With all due respect to Stoptech, their numbers should be close to the math - if not, then something is not right. Sometimes the information gets altered as it transfers from engineers to marketing people. I've had that happen far too often in my professional life to just accept numbers when they don't align with basic math and physics. Again, if you don't mind, please review the math in my spreadsheet and if there's an error, I'm happy to fix it.
FYI, I'll leave it to others to call if they choose. I already have a BBK
Are you taking piston sizing into account, or....?
When I received my kit, I got black anodized rotor hats. I was just wondering if my hats we're the same part number as yours. Also do your rotor hats have the aero fins for additional cooling? Mine are just blocks and do not have the cooling fins.
Here is a good pic of what the cooling fins look like on stoptech rotor hats.
i am sorry for the nob question but could someone explain this kit vs st40?pros vs cons . if someone is buying a kit you should definitely step up to stc43 vs st40?
Did stoptech indicate why they moved away from the aero/vaned rotor?
based on the purchasing experience of a miata friend of mine, you have a choice between the aero rotor and the pillar rotor. In ND miata size, the pillar rotor is 3lb lighter per rotor and stoptech said they only saw an 11% difference in circle track racing... So a stockish power s2k is is prolly fine with the pillar rotor, if you have boost the aero rotor might be worth the upgrade. you also have the option for a sprung floating rotor or full race style no tension spring floating rotor
