Hi all. I recently submitted my Cobra data to Tilton:
Their response was:
Hello Greg,
With the information you have provided on the MCBS form, predictions for your master cylinder bore size are :
At 100 lb pedal effort: Front 11/16 “ MC and 1” rear MC with a 5.1 pedal ratio
At 85 lb pedal effort: Front 5/8” MC and 15/16” rear MC with a 5.1 pedal ratio.
This is a prediction and the final bore size will be determined by the driver testing to achieve the best braking combination. Balance bar adjustment will change front to rear brake characteristics, the final decision should be based on track testing.
Cheers
Greg
