Roy, I think this is a really good thread, as I have similar questions/concerns. I've driven high horsepower straight axle cars and ones with independent suspensions (i.e. Corvette).
My experiences with the former (straight axles) is that they tend to stay in a straighter line under brutal acceleration (i.e. less fish tailing). And when they do fish tail, a little less pedal ('back pedaling") usually straightens them out.
But my experiences with the 'Vette (late C4 design) are just the opposite. Power shift into second or third (at speed) and this car will literally "lurch" up to one entire lane to the left. A very uncomfortable feeling if you're not anticipating it. Perhaps some stiffer bushings on the trailing arms ("dog bones" for enthusiasts...I call it the four link portion) would correct this condition? And if that's the case, then perhaps the same medicine can be applied to a Cobra IRS?
