have been thinking of picking up a 99 or 01 cobra. not really into drag racing would like something that handles better. question is does the IRS make a huge difference over the solid axle? I have only driven solid axle mustangs. thanks for any input

if u had a built solid axle with panhard and torque arm, and a built irs full bushings, the irs would grab better on uneven surfaces, that was one of the biggest differences, i read a comparison maximum motorsports did on their own track car after they swapped it to irs and tossed the PHB/TQ

What he said above, plus a full built solid rear is would probably make your kidney explode if daily driven, I converted my old 82 GT to IRS w full bushings and braces and it was a dream even on rough roads

Post above sums it up perfectly. MM chooses IRS over solid for the win!! IRS is the best for handling!!! I have had 3 IRS cars!! All were also a dream to drive!!!

Love my IRS swapped car, it rides comfy on the highway and I can keep my foot planted over uneven pavement where my phb/ta coupe would be dancing all over the place at 1/2 throttle.
some say it's not as fast in a straight line, but if you have the $700 fulltiltboogie delrin bushing upgrade in the IRS there's going to be no wheel hop, it transfers weight and plants differently than a solid axle but it's fine for mild >11 second cars.
A lot cheaper to have a great setup in the rear too, a SRA needs a phb/ta/lca's/shocks/coil-overs.
The IRS just needs delrin bushings/diff brace/coil-overs really.
I haven't done the delrin bushings or coil-overs on my car and don't plan to, it handles good enough for me at the open track to chase down much faster cars through the corners and it sticks like glue.

I really liked the IRS on my 03 Terminator when I had it. But now that I have 99 Cobra I'm doing a SRA swap. It all depends on your goals and power levels. An IRS is a lot more expensive to maintain if parts break vs an SRA. I love the handling aspect of the IRS but looking for 600rwhp to 700rwhp it's SRA for me this time. I do have the TQ A, Panhard bar and sway bar that will be installed. I'm sure I will be loosing some of the cornering fun by going SRA, but my plans are now to pick up a Hellion TT kit with 61mm turbos so SRA would be more beneficial for 1/4 mile usage.
