There have been several posts on this subject lately. Do a search.
Some people don't have wheel hop, and most do. Since the cars are nearly identical, I'd say tire pressure, and most of all, the road surface. If on a slippery pavement, you simply can't hook enough to encourage wheel hop, and on a great surface they stay planted. The drag strip is the worse place to tear up your car, as the track has to much variation in traction. It goes from extremely good to fair, and this can really get you in trouble. Heated up slicks don't have much of a problem. We've all encountered roads that have these characteristics. Wheel hop is the tires attempt to hook up, but when they break loose they unload on the suspension, and this starts an osillation in the suspension. My car has nearly zero wheel hop, but so many things have been changed on mine to acheive this. Your best bet if you want to leave your car mostly stock, is to modulate your throttle till you overrun the ability of the engines torque to do this. The mods that I've done really have so many other advantages, as a matter of fact, wheel hop was not the primary reason they I done these.
Tire temp is very important, and tire pressure also. Someone above claimed their tires don't wheel hop when cold, well they must be spinning like mad, and can't even hook enough to hop. When you spin to much, this is when you risk severe wheel hop, for when the tires catch hold, they are going to hop so much worse.
If you look in some of my past posts, there is some good info from me and others on this subject.
