Way back when, I used to be a serious autocrosser. In my neck of the woods you were either a round tracker or a drag racer. The exception is the Florida panhandle. Because Pensacola is a military city there has always been a more diverse group of people there. Somehow I got involved with them. Over time I got tired of the wheel hop, saved some "tight" money and purchased a set of Ansen Ground Grabbers from a local speed shop.
These things did away with any wheel hop! They were awesome for straight line but they were awful for autocrossing. Depending on the severity of the turn, I would lift the inside rear wheel anywhere from 1" to 4". A spin never makes for a fast time. So I sold these things and then got a set of slap bars. They worked and they are still on the car today.
By the way, it doesn't matter that the car hasn't turned a wheel in 25 years. It has been garaged since '89 and just waiting for me to put up the money to have it restored. It was bad ass then and hopefully it will be again. Will I autocross it again? No. But I do want it to handle if I get one of those wild hairs as I so often get! I'll save my autocrossing and roadracing for the other car in my garage, the Titan MK3. I took Don (Don65stang) to an autocross last weekend and you see what it did to him. I even let him drive my wife's restored '74 MGB on the way home.
