I would never use a IRS for the drags, they were not made for that application. Good ole 9". Wheel hop can happen with any rear end, any car, most of the problems comes with setting up the suspension. Sometimes a simple shock change will correct the problem. Using a four-bar with a panhard and softer shock settings will be the best for the drags. You don't hear about such problems with the cobras because their so light weight, so they don't get axle wrap as heavier cars.
