Why does the 03-04 cobra coupe weigh so much more then the 1998 cobra?

Is the IRS heavy? Im curious as to where all the extra weight comes from

The difference bewteen the IRS and the live axle is 70lbs, stated. It also reduces the unspring weight of 125 lbs against the live axle

I never got the IRS. Why would they put that in the Cobra and give us (non CObra) the "better" live axle?

I dont remeber, did ford say they were going to put the IRS in the GT500?

Are you saying it is or isint a big deal, it sounds like your meaning it isint. 250 pounds is a LOT of extra weight, I remember seeing a weight table that said 100 pounds was equal to 1 tenth, so that would mean if it wasnt carrying the extra weight it could be 2 and a half tenths faster. May not sound like a lot but it is huge when your going for max ET.

^ Yep! When i gave a friend a ride down the 1320 (200#s according to him) my trap went into the 106s and ET into the low-mid 13s (bad traction had alot to do with the ET).

Ford tried to make cobra's a handling car, as the GT was straight line oriented...

the dick thai-tang doesn't want an IRS in the GT500 because it weighs more and cost too much

The IRS is much better for road racing and getting into the twisties, which is what the Cobra's original function was in the first place. Owners were the ones that decided to turn them into "stop light warriors"

....not to mention the IRS rides a lot better.

Ford should have pulled their heads out of their collective asses and given us buyers the option of choosing between the IRS or live axle. ...but no all we get is spoiler delete or chrome rims as the only two choices.

This is true. Although I don't think it hurt sales at all. I'd be very able to live with the IRS rear end when you consider all of the other goodies you get with the package. I guess the flack they got from strait line enthusiasts that bought the Cobra's must have rubbed off a little though, since the Mach 1's still at least got the solid axle.

Ahh well, the IRS is still workable none the less. Besides, it’s nothing some beefier half shafts and harder durometer bushings won’t fix.

Yeah, same here. It's such a sexy piece, who would want to.

I've seen quite a few "spoiler delete" Cobras and I think they look silly.

They had to add several hundred pounds to these cars to keep them on the ground! You see the owners heads instantly begin to swell and inflate from the first test drive.(like a hot air ballon) Having 425+ hp has been known to cause some to combust. I'm hoping one day my head will begin to inflate in a 04 Cobra.

What, did you scrap that idea too? After all the bitching and complaining about 3.73 vs 4.30 gears.
