I was looking at the Wilwood front brake kit for the Fiesta and they have a nice clearance diagram with measurements. I thought spoke clearance for the calipers would be the challenge, but after taking some measurements of my 16x7 Sparcos last night I am concerned about the inside diameter of the wheel clearing the calipers :-/ Is anybody already running this combination? Based on my measurements I think they may clear, but I am pretty sure the balance weights installed by the Tire Rack will interfere. I am not considering this upgrade so much for increased braking as I am for reducing unsprung weight. If the numbers posted by Joe@2J are accurate, 11 lbs. reduction per wheel is pretty amazing.
