CPP OEM Big Brakes vs. Aftermarket

[stgil888]

Mid way through a build right now and trying to decide between a set of CPP big brakes using OEM calipers (not sure where they come from) versus going with an aftermarket brake system.

If there's anyone on here who has used, or at least driven, both types, any input would be appreciated.

I'd like to get this figured out sooner rather than later so I can choose wheels/tires/rear axle to fit.

Will not be a track car, but do want it to stop fast. I admit I like the look of big Wilwood...etc calipers, but don't want to have to run 20's to fit.
