Z1 2-Piece Rotors and Carbotech 1521 Pads

Super Werty

Whats wrong with the initial warm up occurring slightly faster, if the max temp is ultimately slightly lowered?

THAT would be ok. But baits are used to slow you down. Slow down, less air, hotter.
More meat means that if a disc is 400 degrees, you hit the brakes, heat them to 500. Less meat means you heated them to 550, yeah, it will cool faster, but 550 May have already killed you're pads and fluid.


All that being said, I LOVE my Z1 rotors. Definitely can feel the performance

I see your point but on the flip side of that the Z1 rotor may not be at 400 initially. Maybe it's at 375 and goes up to 490...bigger jump in temp but still lower than stock and then cools back down faster than stock.

lol, truth is we dont know. but I love the rotors

rotors look sweet man...I'll wait for the rears to become available before I pick up a set.

I see both views. What I get told all the time by hard core track guys is that they go to a BBK not for extra stopping power, more for extra meat. Because they can get maybe 10 track days on OEM rotors, but since the BBKs have more meat they take more heat and may last 20 at best

Damn I'd hope the OEM 14x1.25" is enough meat! I mean that is a big brake kit on other cars. To me it will come down to cost. I've never priced a OEM rotor but I know the outer rings are like $275 each?? So I guess just how fast both get chewed up by me is the question. Money aside I'd still do Z1's or something for the lighter weight hoping my lap times are faster vs OEM even if the OEM brakes later in the corners.

well what meat are they talking about? Surface area of the rotor I would assume..not the thickness of the rotor

Im curious now how the thickness compares to lets say...the Stoptech bbk

just browsing around and found this....http://www.myg37.com/forums/attachme...it-photo-1.jpg

just guessing but width looks very similar to the z1 two piece

But is it? Its a chicken or the egg come first kind of thing. More metal means in turn 1 from say 140mph down to 40 you heat a thicker rotor to xxx while a less material rotor goes higher. Now onto turn 2 the more airy less material rotor is cooling faster but it started at a higher temp in the first place. Now only turn 3 will show the winner as one will be hotter and will have more fade which means you need to brake later ultimately. Tracks will also differ a winner depending on braking zones etc. like a bike with sprockets, one setup doesn't work everywhere.
