I just checked a bunch of data over at CAC... interesting stuff... and enough to tell me that C5 brakes are not worth it.
C&D got a C4 LT4 from 70-0 in 164ft. They tested 2 different early C5s, 163ft and 158ft.
Even a C5/Z06 did only 152ft from 70. Sure, it's better, but how much of that is tire and how much chassis vs how much the brakes?
If I do good pads, I will exceed any number from a stock C4 setup.
Now, if this was a pre-1988 car... I could see the benefits, big time.
Thought you had HPS's on, right?
Any upgrade from the base brakes (including pads) make a "big" improvement but only because tha base brakes suck.
The C5 upgrade makes another improvement but is still not that great. But it's a bang for the bucks thing, anything above the C5 is expensive but gets you away from the sliding calipers.
