Hi guys.
I'm driving Cayman 2009 (265hp) and want some new experience.
The most "anti-cayman" car is a Vette don't want to buy any ordinary ponycar because I love to drive on racetrack (curvy one, not the dragstrip), love lightweight sharp steering cars etc.
With my bravery and skills I don't think i need Z06 C6, it would be too much for me. So C6 M/T it is.
In Russia (Moscow, Russia) nobody tracks vettes (because it's an exotic here, owners just cruise them. I heard that base Vette (non-grandsport, non-z06) has flaws and can't be tracked - oil starvation, engine oil and water overheating.
How serious are this issues? Can the base C6 do 2-3 fast laps during session? (2-3 fast laps, then cooling lap, then fast laps again) Or does it need some tuned lubrication system, big cooler for water and oil, tuned oil pan etc?
I won't use too sticky tires, and my tempo on a track is pretty average, so there won't be lap records etc.

Thanks.

 

The C6 Grand Sport manual has a dry sump oiling system, plus additional features that are very good for tracking the car. The automatic version has a wet sump oiling system.

The GS has external oil cooler, differential and P/S coolers, etc. Plus larger tires than the base, and better brakes.

 

does base C6 suffer from oil starvation if raced on road tyres, not high-grip semi-slicks? is oil pan upgrade required?

 

I'll let others with more knowledge answer this one (I have read some people eventually have had issues with oil starvation on road courses).

 

I think it has to do with what type of road course you're running. Long, sweeping curves are where the concern comes in. If you're running a tight course where you're not a WOT while turning for longer periods of time, a stock oiling system might be OK.

More capable brakes are just as important as engine and handling upgrades.

Check in here: https://www.corvetteforum.com/forums...roadracing-23/ These guys have been there and done it. Not saying Chiselchst isn't knowledgeable, he's a pretty smart cookie. Am saying I'm not the sharpest knife in the drawer when it comes to road course work. I'd like to be, but haven't had the time or inclination to go head first into the road course stuff. Plus, my C6 is about as base as you can get. Engine and handling upgrades are there. Need way more when you start adding curves into the mix. Like Chiselchst mentioned, an M6 Grand Sport has a myriad of road course type of upgrades compared to a narrow body C6.

 

The ZO6 has it all not sure why will you not want to have one but if you insist then like others have suggested go with the Grand sport add aftermarket track brake pads and yes with some nice tires and hopefully get some one to train you on the particular track for best results.

 

I bought a new '08 Base C6 and tracked it for almost 6 yrs here in Northern California. Because I would drive sometimes when it was over a 100 F, I focused on adding modifications that helped keep it cool. Which tracks would you be taking your car on and during what time of the year? For me, my first fluid issue I had involved the power steering fluid here in the summer weather. I chose to put in a Setrap oil cooler instead of an underpully at the power steering pump. This took care of my power steering fluid that was erupting out of the reservoir; pretty easily installed too. One of our road courses we have here is Thunder Hill. This track has a pretty long left hand sweeping corner. Since I drove with Hoosier race slicks and did not have a dry sump oil system, I chose to install an Accusump in my car. I found this not only increased the oil capacity by almost 3 quarts which helped the engine oil temps stay quite a bit cooler but it would also dump additional oil into the engine when pressures dropped. It worked for me and I never had to install special baffling in the oil pan. One other addition that helped me, was the installation of a Dewitt's race radiator. This wasn't totally necessary but it also helped keep oil temps from climbing too high. If you can find a C6 manual grand sport at a low price, that might fit the bill the best. Yet a properly equipped base C6 can sure take a lot more punishment than what most people expect. I wish you the best with whatever vette you end up with.

 

How dangerous is C6Z06 when traction control turned on? I've got some experience in track racing on my Cayman and BRZ.
There are no Grand Sports C6 in Russia, but there are several Z06s. People say it's super emotional car, but Randy Pobst said "Don't touch ESP button if you aren't professional racing driver.
I'm very careful on track, don't take unnecessary risks, never ever had crash on a track or on the public roads caused by me.
Maybe I should take a leap of faith and do something I will remember with smile when I'll grow old?

Z06 is a road car, and i'm sure lots of american drivers without track experience bought it. I won't touch ESP button ever (only on a parking lot). Should I try looking for one?

 

Very dangerous, since your going to be blazing into a corner hot, get under heavy breaking as your trying to steer into the corner, AH is going to kick in, and your not going to be able to make the corner as the car is trying to self correct straight forward off the track instead.

So minimum on the track, you want to be in Comp mode to start with. This will allow the back end to get a little more out, before AH kicks to try to save you. Myself/ my driving style (car loose at all times), car in Comp mode is still fighting me, so always run with all Nanies off instead.

And again, if you don't have High Horse Power race car talent, you need to learn this driving style before you try to hot lap a Z06.
Bluntly, the Z06 has more horsepower than handling abilities, and you do not drive it like say a 911 gt3 where handling and corning are balanced instead.
The simply way to put it, 911 GT3 is a scalpel around the track since it's handling and power are balanced, while the Z06, meat cleaver with the car over powered for its handling capabilities (even when running R7's) instead.

 

I've actually found that turning off all the protection gives some predictability.... I'm used to high hp no traction control vehicles...

left them on when I first got the vette and it felt strange and unpredictable to me when something would kick in...

if I get on the gas I can pretty much tell when she's about to get loose or try to rotate.... but that goes away when the car tries to intervene...

just my opinion of course
