    C&D C6 Z06 vs Viper

    I haven't seen this posted elsewhere, my apologies if I missed it.

    C&D was blown away by the Z06 motor, less than impressed with the handling:

    "Sure, the Viper's 1:27.50 lap time was 1.50 seconds slower than the Vette's, but given the choice between the two of them on the track, all of us preferred the Viper. We scored the Viper's handling a 10 out of 10 and gave the Z06 a 6."

    "We're still buzzing over the Z06's ferocious 3.4-second burst to 60 mph. "

    "If the Z06 encountered any kind of bump or lump in the pavement as it was exiting a corner, the result was a nearly instantaneous outward snap of the tail. It was so sensitive to bumps that the Vette uncovered lumps in the pavement we never knew were there-even though we've done hundreds of laps at Grattan in stiffly sprung race cars."

    "So if you're eager to take a Z06 to a race course, you might want to consider modifying the suspension or trying different tires because our sense is there was too much consideration paid to a cushy ride and perhaps that's why it's such a handful."

    Re: C&D C6 Z06 vs Viper

    Those Corvette runflat tires ride like tractor tires. It crys for Michelins.

    I would really go to a alignment shop before tracking any new car. Most new cars are out of spec. Fortunately Vettes have lots of camber/caster adjustment. The last Z06 included a video tape with the owners manual that showed you how to set up the suspension for track use. Already the suspension, chip and header companies are coming out with lots of stuff for it.

    Here is a track review of the Z06 by Lou Giglioti, who races Corvettes and also has a tuning business. http://www.lgmotorsports.com/

    "Hi guys,

    "I took the Z06 to the race track, Motorsports Ranch today for the first time. Here are my observations:

    First, the car had stock air filter, LG Headers, 484rwhp, stock cam (waiting for the big one and tuning) and Stock, as delivered, tires and stock as delivered alignment.

    The car is extremely fast but I will replace the shocks this week. the car (at speed) and at the limit floats too much. The shocks are not doing a good job of stabilizing the car so the suspension can do it's job.

    Water temp, after about 4 or 5 laps, was up to 239 degrees, and the oil temp was 269 degrees. This is on the high side for me and I had to slow down or stop for a couple of laps each time to cool it down.

    We will install one of our radiators next week if there are no unforeseen changes that were made to this car's radiator.

    The brakes worked perfectly. But they better since we upgraded the front brakes to a StopTech 6 piston with a stoptech aluminum hat and used a good compound pad. This brake package with rotors made the brakes so good they were not even a factor. They worked each time and every time as if they were new, and being hit for the first time. We changed these to eliminate any chance of hurting the stock calipers like other reports that have come to light. Good choice in my opinion.

    Handling was not too bad, considering that we didn't put any track alignment on the car. The car needs some neg camber and a race alignment if one were to flog the car like we did today.

    It was the fastest street car that i have ever driven at MSR. We turned many laps in the 1:22 range with our fastest lap at a 1:22.333 on stock tires. We tried some Toyo tires but the traffic was so bad that we got balked every hot lap attempt. with some good tires, I can see a 1:20 or a high 1:19 in the car.

    By the end of the day, one of the lower camber bolts had moved and killed the alignment even more. We have some locators that we will install to hold the A arms in place before the next time the car is taken out. We made them for the C6 and looks like we will need them on the Z06 also.

    We ran down every car out there including a Ferrari F40 with a good driver in it and a bunch of Porsche cars from RUF Porsche.
    There was one BMW, race prepped car with slicks that was keeping up and in fact in the really tight sections, it could close up on us. The little cars really do the tight parts better than our Z06s can. He said that on good days and good tires he can run in the 1:21s. He was good enough to loan us his timing beacon so we could get the lap times recorded.

    All in all, I would say that it is a very track worthy car that needs shocks, sway bars, Radiator, and a good cold air intake. I am very sure that the stock brakes would have been an issue, so I am glad that we went with the Stoptech 14" brake upgrade.

    I am probably more demanding of a car than most but we do plan on upgrading all of these components until we have a very drivable package that will be totally user friendly. At slower lap times the car would be more than adequate."

    Re: C&D C6 Z06 vs Viper

    So it needs shocks, sway bars, radiator, cold air intake, and aftermarket brakes. And I thought it was track ready. Silly me.

    Re: C&D C6 Z06 vs Viper

    Apparently so for him, he is a professional racer and competes nationally. As delivered its ok for casual track use he said.
    But whatever,,, Corvette speed parts are ridiculously inexpensive compared to Porsche, Ferrari or Bimmer parts, and the cars win in their class, so that ought to tell you something.

    Let's see how many laps a stock F430 would last around a track with Schuey in the hot seat . There is no such thing as a track ready car ( i.e., real lapping fender to fender in 10/10ths anger in a real race ,not one timed lap for a mag comparo ) that can be bought off a new car showroom, whether Porsche GT3RS, Ferrari CS , Vette Z06, etc. LG's review as a racer is from that point of view.

    Re: C&D C6 Z06 vs Viper

    Bit troubling from a bumpy mtn road driving feel perspective if a US car rag (w/all that GM ad rev to risk)grumbles re: Vette's feel on a track w/presumably smoother pavement than public roads....

    The GT2, GT3/RS IMO ARE track ready, with the exception of alignment.

    Never mind a race course, does this car sound fit for daily driver duties?

    On a mountain road, what do you pick: 997tt or Z06?

    Re: C&D C6 Z06 vs Viper

    with crash on this one, a GT3RS is basically ready to rock!

    Re: C&D C6 Z06 vs Viper

    PS- mountain road for SURE 997 turbo, no question bc ur on a mountain, and i want a car that wont throw me off! AWD baby!

    Yeah right - show up at a racetrack with a GT2 or GT3RS staightght off the showroof floor with factory brake pads , factory shock/spring calibrations ,factory brake fluid, factory cooling and tell some dedicated 2300 lb track car 911 guys that you are ready to go fender to fender with them for 50 laps ....

    Re: C&D C6 Z06 vs Viper

    I believe there is a difference between track worthy and race ready. There are several track worthy road cars on the market that don't do too bad on the track for open driving events where you wouldn't driving much longer than 30 minutes at a time.

    Yes, then can be made more track oriented by making modificaitons to the suspension/brake system and by adding safety equipment. But many of these owners just want to turn a few laps and then drive home in their road car. It's a compromise. It's more casual and not the most extreme track driving. I consider mods like brake pads and fluid very minor modifications.

    I agree that pure track or race cars are in an entirely different league. There's also room to modify a track worth road car like the GT3 RS before it becomes totally unusable in the real world.

    Depends where in the spectrum you want your car. But for the casual track driver, you can away with a GT3 Clubsport and relatively few mods.

    I'm willing to give it a shot

    Re: C&D C6 Z06 vs Viper

    Haven't had the 430 to the track yet, but my 360 could handle 30 min sessions balls out with just competition brake pads and fluid. The springs, shocks, and sway bars were spot on.
