What type of rear do you have ?
My understanding of wheel hop is the tires grab and "wind up" the suspension to it's limits, like a coiled spring. This happens if the rear is not geometrically angled correctly and the car's weight transfers too far ahead OR behind the wound up rear suspension. The springs snap back causing the violent wheel bounce or hop. As you stay on the throttle the hop gets more violent and can do damage . When mine hopped I could never drive through it...it just hopped harder until all was a blur. Once your suspension transfers the car's weight over the center, while under load, it will hook much harder as the energy is transferred to plant the tires not allowing them to spring up. You will of course always eventually slip when over powered but can stop hopping. The day I corrected my live axle wheel hop I was so excited about the new found traction I left the chassis shop, jumped on it hard hit second, then third and BOOM....kissed my little T5Z goodbye !!! All I had left was Gravel in the box.
Oh well....that's why they created Tremecs . If you want to know exactly what is happening have a friend video your rear wheels as you jump on it. A race chassis shop in your area should be able to tune your rear suspension to address the problem before something lets go.
