View Full Version : Educate me on Vettes

I'm sure it's been posted somewhere but I'm too lazy to click the search button. I'm starting to think along the lines of a mid to late 2000's vintage Vette for a track car. I'm not at all unhappy with what I have (DD + track car) but now that I've tasted the forbidden fruit of rear-wheel-drivedness I'm liking it. Vettes, to my lack-of-knowledgeness, would seem to be a cheap date to bring along to the track and have a great combination of lots of power and (maybe) access to a big aftermarket for both replacement and upgrade parts.

Could a couple of somebodies here post a really quick synopsis of pros and cons of 2005 - 20009 Vettes (my price range it seems). Are they easy to repair? Are they quick out of the box, or do they need specific mods. Purpose: Track days and maybe GT racing.... Not a DD, but I want to drive it to/from the track.

Not thinking of making any kind of decision until next year but there are a couple of Vette owners here.....

What is a "late 2000's vintage Vette"? Those sound like contradicting terms.

vintage- the year or place in which corvette, especially corvette of high quality are produced.


so yes, makes sense.

easy to work on

best bang for buck turn key race car out there. literally, turn key and go.

massive aftermarket and support corvetteforum.com

Stock suspension and a good street tire will net 2:25s any day.

would not discount c5z06 over C6, but it could be a matter of taste.

Any C5+ vette is fast out of the box. I have an 01 Z06, on NT05 street tires & Carbotech XP10/8 pads no other mods. I wanted a car I could drive off the showroom floor and onto the track no fuss no muss. Just learning the car at CMP and being very conservative (I'm used to AWD) I was around 2.37 IIRC then Geoff jumped in and his first time behind the wheel was pulling very low 2.30's and the tires still weren't squealing. There is a ton more potential waiting for the right driver. C6's are equally as fast, Z06 adds another 100hp. Check the corvetteforum for pro's/cons on ever gen/variant as some are more suited to track duty than others. FYI - I just had Getty replace the transmission in mine with a nice low mileage unit so its back up for sale to interested parties.

There was an engine change on the base models in your range. 05-08 is the LS2, 09-13 is the LS3. LS3 were ~+30hp and ~+30lb/ft. Also in 08+ there were some refinements to the car in general. As Greg mentioned I wouldn't discount the C5Z06.. They're > than the base C6 IMO.

Oh, and if you are stuck on a C6 try to find one with the Z51 package, it's the "performance" package for the base cars. Brakes, cooling, suspension upgrades, etc..

Yep. I had to do a bunch of upgrades to make my car (a) turn corners and (b) not overheat.

Or Z06.

Z51 package on a C5 might be more in my price range. Z06 in my admittedly small amount of research seems to command top $$. So the Z51 package is pretty consistent in the features that it adds across the different model years?

If you're buying a C5 get the Z06 its a no brainer for not much more money.

Andre

Think you might be mixing up gens?, C5 = 97-04, C6 = 05-13 (the gen you asked about).

general consensus I think is that C5 Z06 is best bang for the buck, alternatively a C6 Z51 is a nice option.

dbg

I'd agree with that - bang for buck, C5 Z06. C6 Z51 is a bit more bang for a bit more buck.

My base C6 required a lot of upgrades to make it track worthy. And given last night I still need an oil cooler and upgraded radiator.

^^ So your rad just puked a little out that driver side near resevoir ? That's a good problem, glad to hear. What temps do you see ? My oil sits at 270-280F and rad never gets hot that it matters. I'm not good enough to cause overheating issues.

dbg

Yeah, that's all it was. Temp gauge was a little over 250. Switched to doing shorter sessions, and kept a close eye on the gauge.

Its a Corvette thang, seems common enough on the forums with tracked cars. My Subaru never went above 240 and run 200 on the highway going to work.

The way I see having owned/driven both C5's and C6's.. In a nutshell C5 Z06 is a more raw car, + on grass roots, - on gadgetry. C6 is more comfortable, nicer in general. Less badass but easier to live with.

About $25 to $30. Maybe another $3 per season for tires/brakes and maintenance like alignments, inspections, oil changes, etc. Not including gas.

I usually start with the HVAC off, then at some point I hit the damned thing with my glove while shifting and end up putting the heat on max...

Stock c5z06 will run 300F oil, its fine.

I have an Engine oil cooler and get 254F to 268F depending on ambient temps.
As for water, it will go to 226 before the high speed fans turns on. I see 220F to 230F water on track.

Are there any references that suggest using the heater cools the car down? Diverting hot coolant from the rad through a little exchanger in the dash for extra cooling just seems asinine. And the fan on high? The car is moving at >100mph, how fast does "hot" air come out of your dash?

If your car has a hot heater core (coolant always goes through it) then it might help a little, but lots of cars shut that line down when it's off. The radiator is where you want the heat going.

in my 67 falcon is absolutely makes a difference. Can literally see the temp gauge stop rising as soon as i gets turned on... and not like i just got to steady state coincidentally... i can turn the heat off and up she goes again.

Does it help when it's overheated too, or just at op temp? Hits a lower steady state as well?

Many VWs (and Audis) have a shutoff valve that literally shuts off a loop of the cooling system, I can't imagine it helping them out. I've heard tell most domestic cars have hot heater cores.

If you are running cooler with the heater on, I suppose that means you have enough coolant flowing, but you've run out of radiator (0 pinch-point)

I just put the heater on full, put it on dash vents only, close the center vents and aim the outer dash vents out the window. Just make sure to have the A/C off. Having the A/C on will sky rocket the coolant temps. Although, I will usually turn on the A/C if not moving, will turn the rad fan on full and cool the motor faster.

Funny enough (well not really) today the vette decides to puke some coolant in the Costco parking lot. Probably didn't take well to idling in the gas line with AC blasting but water/oil temps were just fine.

my vette opinion, cause it matters:

if you have the cash, C6 Z51 seems like a more refined package, and from nose/ear witness just as quick around the track as C5 Z06.


Bill's c5Z06 runs cooler at idle with a/c on.... don't know why, but worked while idling in line at autox.

Just an FYI - my boss's neighbor in Richmond has an 05 Z51 for sale. It only has 25k km's.

He's apparently asking 32k.

I think that is a bit high, but given the mileage, may not be far off.
