My big brakes up front are the Sierras, not Wilwoods, but that was six years ago. Wilwoods are pretty much the same. See, the real problem is that once you start "upgrading" in one place it cascades down to other places. Getting the outboard braked rear, which has bigger brakes, makes you want to get the bigger brakes up front, which makes you want to get the six pin hubs, which you don't need either (and nobody can tell you even have them), and then you might as well throw in the extra venting in the wheel wells for it all.... But, if you're getting a used ERA, why are you spec'ing out stuff like this anyway? It's not like there's that much of a choice in used ERAs. You pretty much have to "take them as they come."
