Switch to disc in rear

Well, safer is always first in my book, but, I have no actual practical experiance with aftermarket brake systems. The stock parts have been good enough for what I was doing. Best runs were high 11's. Stopping power was not an issue @ 110+ on factory parts in a full weight E body.

Yup! Have to agree here. Excellent example is that your e-body's rear brakes work fine and are completely safe. BTW , were they 10 or 11"?
