We are very excited to release the new Speed Engineering Directional Vented Rotors:
http://www.scienceofspeed.com/produc.../brake_rotors/

Two piece rotor technology at a one piece rotor price: The Speed Engineering rotor surpasses the performance of any other single piece rotor for S2000.
Factory style rotors, and all other aftermarket one piece rotors currently available for the S2000, use non-directional radial or straight vanes (see diagram below). This is ideal for cost savings as only one casting is required for either left or right rotors (the rotor can be mounted on either the left or right of the car). Directionally vaned rotors are much more of an effective design for thermal dissipation as air flow is actively pumped from the center to the outside of the rotor. This active pumping of air can decrease rotor temperatures by more than 100 degrees F dramatically improving brake rotor and pad durability and life as well as improving fade resistance on the track.

This design requires two separate castings for either left or right for a one piece rotor - usually making the approach not cost effective. Despite this, the Speed Engineering rotors are priced aggressively and similar in price to standard non-directional vaned rotors.



The Speed Engineering Directional Vented Rotors feature vanes that are directionally oriented for both the left and the right rotor to allow air flow to be pump from the inside out. The center reverse mounted hub of the brake rotor allows the most air to enter and be sucked through the disc under vacuum.



Time Trial and Spec Class S2000s Rejoice! - A competitive advantage while improving brake durability and decreasing cost to track your car.
The cooler running rotor will allow more consistent brake performance, increased durability, and a longer use life. Especially important to Time Trial and other "spec class" S2000s, this rotor is factory sized and not 2 piece, so no additional class points deductions required.

Each rotor has a top quality Dacromet surface coating. Unlike simple paint applications used by aftermarket manfactures, the Dacromet coating is far advanced offering superior general corrosion, bimetallic corrosion resistance, and solvent (such as brake fluid) resistance keeping your rotors looking fresh. Each rotor has a fine cross hatch machined for easy brake pad bed-in, and feature a unique J hook slot design to offer outgassing and sweeping of material from the brake pads

Rear rotors are available in the same factory solid design (non vented with matching J hook slots as the front rotors).

Can you get the center hum portion in black?

i also notices that inner circle vans openings (close to the hub) are on the outer side of the rotor vs inner side on the OEM.

Bummed I already installed some Powerslots a couple months ago.

do they have a 2-piece floating for our cars?

ScienceofSpeed

Sorry, they only come silver - which is from the high quality Dacromet plating which is superior to painting. These could easily be painted black if you'd like.

That's correct, this is a reverse mount disc.

Not currently, but it is something we are exploring. The 2 piece rotor will be significantly more expensive. The center hub makes up a very small fraction of the weight of the disc. When you factor this in and the weight of the fasteners to fasten the hub and the disc ring together, the advantage of a 2 piece rotor is very minimal since these rotors are already directional.

Hey I have a question about these...seems as though they are the same as the APM rotors that Evasive and Horsepower Freaks sell? If so, that's fine, I am just wondering because the look is similar, price is similar, and they both seem to have the Dacromat coating. In any case, I am pretty much ready to buy, quote me shipped price to 22181?
