True, but don't attribute the live rear axle to the fact that it wasn't meant to be a great handling car. It's there because Ford wanted the base model to be under $20k, and they didn't want to invest money in developing a separate independent rear suspension for the GT and GT500 models.C.R.Y. said:dont be all suprised if the mustang doesnt have the best suspension for handling, thats not what its meant for. hence why it came with live axle.

I don't think it would've been possible for Ford to just completely swap the IRS from the old SVT Cobra, seeing how it used the foxbody chassis, which wasn't just different but 25 years old. It could be done, but it takes a little bit more than a few new mounts... it would need a ton of fine-tuning. And the 'Stang fans who like the solid axle are, for the most part, guys who realistically don't own a GT500 and probably never will. Nobody complained about it when the SVT Cobra had an IRS. In the event that the car is a drag strip monster and no longer a daily driver, then yes, the solid rear axle would've been a cheaper, more suitable setup, but I'm sure an overwhelming majority of GT500s are daily driven and always will be. And it's not like an IRS would hamper its quarter-mile performances anyway, it would only increase its cornering prowess. But yes, it should've at least been an option, that would've been a wiser choice, but I feel that the majority of buyers would still opt for the IRS. The price difference between the two wouldn't sway any buyers when it's already a $40-45k car, but the increase in handling and handling feel would already be worth it.C.R.Y. said:they didnt have to develop the irs. the svt cobra had it so they couldve transferred it, but the stang fans like the solid axle because its great for drag racing and cheaper to make. what i think ford should have done, was offer irs as an option. thats where they fucked up.

agreed. it wouldnt have been a direct fit, but more of a starting point for them.
plenty people i know (including my father) said it makes launching the car hard somewhat difficult. even then look at what all the previous mustangs have had. solid axles. even the 5.0, the best 1/4 mile racer has solid axles. the svt cobras needed beefier half shafts and differentials to put up with the power or else they would shatter. the solid axles on 5.0s never had those problems.And the 'Stang fans who like the solid axle are, for the most part, guys who realistically don't own a GT500 and probably never will.

having a solid axle makes it easier to launch harder. and its beefier to handle the torque. thats why it has a solid axle. if the car was built for handling, it wouldve had an aluminum engine, naturally aspirated, and had irs. even then the gt500 with the solid axle outhandles the svt cobra with its irs. owners of both say so. and with the prices being marked up by dealers because of their greediness, im sure noone would want to pay another couple of thousands for irs.
heres some of them who prefer the heavier gt500 with live axle over the cobra with irs even for handling.

...yet every other production car that can do roughly as good or better today has an IRS. Ferraris, Lamborghinis, Corvettes, Vipers, Evos, STIs, SRT-8s, Elises, BMW Ms, Mercedes AMGs, you name it. So clearly a solid rear axle isn't superior for a daily driver that might make frequent visits to the drag strip, otherwise there'd be more sports cars with solid rear axles. If the SVT Cobras had problems that you speak of, that's not so much of a suspension problem as it is a drivetrain problem. Plus those older 5.0 Mustangs never had nearly as much horsepower or torque, so they had to put up with far less stress than even the old supercharged SVT Cobra.C.R.Y. said:plenty people i know (including my father) said it makes launching the car hard somewhat difficult. even then look at what all the previous mustangs have had. solid axles. even the 5.0, the best 1/4 mile racer has solid axles. the svt cobras needed beefier half shafts and differentials to put up with the power or else they would shatter. the solid axles on 5.0s never had those problems.
I never said it was impossible, I just said IRS is the better choice for a daily driven car. If you had a GT500 that was to be your only car (hence being your daily driver) that you might take to the drag strip every now and then but keep close to stock but Ford gave you the choice of having either the solid rear axle or reasonably developed IRS, what would you pick? Thought so.C.R.Y. said:plenty of people daily drive solid axle mustangs with no problem
Bullshit, the reason why the solid axle is there isn't because of launching. Yes, it can benefit straightline acceleration from a dig, but that wasn't the reason for its placement in the Mustang lineup. Like I said before, it's because of Ford wanting to keep the gay ass Mustang V-6 below $20k first and foremost, then it was to keep development costs down. Every other modern American musclecar has an IRS, some of which are just as quick down the strip.C.R.Y. said:having a solid axle makes it easier to launch harder. and its beefier to handle the torque. thats why it has a solid axle. if the car was built for handling, it wouldve had an aluminum engine, naturally aspirated, and had irs. even then the gt500 with the solid axle outhandles the svt cobra with its irs. owners of both say so. and with the prices being marked up by dealers because of their greediness, im sure noone would want to pay another couple of thousands for irs.

