im saving for the griggs setup with adjustable koni coilovers at four corners. very much like the mach 1 tested in the lastest issue of motor trend. that mach 1 took the slalom at more than 69mph(4mph faster than the cobras irs).
with the griggs i would keep the solid axle. but i know a lot of cobra guys swapping out the irs for the live axle just to get rid of wheel hop. if your looking for a solid axle good luck. also griggs ive heard has irs setup that does a good job at eliminating wheel hop. i would give them a call as well as mm and see what they say. :burnout:
