As you can clearly see there is the production car frame rail, its a seam welded roll cage added to the production car frame.....I didn't make it up...LOL

 

Specs (2005)
Engine : LS7R 6980cc V8 Naturally Aspirated
Transmission : X Trac 6 Speed Sequential
Brakes: AP Racing 4 piston front and rear
Wheels: BBS 18x12.5 front, 18x13 rear
Weight: 2435lbs
Suspension: Double wishbone, toe-links, coil springs over adjustable shocks, roll bar
Horsepower: 590bhp@ 5400rpm
Chassis: C6 based with Roll cage
Bodywork: Carbon Fibre
Tyres: Michelin

 

This CTS-v incorporates numerous performance upgrades to ready it for track work. The body/chassis was sent to Pratt & Miller (which also runs the team) to have the body seams welded, a full rollcage installed, side-impact honeycomb crushboxes affixed, and carbon-fiber hood/doors/trunklid added. The factory short/long arm independent suspension remains but has been upgraded with Penske coil-over shocks. Underhood, the R receives a Katech-built LS2 V-8 with 12:1 compression, a custom roller lifter camshaft, and CNC-ported heads. SCCA rules mandate a special air-intake restrictor that limits the LS2 to about 515 horsepower. Unrestricted, it would push the dyno needle to 600


However this is the last post in this thread about this, lets get back on topic here.

 

A frame rail piece-mealed for dimensions is not the same as a complete chassis. The cars still have to use the same dimensions as the factory car. GT2 requires a complete chassis for racing with minimal modifications to the chassis at all. I believe no soldering to any parts of the chassis for stiffness. Either way, that chassis will look nothing like the C6R that will race in GT2 on a complete and hardly unmolested Corvette chassis.

To be considered Tube framed doesn't mean the whole car is tubed. Only significant portions have to be.

 

You can admit to being wrong, I do all of the time!

You said that they were a purpose built tube frame car car, they are not...they even use the standard C6 balsa wood floor. I will post a cutaway so you can see it. Its simply a C6 chassis with a weld in roll cage no part of its a tube frame. And you said the CTS-VR was a tube frame car, and its a seam welded unibody with a weld in roll cage, no tube frame in that car at all.

Quote : Like the C5-R before it, the Corvette C6-R starts from production roots: the
same hydro formed frame rails that roll down the assembly line at the Corvette
plant in Bowling Green , Kentucky are sourced for the structure of the race car.

 

I did know that the C6R uses the same hydroformed frame rail as the C6Z, it was a big selling point with the car. But you should also know that if you give a frame rail to a race engineer and tell him he can go crazy with it that it's not really like the production car.

Gm sends a frame rail (only) to Pratt & Miller who builds the rest of the car except the motor, which is built by katech. It's still a chassis modified and designed completely for racing and has very little ties to what drives on the street.

I do not know all of the details, but I do know that is not the same as a GT3RS body with a cage in it. Neither does it compare to the M3 GTR or the Ferrari F430. There is no need arguing over semantics, the fact is that the cars aren't nearly the same, when small differences can make a huge difference in racing. A GT1 corvette isnt' even comparable to a GT2 corvette (even down to the production specs of the engine). That is my only point. And that a frame rail can't be considered as a complete chassis comparable to a GT2 car.

This is from GM themselves.

"The key is that the new GT rules are very much based on today's GT2 cars, so there will be a lot more production content, a lot more requirement to stick closer to what the cars are on the road. Any substitutions have to come from another large volume GM product, so we'll be sticking a lot closer to production and you'll be seeing a lot more of that content."


I do not wish to turn this into a big debate, but lets nont try to act like the GT1 corvette is anywhere near the same as an RSR,430,GTR,Comp Coupe or the like. Not even close. When the GT2 Corvette is complete

 

What? They used the regular steel C6 frame, rather than the aluminum Z06 frame in their C6 program. I know that for a fact.

 

Yes, steel is heavier, but more rigid. Aluminum is flimsy, but they are still hydroformed. But it's still a corvette frame. Just not the aluminum Z06 frame. There is also the issue of welding cages into aluminum cars, can't remember exactly what.

Oh, I just realized I put Z in my last post, my mistake, the new C6R's will be using aluminum though, at least when they originally started they were supposed to.

 

Does anyone expect Porsche to make a new Carrera GT?

 

Hate to toot my horn, but go to post # 48.

I see your cars and your address - is your name Buffet?

P.S. glad we're talking about P-cars again.

 

I read it, but you didn't explain why you don't think they'll make a new CGT.

No, I am not Buffet or a Berkshire guy.. That's a good thing these days..

 

Its the end of an era, supercars (Superloses) are over and done. I think many of these companies will be happy to survive the next 5 years. There are much better things to use idle cash for then pump it into a CGT project IMO.

Time will tell, but I doubt the government or the media will be backing 500k sports cars anytime soon.

 

GT1 road car successor and an LMP1 entry at Le Mans to shove it in Audi's face. Oh, and a Cayman RS...seriously, they should get to that one

 

porsche will always build a supercar. maybe not a new "carrera GT" but they need a new supercar to stay with the competition. so porsche will always build a range top supercar to fight against nextgen ferrari enzos .....

 

Porsche is very business savy, I find it hard to believe they will compete with other brands they own in major competitions. Audi is a Porsche brand now and will be even more increasingly as time progresses.

Porsche will likely expand it's racing program, but I doubt it will be in LMP1 now that they are exercising their options in VW stake. Maybe something in the revised GT1 program or a new LMP2 car, but I find it hard to believe they'll go heads up with themselves under different brand names.

But on the other hand Porsche takes pride in it's overall and Lemans victory numbers, so I could be all wrong and they may show up again, but with them showing interest in Indy Car, I'm probably not as the Porsche racing program can only support so many different series at once.
