[ZR1] Lightning Lap No 4 at VIR

I hear what you're saying, and agree...
BTW - Call me crazy, but I feel the C5 Z06 'may' be the best track Corvette ever produced. Why? Because it can easily & greatly be improved upon from OE. Equal tires, a bit of suspension work, and a few minor engine tweaks and I'd put it against a ZR1 on a road course. I bet if it was behind, it wouldn't be by much. I've seen plenty run hard at tracks, and they are monsters on the road course. If I ever purchase another Vette, this is at the top of the list.
P.S. - Is there any way to improve the steering feel/feedback? I'm sure better tires help, but I'm talking a different steering rack. Heck, even a manual one... Do any racers change this aspect of the car? I love to feel what the car is doing thru my hands, even if I have to sacrifice steering ease (at low speeds or stop)...

It's got the lowest overall weight of the modern era vette's, the lowest unsprung weight (tires/wheels/brakes - stock anyway), and with the plastic fixed roof and small rear glass, likely has the lowest CG, even compared to the alum frame C6Z06.
It needs some help in some areas for serious tracking, but it's a solid platform to build from.
Steering feel = it's taken me awhile to get used to it, and I still don't love it, but it is what it is. A smaller dia wheel helps. DRM makes alum bushings that go between the rack and cradle, I've heard these help for the track, not sure how much NVH they'd carry over for the street.
As for vs the ZR1, it would be a track by track basis. A track like VIR where you can air it out for a couple of the long straights, it's hard to argue with 640 hp. On a smaller regional track where the % of lap spent at WOT is much smaller, things get closer.
I think if you put both the ZR1 and C6Z06 on the same tire compounds, I think folks would be surprised at how close the C6Z06 could run to the ZR1, and possibly even quicker at certain tracks.
What's hard to beat is the potential speed of the ZR1 vs it's everyday livability. A car that's that streetable that goes that fast is pretty amazing.

Melting Slicks
Well, at Spring Mountian all the Vettes (base, Z06, and ZR1) at the drving school are on Michelin PS2 tires. The ZR1 retains it's stock ZP tires but the other get a tire change since Michelin is a school sponsor. According to the instructors the ZR1 still 2-3 sec a lap faster than the Z06 on their 2.2 mile track.

Drifting
For example Automobile took the ACR to Spring Mountain for a test vs the GT2 back in '08. The ACR turned a lap time of 1:45.4 sec. I was just out a Spring Mountain a few weeks ago for the ZR1 drivers school. The lap record for a stock ZR1 on that track is 1:40.x by one of the school instructors (JJ, for thoes who have been there). He is even faster than Ron Fellows (who's name is on the school) by a few tenths. So is the ZR1 really ~5 sec faster on that track than the ACR? No, they are not really comparable times due to the different drivers and days.
But bear in mind that he also has probaby 10,000+ laps at that track, and could drive it without looking out the windshield (which he does while instructing because he's looking at the cars behind him in the rear view mirror during the lead/follows and doesn't miss a thing). Sending a driver in an ACR for a one day test and having him turn a 1:45 is pretty damn impressive, actually. And the post above is dead on--there's no way to compare the two drivers. By the way, JJ also turned a 1:43 in a Z06, and a 1:47 in a Z51 C6, all track records.

The ZR1 was faster than the Clubsport on Cups in this Car and Driver test. Lots of variables though and I would not be suprised if the results reversed under different circumstances. Still, the ZR1 is definitely a beast.

Its very difficult to compare different models to each other on a road circuit.
The ZR1 has a close-ratio 6speed compared the the C6Z as well.
In terms of the C5Z, an excellent platform, but a F360 consistently ran at the top of the pack in SCCA T1 and won one year.

C5Z is still one of the best track cars. I see a ton here at Barbers Motorsports Park on the track days. And with equal tires, I do believe that the tests would show that the ZR1 would be 2-3 seconds faster than the Z06. Too much of a power advantage on the straights.

THE ZR-1 IS CRAZY FAST, THEY SAID THAT THE MURCIELAGO IS MORE STABLE AND IS MORE PLANTED THAN THE Z BUT THE Z GOES AROUND THE CLIMBING ESSES AT 109-110 MPH WERE THE LAMBO IS DOING ABOUT 100 MPH IN THIS SECTION..
