I didn't know I was arguing against you... I actually wasn't trying to argue at all. Guess I shouldn't have brought "feel" into it when I was attempting to emphasize the "know" part. They will feel better with fresh fluids. Pads, too. No shit? My point was the positive psychological component that comes from knowing you have "high performance" parts on your bike, when you probably can't use, at least on the street, any advantages they might offer. Kinda like when I put a slip-on muffler on my 85hp bike. Allegedly I gained maybe, <maybe> 5 hp at 11 or 12,000 RPM. The gain between 3 and 9,000 RPM, where I ride most of the time is neglible, but my bike sounds better, "feels" faster, and thus it <is> faster. My seat-of-the-pants dyno, connected to my brain dyno, tells me so. For my example I gained 5% hp. If I did 0-60 in 4 seconds before, I should be 5% faster, or 2/10 of a second. Can I tell the difference between 3.8 and 4 seconds without a stopwatch? No, but it felt faster. I am not a brake line expert. I have no idea if SS is better than rubber. Seems to me it should be. Could I feel the difference? I doubt it. Can the experienced trackday guy, who's riding at 90% plus all day long feel it? I'll bet (s)he can.
