Like i said above, just got my car back from a NC chassis shop, my problem was i only had 1 inch of shock travel, It was trying to unload the rear tires, this was causing my car to chatter slicks on take off, the chassis shop had to redo the 4 link and make longer shock mounts, in doing this the car sits 4 inches lower in the rear. PM me and i will give you the shops number.
