I'm in the market for an '06 Coupe with automatic trans and I am considering whether or not to get the Z51 performance package. I don't plan to race or do autocross (could change) and I don't want to have a harsh ride for my everyday driving. Can someone tell me what this package does to everyday handling? How does this affect the Active Handling feature and how much does it affect mileage? Any advice you can give me will be helpful. I am also checking out some of the dealers who sell through the internet and wonder if anyone has had any especially good or bad experiences buying their Corvette this way. Any problems with interstate shipping of the car or in getting the local Chevy dealer to do the dealer prep on a car they did not sell?

Since you will be getting the new 6sp I'm guessing the Z51 could be a reasonable track package. The 4 sp on track is not a good combination, although I've seen many do it. Requires several adjustments to not get caught in a hard downshift while still in corner. I've had a ride in a Z51 std 6sp and it is very like my '02 and wife's '04, not harsh but not a pure cruiser either. Depends on what bothers you when you hit rough roads. I'd sure try to find a used C5 Z51 and give it a drive.
I don't think it changes the road manners of the car at all. On track you are way past road limits and it does help with body roll and spring rebound rates. No effect on the Active Handling that anyone has mentioned.
The mileage of the std 6 sp is greater than the 4sp auto, but should be closer with the new 6sp auto. 6th is not as low in the auto so you are going to give up tenths of a percent for sure, it can't be better. I think the final is like .55 vs .5 which probably won't be measurable.
Going with new 6sp auto and Z51 will be new turf so you are into unchartered territory.
I don't think shipping is any issue, and as far as dealers there are reports that some are better than others, as would be expected. I've also heard that Caddy dealers usually get better marks and some will do this exercise.

"The 4 sp on track is not a good combination, although I've seen many do it. Requires several adjustments to not get caught in a hard downshift while still in corner."
I agree, I did a track day with my A4 and found the shift logic to be annoying. You either had to slow way down so you could complete a manual downshift with the accompanying rearend twitch; due to no rev matching. Or if you leave it in 3rd, you get a big rearend twitch at some point after turn in when the box decides to downshift to 2nd. The harder you push it the more annoying it all becomes. Off the track I never miss a manual though and I have no regrets buying the A4 when I did. After one session every street car I have ever driven starts to suck because it doesn't handle like a race prepared car.

I drove my C6 to Carlisle Corvette show and installed Bassani performance exhaust for $850. I listened to Corsa and Borla but this makes a huge difference in the sound. My 2000 had a nice rumble but the C6 was way too quiet for 400 hp.

Have you heard the new Magna-flow exhaust? I heard it and it sounded really smooth and with a nice burble at idle. Still, my picks are Bassani and Borla. My brother installed the Bassani's on his Z06 and it was ok. But I installed Borla's on mine and it made a world of difference. It may be that the 7.0L motor's exhaust is more toned than the 6.0L, however my pick is Borla.
#607 of 917 Best exhaust system

Which of the aftermarket exhaust systems will make the C6 exhaust a little more muscular but not overwhelm you at normal driving speeds? I'm waiting for my new C6 and it will have satellite radio as well as the Bose sound system, neither of which I want to drown out while driving around or at regular cruising speeds. Not to mention that I don't want to cause further hearing loss to my middle-aged ears.

It's been said that Flowmaster Super 40 muffler's with the Delta-Flow technology are the best for being quiet until you crack open the throttle on the GM small block's. I happen to agree with them. I own everything from a '58 to a '63 Splitwindow to a '67 427 to a '03 Z06 to my latest '06 Z06 and I must say that they have a great sound at normal cruise but at full throttle, they mean business. I put the Borla's on the new Z06 mainly for the low-resriction. But the lower the restriction, the higher the resonances. I can live with it. Other's can't. Go to a good muffler shop and check'em out. Another good idea is to drive stock just to see how long you can live with it. My brother and I agree that Chevy has really watered down the tone between the C4 and C5 and then the C5 and C6. Maybe it's with all the new emission regs that gets put on manufacturers each model phase. IMO, it has to have rumble to be considered a legit Vette. Ahh, the good old days of the L-88's and the old 427's were great. May be why I'm so deaf now.(lol)
Oh, and enjoy your new toy.
#609 of 917 There was an article on the Magnaflow in Vette Mag
Nov 28, 2005 (9:42 pm)
It was for the C5 and caused me to get the Magnaflow with X-pipe. It is actually quieter and deeper at idle but louder past 3k rpm which is beyond cruise speed. The wife has Corsa Indy on hers and it is much louder at idle but not really any issue between 1500 and 2500 rpm so ok at cruise, again above 3k it is loud, much louder.
I think if I had to do it I would wait some for articles to get some real facts with test gear. Flowmaster on my daughters '00 Mustang GT was too loud at cruise, for me.
When you change exhaust on the new Z06 does that eliminate the bypass valves at 3500 rpm? Seems like a nice feature but I have yet to hear it.

Yep, it eliminated mine. It sounds much nicer with the low-restriction. And it still passes the sniff test in all 50 states, because it is cat-back. I didn't want to get into all of that super-hollow catalyics because I love my warranty. I am however going to have the new polished Edelbrock headers put on this weekend
At cruise, it's much like a stock Z06, maybe a little louder. But at full tilt, it's like the old 427's of the old days. I prefer it that way.

I have come across a 05 convertible with damage on the drivers side. The damage is on the bumper, fender and door which all will have to be replaced. The seller is asking 41k for the car which has 9600 miles on it. The car is driveable and when I drove it there was no pull to the left or right. I own a 91 vette and boy is there a difference in power. I haven`t had a auto body person to look at the car yet but what do you guys think?
