Leverage and total swept area both are increased. Larger disk= same size pads traveling farther per revolution and touching more disk.

 

Not sure you need more rotor swept area, actually. I installed the Galfer SS lines and EBC ceramic pads. I now have more brake energy that I can possibly use, with no heat-related loss of performance.

929/954 discs can be purchased relatively cheaply. Those discs are 1 inch larger than the ones on the F4i, a considerable difference for something that weighs less than 400 pounds and yes larger discs does make a difference in braking power.

Although they bolt right up to an F4i wheel you cant run them on an F4i (98% sure) because the F4i calipers would not mount in the proper position for the pads to cover the disc. You would have to switch front ends to make that work.

Stainless steel lines is always a good upgrade. I think the reason they are better is because rubber lines expand as they heat resulting in less pressure. SS lines do not expand so there is no brake fade.

 

i would say the 929 conversion or the 954 conversion as well. But as of now what type of pads are you running Double HH's? i would try some more abrasive pads first.

look at it this way whats the point of extra stopping power if your front tire doesn't have enough traction to grip the road and utilize it?

 

I got EBC ceramic... will put them on when season begins! I don't think my guts are letting me get anywhere near the stopping grip of my front DOT tire anyway :P
