Z06,...Putting the HP to the ground

Is it not more a question of torque than hp (speculating that your Z has more torque than your Italians)?

 

That's interesting. How do the torque curves compare? Do the Italians make their peak torque much higher in the RPM band than the Z?

 

Combination of torque, gearing, inertia and weight distribution IMO.

 

Maybe the Z06 was never intended to go forward?

 

Notice those big 12's sitting right above the rear tires? Put some scales under the rear tires of all three. I think you'd be suprised at what you'll find.

The OEM C5 ZO6 tires were kinda crappy Good Year Supercars. Toss on some better rubber, or some drag radials and you will be much better off. One of my cars puts almost 400 to the wheels and with warm drag radials I can dead hook.

 

One of my bud's has a new Vette and we both were amazed how easy it lit 'em up all the time . .. he just replaced the tires and it's night and day with the same type he rolled off the floor with . . . he was on a waiting list so this car did not sit on the showroom floor FWIW ... he's not a hardcore driver but he's convinced the factory tires were a different compound 'cause it lit 'em up like crazy from day one . . now it hooks up and is scarey almost


cheers

 

Tire compounds can make a huge difference no question.

While I don't know the F/R weight ratio of the ZO6, I do know that a balanced F/R ratio has more to do with overall handeling than 0-60 times.

If you just want to do 0-60 times you want more weight on the rear (driving tires) with gobs of tourqe.

All you need to do is look at the evolution of Dragsters. Sepcifically top fuel/rails. Once the engine got behind the driver and more wieght was put (transfered) on the rear tires the times and speeds went off the charts.

Even pro-stock and funny cars are practially mid engine cars.

 

+1 radials are the way to go if you dont mind driving them in rain. If not Look at some PS2's.

 

I think it has something to do w aerodynamics as well

My C6 Z is very slippery but doesnt make a lot of downforce, something I will be addressing w a new rear valence, new GTR hood & a carbon fiber front splitter

I think its just a Vette thing as my C3, C4, & C6 can all break traction and fishtail very easily

The F40 can also do this though


btw although the Diablo has more torque than the C5Z it also probably weighs more

 

No, unless the tires are really low, new tires wont address that issue

if it really bothers you and you want to keep the car I would suggest some adjustble race shocks that would let you fine tune the suspension

 

I wouldn't have believed it unless I experienced in my buddy's Vette . . same tire as factory and way more hook up . .. we theorized Chevy didn't want guys busting the tranny as they pulled off the lot so maybe had some special tires with extra mold release .

Do not add weight .. unless it's downforce!!!

 

Are they run-flat tires? We have both a 1995 ZR-1 and a 2004 Z06. The ZR-1 will spin the rear wheels much more readily than the Z06...I put Micheline Pilot Sports on the ZR-1 at about 20,000 miles and that seems to have improved it a lot.

 

The c5 Z06 came from the factory with run flats. They are not the best tires out there for sure. A switch to Mich pilot sports will improve the traction and overall performance a great bit.

The C5 Z did not come from the factory with run craps... It has Goodyear Supercar's and instead of run flats it came with a small compressor and a can of "fix a flat" in the back of the trunk in a small plastic case...

The problem is that as the Goodyears wear down they get harder and after about 3/4 of the tire is worn they are really bad. Note too that they don't like it cool and are even worse if god forbid it is wet....

Get a new set of stickier tires and you will be fine.... Just realize that the C5Z has about as much power as the rear tires can handle. With new stock tires, if you are on it hard near the top of second gear it will break the rear tires loose even if you are pointed straight ahead, so there isn't any margin for tire degredation over time...

 

False, get some good meats on there. Like I said before. If you want a overall tire get PS2's, if you more into drag racing get some drag radials from Nitto, BFG, or Mickey Thompson.

 

My cousin had the exact same thing on his C5Z and so did I with my modified C3. New tires was a night and day difference. I don't remember what he bought but I got General UXPs for mine that I like.