i agree. it is better, but the solid axle still isnt bad. if i had to choose it would depend on the cost. if its another 3k id rather stay with the live axle as it would bother me as much. but if it was like 1k more (which i would doubt) id get it.I never said it was impossible, I just said IRS is the better choice for a daily driven car.

whats the V6 gotta do with it? i doubt the V6 has the same live axle as the GT500. and yes other cars do use irs and are fast. but the live axle isnt nowhere as tricky to launch. everywhere i read the irs is a pain, just look at the gto as an example.Bullshit, the reason why the solid axle is there isn't because of launching.

Really, pick a new car to talk about please. Or at least a different performance measurement.

But here's the difference: the live axles on the GT500 work, while the leafsprings on the C6 Z06 work well. Its Nurburgring times are clear, objective testaments to that, which is why I don't really have anything bad to say about the Z06, despite its rear suspension being pretty archaic.C.R.Y. said:the live axles were never the best on other cars. the point is that it works on the mustangs and work well. thats like saying the leafsprings on the C6 Z06 suck because its old. it still performs good so why not? people are satisfied with the handling of the gt500. no, it wont outhandle evos or vettes. but it still handles good for a car of its kind.
The V-6 has EVERYTHING to do with it. I'm not saying that the rear suspension of the base Mustang is identical to that of the GT500. I'm saying the reason why the GT500 has a live axle is because the V-6 does. Like I said before, the live rear axle was used to reduce the MSRP of the base model, and then Ford chose to use different different suspension bits in the sportier models to sharpen handling as higher performance becomes the greater focus. While I'm sure the GT500's suspension hardware is probably quite different from the base model's, that suspension setup is still attributed to it.C.R.Y. said:whats the V6 gotta do with it? i doubt the V6 has the same live axle as the GT500. and yes other cars do use irs and are fast. but the live axle isnt nowhere as tricky to launch. everywhere i read the irs is a pain, just look at the gto as an example.
This is my view... while it's true that regardless of where someone lives in the U.S., quarter-mile drag strips are more numerous than actual road courses or race tracks. In that sense, quarter-mile acceleration seems like a more practical aspect of performance to put stock in. However, outside of the drag strips is the factor of daily driving. Personally, I don't launch at every red light, rushing toward 100 mph. Suddenly, superior straight line acceleration, while fun and adrenaline-pumping, doesn't seem so important. But cornering prowess is utilized more frequently... when making sharper turns, going through on- and off-ramps, swerving out of a lane that might have a car slamming on its brakes. Suddenly daily driving seems a lot more fun, thanks to curves built into the world around me combined with a well-sorted suspension, all while not having access to a nearby track. (I'm not suggesting people go all-out and drive sideways through city streets, I'm just saying a little fun can be had safely here and there in your daily routine... it's about finding out where to get an idea of what your car's dynamics are.)C.R.Y. said:i talk about the 1/4 mile because its the only thing i would be able to do. i live in newark, theres no road atlanta around here. only englishtown's raceway park and atco raceway. why care about handling as much when i wouldnt be able to put a car through corners hard without putting someone elses lives in danger.
the mustang does well with the live axle. thats what im trying to get at. no it wont outhandle alot of cars. but its good considering it weighs 3900lbs. just because theres better handling cars, doesnt make it lesser. thats like saying a evo is shit because theres a Z06 that does everything better with rwd. it doesnt make the evo any lesser. its still a good car.DeeezNuuuts83 said:But here's the difference: the live axles on the GT500 work, while the leafsprings on the C6 Z06 work well.

