While the rotors are not part of the hydraulic system, their effective diameter IS taken into account when calculating the proper piston sizes. When a larger rotor diameter (acting as a lever arm) is used, often times slightly less overall piston area is required to make adequate torque at that wheel. So while the rotors are not hydraulically actuated, their size does have a small effect on the design of the hydraulic components. |

Thanks for the info on what actually is basic knowledge and something I should have known (and which I learned in principle 20 years ago in engineering school...) |

So I was able to obtain a set of these with the nickel plated option. They look fantastic and brake feel so far is very confidence inspiring. Haven't had a chance to take them on track yet.

The kit looks awesome in the nickel plate on your M3

They look great, looking forward to review once you get back from the track.

Replacement rotors for front and rear (and associated hardware for attaching to hat) are available? Cost for these?
Someone asked for weights awhile ago and I don't think that was every published. Are the Sparta brakes/rotor combo lighter than stock or heavier? |

OEM Calipers Front Caliper- 10.65lbs ea. Rear Caliper - 8lbs ea. OEM Rotors Front Rotor - 24.4 lbs ea. Rear Rotor - 20.4 lbs ea. Sparta Calipers Front 6 piston Caliper: 10lbs 1.8oz Rear 4 piston Caliper: 7lbs 8oz Sparta Rotors Front Rotor 380x34: 26 lbs Rear Rotor 380x34: 23.5 lbs OEM rotor size F: 380x30 R: 370x24 The real difference is in the thermal capacity of the rotors and calipers. Rotors are larger in thickness F&R and larger diameter in the rear, than OEM. This shows the difference in increased rotor weights. In addition to that, the F8x rotors are already "2 Piece", making it harder to reduce weight over something like that of a E9x one piece rotor. Pricing includes hardware Front Rings (pair): $970 Rear Rings (pair): $945 Let me know if you have any further questions.

Here are some pics of the bridge. Hopefully not too small.

Not really sure, maybe I can reach the bolt head with a 1/4 8mm 12 point socket but I don’t have one on hand.
