Having owned both, the 600lt is much better in my eyes. I just love the feel of the steering and then the exotic feel. I changed my exhaust which I felt was the only drawback

The AMG 4.0TT may not be as impressive in some respects, but it does sound pretty damn good (better than McLaren, imo). And sometime soon it will be paired with Aston-Martin's 7spd Manual Dog-Leg box...

To me there is no comparison. To each his own. A Porsche is a Porsche and an RS is an RS.
600LT is very nice and I like the car a lot but no way would I give up my 3RS for one.
More proof that the RS punches way above its weight.

Lets stop finding excuses why the LT was slower. Mac put the tires on the 600LT it felt were best. They were clearly gunning for the 3RS. I sure they considered tire choices and made their pick. This is stock vs. stock off the showroom and in fact my bet is the boys from Mac cooked the books some Ferrari style. They didn't come across the pond just to spectate.

The 3RS is the better car imho in many many ways one of which is performance for the dollar.

Nuff said.

Variety is the spice of life. I drove the 600 and decided it was time to get rid of the rs. I have had porsches for the last 15 years but I have to say the 600 is at another level at least for me. Can really feel it on the track. I have changed the exhaust and gone to a 325 in the rear which really made even more difference

Totally right - my memory is failing me in my old age. That's significantly narrower.

I've tried a 12C, a 570s spider, and a 720s spider, but while they're nice cars and really fast, they didn't really put a smile on my face. Last time I had a similar feeling was when I test drove a Huracan. I bought it anyway, thinking it had gotten so many good reviews so I probably just needed to get used to it, but after a year it was still boring to drive so I sold it.

Lesson learned, unless that first impression is "I absolutely need this car", I'm going to pass.

I would imagine I would like the 600LT better since it's more hardcore and less of a road car, so I'll reserve judgment on that one until I try one.

I would have expected that with a 570S but isn't the 600 lt supposed to be the track special version? With that engine and turbos should have smoked the rs.

Problem with mclaren is too many models and too many iterations and segmentations of the same basic engine. They tune it differently with software and come up with too many model variants too quickly. They also artificially hold back some of their lower range models with suboptimal tires sizing.

Gets boring after a while and kills resale value for their customers.

I think the size and shape of the carbon tub is the limiting factor on wheel/tire width

What if I told you... engine behind the rear axle is the secret sauce (I didn't, but what if I did?)

McLarens are undertired up front due to the architecture of the car. They cannot fix it without a major re-architecture of the car.

Since Macs are mid-engined with the fuel tank located behind the driver, the driver sits very far forward. The driver's feet and the front wall of the carbon tub limit space for the all the components up front - suspension, hydraulic accumulators, smallish trunk, and tires. This affects all McLarens including the P1 and Senna.

The rear-engined 911 does not have that issue as the driver sits further back and his feet do not compete for space with mechanical components up front.
Even the mid-engined Cayman does not have the issue because it locates the driver more in the middle of the car with the fuel tank ahead of the driver instead of behind the driver like in McLarens.

A nice result of McLaren's architecture is that because your feet are very close to the steering axis, it steers like a go-kart with your feet changing direction first. That is cool!

Come on tell us what the secret sauce is. Not nice.

To summarize;

Easier to drive, confidence inspiring and fun.

One can mercilessly beat the living daylights out of any GT Porsche car, allowing us to make up for the lack of talent with massive amounts of track driving experience without the thing breaking.

Even with pro talent RS is faster with less power because it corners and stops better.

It is amazing how the 991 platform has just dominated lap times across the various iterations and trims since its debut while hanging on to the traditional rear engined layout which everyone always thinks of as sub optimal. It almost as if someone at Porsche knows what they are doing.