I don't doubt that, I completely agree. The reason why I kept counterarguing was because it seemed like you were saying that the solid rear axle was the better choice for the GT500, especially for drag racing. Solid rear axles might be a better choice when you start to reach four-digit horsepower and torque numbers, but anything less won't need one to the point where the benefits outweigh the drawbacks.C.R.Y. said:the mustang does well with the live axle. thats what im trying to get at.
But the problem with your analogy is handling feel. While the Z06 will hand the Evo its ass on any track that doesn't involve traction issues (rain, snow, gravel, dirt, mud, etc.), the Evo is still a great handler both objectively and subjectively, with excellent numbers and compliments. Objectively, the GT500 puts out some awesome numbers, suspension setup aside. Subjectively, several test drivers in magazines, TV programs and online publications say that while the car puts out results, the handling didn't feel very refined and wasn't as confidence inspiring as other sports cars that they've driven. However, some people prefer handling feel over results, and vice-versa. Driver A might like to take freeway on-ramps at 60 mph feeling well-planted while Driver B might like to feel like he/she is on the edge of spinning out at the same speed. Different strokes for different folks.C.R.Y. said:just because theres better handling cars, doesnt make it lesser. thats like saying a evo is shit because theres a Z06 that does everything better with rwd. it doesnt make the evo any lesser. its still a good car.
While what I'm saying isn't too pertinent t the topic, I figured I might as well elaborate. The incident I was thinking of when I typed that surprisingly was a mix of fear and excitement. I was going around 60 mph down a three-lane street (50 mph speed limit), and all of a sudden, a BMW in front of me slammed on its brakes. I figured even with my Brembos, I couldn't stop in time, so I swerved into the lane next to me (which I knew was clear), and I barely missed the car. Had I been in any car that handles even the slightest bit lesser--like an STI--I would've hit the car. The reason why I say that (other than the fact that I've driven an STI extensively) was because the car's quick steering ratio, suspension and LSDs played a significant role in pulling me out of a potential accident. The steering ratio only required me to give a slight but quick jerk of the steering wheel, the suspension helped the quick reaction, and the LSDs kept me planted as soon as I countersteered. In an STI, I would've at least nipped the rear corner of the BMW's bumper, but even if that happened, who knows if that would've been enough of a nudge to send me spinning.C.R.Y. said:if i seen a car stop suddenly in front of me im gonna be scared as shit, not having fun.
DeeezNuuuts83 said:As a side note, I was reading the current issue of some Mustang magazine yesterday, and in their road test of the GT500, they did a 0-60 ft time of 1.9 seconds and the quarter-mile in 12.41 seconds (no published trap speed)... pretty impressive stuff.
I assume so, the article stated that the car was "bone stock." But yeah, 1.9 is really good for such a torquey RWD car. But then again, I'm sure that the test drivers for a Mustang magazine know every single trick there is regarding how to control them, so they'd probably be the most suitable drivers to get the best times for publication purposes.C.R.Y. said:yeah. i didnt expect a 1.9. was that on street tires?

C.R.Y. said:so what it weighs 1700 kgs and has a live rear axle. its still fast. you might as well diss supras because they use turbos bigger than my head and muscle cars because they use 572 ci engines. why diss and not appreciate. thats the point of being an automotive enthusiast. something you dont seem to be. ppl like me and Deeznuts appreciate all types of cars. whether theyre stripped, have big laggy turbos, or weigh alot. i dont like the 69 dodge chargers, but i give them respect because they are pretty fast.
The GT500 is a semi-modern, relatively cheap modern muscle car. With all the advantages (big engine, good power, fun) and drawbacks (hamburger technology, unrefined) that come with it. Nothing more, nothing less.
