The government does not specify these cars had to gain weight per say. The weight gain is a result of GM/Ford having to meet crash worthiness standards set by the government, essentially adding more safety features, increasing the size of body/crumple zones. Ford and GM could have used a lot of carbon fiber and aluminum, but would have increased the cost considerably.

 

I HAVE A BUDDY THAT IS A DRIVING INSTRUCTOR AT Bondurant AND HE HAS TESTED A FEW VARIATIONS OF THE ZL1 FOR GM WITH OVER 600RWHP....

 

Ya jealous?

 

Apparently he forgot that Chevy still uses leaf springs in the Corvette, guess that means Corvettes suck...

 

I like my transverse leaf spring in my vettes. Its nostalgic just like Model T came with.

 

Not a bad move considering a live axle swap was on the mod list for a lot of the 03/04 Cobra owners...

 

yep...I tried everything to keep wheel hop at bay, poly IRS subframe bushings, poly rear control arm bushings, derlin differential bushings, QA1s, IRS subframe bracket, IRS differential brace...basically a small fortune in parts and would have just been better off with an 8.8 swap, while the above mentioned parts cured a lot of the wheel hop, it did not get rid of it entirely.

 

Well then my F150 suspension sure gets the job done with traction. My car hooks pretty good on the street now and all I did was change to aftermarket C/A's and some good struts and tires.

Now if we are talking about road racing (which I know very little about) I would think the IRS would be the way to go??

It's not enough for a 55k car to go fast in a straight line. Not to mention ride quality...


Transverse leaf springs are a huge improvement over a traditional live axle. Not to mention that at 3200#lbs with the transmission in the rear, the Corvette is in a totally different class of car.

 

 

The only turn I'm worried about is the one at the end of the drag strip lol

 

if anybody is worried about a pony car turning... just order up a boss 302.

 

That must bring the mph down at 100mph then right? I wonder what they kind of mileage they get at 100+mph...

 

You're out of your element, Marty.

 

thing every1 is missing is they put a cage in these test cars... they are already 200lbs more with the cage...

 

the 609 hp on a dyno was also on a dynojet... take that for what its worth as well

 

All of the big name tuners in Houston use dynojets.

Looks to be a sick car in stock form. I'm glad my Z isn't stock!

 

I think people fail to realize how bad *** it is that something in STOCK form, from the factory, with a warranty is making over 600hp to the tires, for only 6X,000.


Not a bad ******* deal.

They accounted for the straights, and the ZL1 is still faster (and more importantly more confidence inspiring). So I am betting the 1LE will be also.

I'm not denying that the 2013 GT500 will haul *** and smoke a Zl1, or that the 5.0 Coyote is a fantastic engine, it's just my opinion that the mustang needs an IRS badly. Especially considering its price and that all its competitors do.

 

Awful argument. Most people do not have the Mustang Dyno's calibrated correctly or taken the time to do so as they can be VERY comparable.

Regardless, it is a tool and not the end all be all measuring stick.

Dense people on this board.
