Nevertheless, I did a few hard braking exercises and given they are still being bedded in it's hard to say conclusively if they are better than stock in various aspects. The initial bite does seem to be very good though, pedal depression seems shorter than stock if that makes sense, sounds strange but I get that sensation (as I was saying in my build thread its almost as if the brake pedal sits a bit lower now OR doesn't depress as much as it did previously). Will need to spend more time with them and I'll definitely come back to you with how they are doing.
I noticed that the x385 and x386 have a production date of up to 01/2010 listed next to them, whereas the x801 and x802 don't have a date at all. The latter are also more expensive by $20 each, so maybe there is something different about them. I'd love to find out definitively what those differences are.

At any rate, do let me know how you end up liking those brakes. I may try to sweet talk my dealership into swapping out my stock pads and rotors for these ones when it comes time to replace them under warranty.
