Default Non Z51 Performance Statistics

I am going to get a C6 Corvette and am currently leaning towards the base suspension with a manual transmission. I don't plan on racing the car and I want it to be confortable for long weekend drives, which is why I am leaning towards the base suspension.

All the published performance statistics I see are for the Z51 with a manual transmission.

I am wondering what kind of performance hit one takes by choosing the
base suspension which has the taller gearing and harder tires.

I don't want to be getting out run by some kid in a new Mustang GT.

If anybody knows where I can find the 0 - 60 and quarter mile times for
a non Z51 stock C6 I would appreciate it

Thanks

the gearing in the Z51 allows it to get shy of 2/10s quicker on the 0-60. this is per most rag reviews i have read.

the tires may have the supercar compound, but if you're not tracking it, you're not gonna need it.

as for some kid in a mustang GT walking your magnetic ride C6...not gonna happen. not even close, come on now.

There has not been a road test that I have seen of a six speed non-Z51 car. But GM posted stats, and it was only 1/10's slower in the quarter mile. I had a Z51 six speed coupe, and now have a F55 six speed vert.

It's a little hard to make a direct comparison, because I got the current car when the weather was really getting hot. But I did have a chance to compare my car to a Z51 car recently, and I was very pleasantly surprised (we cannot post "racing" stories on this forum, so I won't).

Dont worry too much about the straight line performance on the base model since you are getting the 6sp. anyways. The Z51 true benifits is with the suspension. Its true that ALL car magazines only test the Z51 and thats a bummer for those of you who wants to know the performance of the base model.
Now I wouldn't worry getting out run by a Mustang GT, Its the SVT Cobra that I'm worried about.

Then I would lean more towards the Z51. With the performance gear ratios, etc available in that package, its a bargain.

not allowed to discuss road racing here, but i will summarize by saying that the magnetic ride absolutely smokes the new mustang GTs. with the Z51, you will embarrass them by one more 1/10 of a second. worth $5000?

Not sure I know where the $5K figure is coming from. Please explain.

that's a rough estimate of how much it costs at the dealer. there was another LMB exactly like mine, except that it had the Z51 and it stickered for $5k more than the magnetic ride i bought. *shrug* dealers...

If you price it out on the Chevy site aren't both options the same price? $1695.00 for the Magnetic Select Ride and $1695.00 for the Z51? (Actually on my sticker it says $1495.00 for the Z51 package. There must have been a price increase as mine was built in October of '04)

I had no idea that people were paying an additional 5K for the Z51.

I had a C6 6 speed I got in October 04. Just got it bought back from GM since the Clutch SUCKED. Replaced 3 of them for the TSB. Also lost the crank pulley. It had the Mag ride. Just picked up my Velocity Yellow Z51 auto. The Z51 is way nicer and feels quicker. It is not as stiff as you think. I had the dealer tell me that in October and I got the Mag ride. I was sorry I did that after finally test driving one. Z51 all the way.

Get auto with F55 and the 3.15 rear axle. If you want to put on Z51 sway bars - that might be good. In auto, the close ratio MN6/TREMEC is not an option.

I wouldn't worry too much about straight line performance. The Z51 gearing makes for a helluva takeoff in first gear, but you have to shift sooner too. When you break it down, the .1 second difference is about right. One option to you is to get the base suspension and add the Z51 sway bars for less than $150. You'll then have 98% of the performance of the Z51 car for a lot less. That's what I did. My fastest time with the base 6 speed at the dragstrip has been 12.8 @ 113.5 MPH and at about 1200 miles, the engine wasn't even completely broken in when I did that.

And... take your base car with the Z51 sway bars and get rid of the run-flat tires and put on some real tires, and the base car will outhandle a Z51 with run-flats. The run-flat tires are the biggest performance detriment that these cars have.

Wow, though still so very slight I'm surprised those two set ups would run any different at all seeing that there is no real 'straight line' performance advantage of a Z51 auto over a performance axle ratio base car...if anything the Z51 car should be ever so slightly slower because it weighs slightly more and has a stiffer suspension (less squat on launch), maybe it's the tire difference.

If I did it again, I would go Z51....but a base or F55 with 3.90's and Z51 sways I think would be a great compromise

even if the z51 is .1 quicker,you wouldnt be able to tell much of any difference on a tenth.Only .2 and higher will you feel an actual decent seat of the pants.Save the money for that package and get yourself a tune and headers and you will be the one pulling on the z51.If anyone says they noticed a big difference in performance of the 2 ,they are full of it.
