Not much progress has been done in the last week, mostly parts research and search. New studs are coming from Ireland Engineering (http://www.bmw2002.com/). The old studs were Moroso 7/16 diameter and 3 long. the new studs are once again metric. They are made by ARP. Thread is 12x1.5 and the length is 65mm. Another change int he car will be the front brakes. Thanks to the recommendation from Jeremy i an going away from Hawk Blue bads since they seem to overheat and cook my rotors in autocross condition and moving towards Hawk HPS pads. They can be found at TireRack (http://www.jdoqocy.com/click-1875887-10399972). Parts should be installed by the end of the week and have the car ready for the next event.
