I took a ride in both cars at carlisle, I was impressed. I really didn't think the 4-door taxi would make that first corner. A bone stock one would have ended up in the weeds......My son and Tim talked me into buying a kit for my '70 Barracuda, when we got home on Sunday we started on the rear springs, the instructions were right on, great kit. But of coarse I broke one of the shackles so Drew or Jon I need a shackle kit sent with the rest of my kit. All the guys and girls new the product well and were very helpful.
