BajaFred, correct me if I am wrong but I think your point is that the braking distances are similar to stock when rotors are not heated up.
Example would be in a panic stop on the freeway not giving you a much shorter stopping distance that OEM?
Truckzor:
I am heavy on the brakes off-road and on-road so the difference vs OEM is night at day for me. The OEM brakes are not bad but after just a few hard pumps at higher speeds it gets mushy and losses it's performance.
Hey brother - you're absolutely right. I worded my reply very carefully, and I'm disappointed in Truckzor.
Most people (wrongly, but I used to think the same, too) think BBKs magically help you stop shorter when the truth is you're limited by the grip of the tires. Both OEMs and BBKs can lock up the tires - it's up to tire vs ground friction at that point. Everyone overlooks this fact.
On the 1st panic stop, OEM (on a decent car i.e. OEM didn't ship cheap shit from the factory) and BBKs will stop within feet of each other. The video posted showed 136 OEM vs 125 Alcon on the 1st stop. If your BBK setup (plus new wheels & tires to fit larger brakes) weighs more than the OEM setup, you might actually see slightly longer stopping distance vs OEM.
I'm heavy on my brakes, too. Where BBKs shine is on repeated use and/or if needed, panic stops beyond the 1st one. OEMs will fade hard while BBKs will remain consistent.
I've done my own 70 to 0 tests with Baer, Brembo, etc over time and never saw "stopping power that can beat out super cars" like the other poster wrote - simply doesn't happen due to tires, not the brakes.
