||Get some data to back up claims.
The more rapid the deceleration, the more weight shifts to the front, the more front bias you need. Suspension and tires play a big role here, but that's only further compounding the problem of discerning who has better technology.
Not that I've been combing through the data but I haven't seen a single person post a stopping distance as a result of their brake upgrades, regardless of whether it was a pad change, stainless lines, BBK, etc.
I no longer have a set of stock brakes to compare against (in addition to my car probably won't be off jack stands again for a year), nor do I have readily available access to a closed course to perform this test, which really should be done back to back to keep conditions consistent (tires, roadway, temperature, dryness, etc.).
If somehow the stars align and I'm given the opportunity to produce these results I will gladly share them.
