go solid axle. it made a world of difference in my car and i didnt see to much handling diff. I picked up alot of power mostly because when i did the swap i put exhaust on my car but you can really feel the weight diff.

I don't like driving an 1812 wagon cart
and
I have to match it up to my 01 cobra engine.
Why not just buy a cobra? Because there's no fun in that!

a solid axle is the shit! Nuff said. You will not regret it at all, it was by far the best mod I have ever done to my car.
MR PA1N said:Are the 94-98 GT straight axles the same as the 99-04 GT axles what are the differences if any :shrug: with one is better :??:
Has anybody looked into the 05 mustang GT straight axels and if those can be used?

Dingleweed said:The pre-99 solid axles are 3/4" narrower on each end than 99+ solids. No big deal there, just need some wheel spacers or a slightly different back spacing if you don't want the wheels to look too tucked in. Also, the pre-99 use 12 mm bolts between the lower control arms and the torque boxes whereas the 99+ (including your IRS) solids use 14 mm bolts. So your bolts that fit your torque box holes will not go through a pre-99 lower control arm. Options there are either to drill out the older control arm bushing sleeves (not ideal), buy new bushings for 14 mm bolts, or buy aftermarket lower control arms for 99+ solid axles (that's what I'm doing )

viperbluelx said:I did the solid axle swap on my old white 99 Cobra and for a lot of dragstrip abuse it's the only way to go and feel comfortable about launching at 7,000rpms.
I now have the red 99 Cobra that was stock when I got it and I'm going to build up the IRS and keep it. 03/04 Cobra halfshafts and a 31-spline traction lock unit with urethane IRS bushings should take all I can throw at it with my all motor setup making around 300rwhp. If I were to go with a blower or nitrous later I'd consider the solid axle swap though.
