runs tires that are much closer in size - 245 and 305 (although that was on different days so may not be comparable)

Your feel for what the limit is, is probably much different than the actual limit. This is what makes it nice to compare lap times from one driver who can take a car closer to the actual limit, like Randy Pobst. So while one car may feel buttoned down and composed and you push it harder; another feels like it’s moving all over the place so you imagine you are at the limit and under drive it. This is what I think you experienced.

When I took a fast lap with the instructor at PEC Leipzig it really opened my eyes to just how hard you could push a GT3 and how I was fooled into thinking I was anywhere near the limit. And not to brag but I do OK racing.

And to be tedious like Waxer, just think what the GT3 would do with R cups, worth at least .5 a second or more per lap.

There is an non-RS GT3 on Sport Cup 2 tiers in that same table. Also, in terms of performance, I'd say MPSC2 < Corsa 4< Trofeo R < MPSC2 R (although I did not try the last one in this list) Both Corsa 4 and Trofeo R are faster than MPSC2 on the same car.

What I'm saying that results are not explained by tires at all, and are very surprising. Maybe McLaren was on old tires or not set up right. It should have been at least faster than the non-RS GT3. Even 570S is a very fast car.

Remember that a true comparison is when the test is done on the same day, same conditions, by the same driver.

As I mentioned above in my PS, I was surprised by the result. However, Randy is as consistent as a driver can be, especially on a track he knows so well. May be the Mclaren was malfunctioning?

991 GT2 / 3RS lap times are a testament to how good the 911 chassis is and what it is capable of. Fun factor aside, 997 was good, but this 911 chassis is at another level. Lets see what 992 will bring.

Hard to say. I was so impressed with the 600 on the track vs my rs I went and bought one. I was much faster in the 600 of which I was unfamiliar with than I was in my rs. The car just checks all the boxes. To me the 600 is at a much different level than the rs

2" wider front track will be an advantage right out of the box. It'll be interesting to see how much of the 8-speed PDK weight gain they can undo. No doubt it'll be faster.

I was...thank you didn’t realize it was on R’s....thanks!

the video showed a wet track . Gt3rs was on cup 2 tires and did a 1:38. They didn’t even show the lap time for the 600lt. At the beginning of the video they said that it was on p zeros .

did I miss something ?

gago1101

Yes you did. Did you watch the full episode on Motortrend on demand?

Don’t disagree, it’s personal. I, for one, am still learning to get most out of a 911. I usually feel more confident in front or mid engine cars. I was as fast in my late f80 m3 at Sonoma as I was with my late .1 gt3. Didn’t mean m3 was better. I just need to learn to drive 911 at its limit.

I think the fact that I was able to turn a much better lap time in an unfamiliar car than I could in a car that I had been tracking for a while really hit home to me. I good track car is a personal thing. Its like a comfortable pair of shoes.

The turn in is just razor sharp and I was able to carry much more corner speed. Throttle could be applied much sooner at exit than I ever could in the Porsche. I can only imagine the improvement when I go to a 325 rear tire.

it must be a totally different car then the 570s cause to me my 19 gt3rs is on a much higher level then my Mac!

It seems every review says that same thing. The 600 is vastly different from the 570. I drove a 570 and just wasnt feeling it. Drove the 720 and while being very fast it felt soft. Great on the road but not what i was looking for.

My dedicated track car is a radical and i am fortunate to use it about 40 times a year. It seems since buying it i just dont feel the excitement in a street car on the track until i drove the 600.

This exactly. RS was on Rs and the 600 LT was on Trofeo Rs which are comparable tires and a whisker apart. Mac had a bigger advantage in weight, hp and tq that should have more than compensated for the infinitesimal tire performance difference. Mac also is $50k more on average in price.

RS imho wins on numerous levels. Kind of explains why the RS was one of the very few Top Gear rated 10/10.
