I'm doing some needed maintenance on my reace car as well as finally getting around to installing my new BSI trans (4:32 ring and pinion with Quaife and expert Stu rebuild!) My first question has to do with the steering knuckles.... which is better? Are the later (bigger?) ones better? I'm replacing these parts with new and want to know what to order. Also can anybody give me an idea of lap time improvement at Summit Point going from the std ring/pinion and no limited slip to the 4:32 and Quaife? I know that I'm going to go thru a learning curve with different shift points and being able to roll on the throttle a little earlier with the diff, but can anybody tell me .25 or .50 sec/lap? Joe
