@USMUSL its not necessarily about axle strength, but more about wheel hop and traction

It's been well established that the solid rear axle is capable of handling well more power than an IRS, however, IRS have been known to withstand upwards of 600RWHP, though not for long.

Live axles are stronger than the IRS because they are one solid piece, which makes them better suited for drag racing, because more power is put to the ground through a solid when used for that application. An IRS is better suited for road races like autocrossing because each wheel is independent from the other and the wheels can drop and raise with better range than a solid (live) axle can, which creates better grip and handling. On some of the newer cars, more or less power can be applied to the single wheel with the most need for grip and power. Hope that helps some.

Could Some1 explain to me the pros and cons or IRS and Live axles! Thnx

These guys do know, which means they're just straight up lying to everyone...What fags.

You would think that with the experience of these guys...they'd know the difference between bhp and rwhp. 447rwhp divided by 0.9 = 496bhp. Sounds about right to me! It's still 1000lb overweight though.

yes it has been proven, there is even an old artical about it about 3 years ago in a muscle mustangs fast ford magazine. some guy had a nearly stock 5.0 with a wicked rear end beating modded and stock cobras with twice the hp and irs around a track. (but up to the driver also) yeah the car is a beast and has great potential but i still say fat pig lol. but a good pig.

no other car i have ever seen can run in the 9s almost stock cmon ppl this car is a beast and it would require just as much money 2 get a gt in2 the 9s

I seriously doubt a live axle could be made to handle BETTER than an irs. Almost as good, sure, but not better. And I agree about the foxbody. The GT500 is an expensive pig.

yes that is true, id say most americans dragrace there cars, not roadrace and autocross them. I dont understand why they would put it on a dyno when the motor is rated at 500, its not 500hp to the wheels, all manufacutes measure hp with the engine alone on an engine dyno. Also top gear says that the cobra had 300hp, but i think they forgot about the 03-04 cobra the had 390-well underated but more like 410hp. Those cobras have irs and under hard launches at the strip they break. I guess they dont understand that an old school live axle can be made to handle just as good as irs or even better and its been proven. But i woulndt want that Gt500, id rather have a fox body and the rest of the money in mods :)
