Default Contemporary Brake upgrade

Okay, no opinions on that one so I will share what I have decided. I am selling my Wilwood Superlite calipers with 1.38" pistons, buying a set with 1.75" pistons, and putting the pistons from the Jag Series I front brakes in the rear (bottom option). I may also put a porportioning valve in the rear line to get to the magic 66% number! Let me know if anyone wants more details on this upgrade,
--------------------------------------Front Brake Bias-- Front Tire Force
--------- Jag Series I----------------------62%--------------2910
--------- WW 1.38", Jag 1.75"--------------60%--------------2660
--------- WW 1.75", Jag 1.75"--------------70%--------------4114
--------- WW 1.75", Jag 2.12"--------------62%--------------4114

Wilwood 1.75" Brake force increase----------------------------141%
