I'm am going to start this off by admitting I have never driven an '05, so I might be pretty off on this.
Does anybody else find it hard to believe that a '05GT out handles '03-'04 Cobras and 350Z Track Models??
The hardware says it should be impossible. The tires on the GT alone should make all of this impossible. They are 55 series all season's for cripes sake. The Cobra has 275/40 Goodyear F1's.
And a strut front end, too. Can't even compare to the 350Z's double wishbone's ability to precisely locate the tire.
The car has a solid axle, and no mater how good you tune it, motions on one side are going to cause undesirable action on the other side.
I love the new GT's, but I can't help but questions these kind of comments being made by both magazines and repeated here over and over?????
Its not that hard to belive;
The '05's front suspension is a coil over strut very similar to the strut front suspension that BMW 3 series uses, including the M3. So are you suggesting that we start arguing that an M3 can't possibly out handle a 350Z because it has struts?
The 79 - 04's Mustang's front suspension is an abomination, including the Cobra. It is a screwed up modified MacPhearson strut that has the springs in the wrong place, has bad mounting points and has a roll center that is way too low.
The '05 GT has 53/47% front / rear weight balance verses the Cobra that has 57 / 43 F/R weight bias. Ever wonder why those dinky under-powered Miatas are so fast on an Auto-X course?
The '05's unibody is 50% stiffer in twisting and 30% stiffer in bending. The unibody is stiffer than a BMW 3 Series. Unibody stiffness does wonders for handling as it lets the suspension do its job w/o having to compensate for unwanted structure distortion.
IRS has more to do with comfort and handling on bumpy roads. On smooth roads a good live axle setup like the 05 has will be as good if not better than a kludge IRS like the Cobra has, which was a modified version of the MN-12 IRS adapted to fit into the old Mustang. The Cobra IRS is a long way from being an optimum design.
As far as the tires go, it really doesn't matter what you put on a car that has a flexy unibody and bad suspension design, fat sticky tires will not make up for all the other short comings of that car.
The most important thing is that the '05 is a clean sheet design that was
specifically designed to be a sporty - performance car. ALL prior Mustangs were based off low cost economy cars (Falcon, Pinto, Fairmont). The last Mustang started out as a 1978 Fairmont that was an out-dated design the day it was introduced). That same basic Fox platform design has been band-aided for the last 25 years.
