So what is the goal? Bragging rights, bling, mechanical mounting challenges, etc? Too big of brakes may make you warm and fuzzy and peace of mind, while you study the bumper of the guy that just passed you. Unsprung weight, and the flywheel effect mentioned which is valid at BOTH ends of the straightaway, and normally cost, which the Op has overcome. are all concerns, bottomline, the wrong solution at a good price, is still the wrong solution. Now if the OP is overheating his ducted brakes repeatedly, step up, but might want to figure out how to lighten the car, which has many benefits, reduced braking requirements being one.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
