That is a pretty dumb thing to say. There are courses that will favor one and some the other. Since we are talking laguna, motortrend's test around the course had the viper at about a half second faster with the same pro driver but different day. Hardly a decisive victory. If the upgrades to the acr for 2010 really helped its lap time then the zr1 needs to be retested too because for 2010 it now has PTM.

Fit ZR1 with MPSC and see how it improves lap times.....
Maybe a Z06 has track record on Nurburgring next year
August 3rd. there will be an attempt to retake the record from ACR, 7.22
There is also a heavily modified BMW M3 that has done 7.22, it is called Loaded

While I agree the ACR is faster around Laguna Seca, with it's R compound tires and aero package, than a ZR1. In reality it is a lot closer than 2 seconds. To have true comparison you would of had to have a ZR1 at the track with the ACR with the same driver doing an equal amount of laps. I would guess that it would be about .5 sec behind per lap.

fact of the matter is the viper is faster than the zr1 on a road course. because of tires? more than likely YES but.........thats the way the viper comes from the factory. the zr1 got the shaft on that one. should better tires be an oiption? sure. will it? no. the zr1 is faster in a 1/4 and the viper is faster on the track. thats just the way it is.......for now

Perfect post, athough the ACR is geared more for the track, it is a street car, just like a corvette, what people dont know is that there is all all purpose race viper called the competition coupe, that dodge has sold for years. BTW I own both Viper and 06 Z, brand loyal people are always going to make excuses, tires, illegal splitter , bla bla bla
, most of the people who argue are the ones who Zaino their cars every week , and complain about wanting a automatic hatch closer , they read magazines and havent been near a racetrack.fact of the matter is the ZR1 will never beat an ACR Viper around a course, period, get over it already

Now see a ZR1 can put on a set of PSCs and still be street legal but the ACR can't drive around with it's front splitter installed and be street legal. (This one always gets the Viper guys fired up
)We get the point though the ACR from the factory is a little better track car. The ZR1 from the factory is the better street car. The ZR1 can be made into a better track car with tires and minor suspensions adjustments. It would be much harder to make the ACR into a better street car. It all depends what you are looking for.

I don't have a horse in this race, so I could care less, but we all know the tires really do make that much of a diff. I would love an ACR and possibly even get one over a ZR1, but to openly admit a ZR1 with sticky tires will not hang door to door is insane!

It is great that the offer them OEM, but really how many people that are serious into tracking their car stick with the OEM tire? Tires and brake pads are the first to change for any serious open tracker. Now, I don't think anyone will be changing pads on a ZR1.
Now see a ZR1 can put on a set of PSCs and still be street legal but the ACR can't drive around with it's front splitter installed and be street legal. (This one always gets the Viper guys fired up)

What you need to understand ,is that Viper owners dont want a better street car, we want all out performance. I have owner 5 corvettes and currently own a C6Z, you cannot truely give a realistic opinion until you have both. They are very different cars, even power delivery feels nothing alike, when both car put out great numbers.
By the way the power delivery of the ZR1 is different from the Z06 too.

Problem with these arguments is this - To hang with the ACR around a road course, street legal R-compound tires and track alignment 'ain't gonna do it'. Those that have driven both know this.... And GM knows this, or they would simply offer an R-compound tires as an option and shoot for those records. Now if you slap a full aero package, coil-overs, track alignment, and some tires then it would be interesting. But what's the point? If track days are your thing, the ACR stomps the ZR1. If daily driving + comfort (or frequent trips to the market) + 'combining darn good performance' are your thing, the ZR1 stomps the ACR. Simple. To have either 'match' the other in its strengths would take a lot of work and money IMHO.
BTW - There is a HUGE difference between a 'street legal' 80 compound tire and an all out racing slick. HUGE. Which is why I laugh when people keep referring to the ACR's tires in this manner. Sure, on a road course 80 compound is obviously a bit better than ZR1/Non-ACR Vipers 220 compound. But the difference is not monumental like comparing street tires to full out racing slicks.

And how does that equate to changing tires (a consumable) and doing an alignment?
