c5 vs. z28 of course i know the c5 would beat it in a drag race, but stock vs. stock is there that much difference in performance between these cars. and i'm talking up to about 110mph or so; i know a vette will kill it in high speeds.

No there's not much of a difference. The Z28 with it's live rear axle is alot easier to launch than the IRS Vette. If a LS1 F-bod gets a good launch and gets a lead on a C5 Vette it can hold it for awhile imo. They seem to run similar times in the 1/4 so it's definitely a driver's race on low end.
Also of course the F-Bod's were underrated so they put as much power to the wheels as the average C5 Vette. Since the Vette is much lighter and more aerodynamic it can overcome the F-Bods having as much power.

They make the same power, and the Vette's IRS eats more power than the live axle F-body, thus reducing the weight advantage of the C5.

My opinion is the C5 is not really much faster at highspeed than an f-body stock vs. stock The most C5 can go between 175 and 180 for M6 and 180-185 for A4. My best was 175 too

Well, my 2000 WS6 auto with 3.23 gears went 13.46 @ 103 stock and my 2004 C5 auto with 2.73 gears went 12.92 @ 107 stock with pretty much the same 60 ft. If I had the optioned 3.15 gears I beileve I could have hit a low 12.8 stock. I have 2 friends with 6 speed C5s and they went 12.6 stock. I know some 6 speed F-bods have been known to hit 12.9-13.0 stock. Stock vs. stock I think the C5 will come out on top.

I reserched this before I got my Z28 as I wanted a LS1 because of how well they react to performance upgrades and after checking it all out I couldn't justify paying double for a car with the same engine.
I am building a street/strip 10sec car so a vette wasnt needed but if I could get the cash togther I would buy a C6 ZO6.

On average the Vette will be a bit quicker, but not by much and usually it'll be decided by traction or the better driver.

Now take a lighter weight '01-'02 Z28 vs the '01-'04 Vette, or a '98-'00 Z28 vs '98-'00 vette with the same trans type and the gap will be smaller.

I was just saying that you have to look at '97-'00 C5 vs '98-'00 F-body and '01-'04 C5 vs '01-'02 F-body, IMO. Just try to compare model year to equal model year whenever possibile since changes have been made to the LS1 over the years that gives the newer C5s and F-bodies some advantages over the older models.

I had a 2004 M6 C5 and a 2002 A4 Z28 at the same time.
I used to let my buddies drive one or the other and we would race all the time.
The best stock time I got out of the C5 was a 12.89@110. The best time I got out of the 2002 Z was 13.06@106. It was a strong running 2.73 car with just a lid, filter and muffler..
In a race, the cars would pull even until about 70, and then the C5 would start to pull on it, putting a couple of lengths on it in the 1/4. The faster you went, the worse it got for the Z28. By 150 it was a wipeout.
