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 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 slotted non-directional vaned rotors. |

| advantages of Speed
Engineering Directionally Vaned Rotors: |
-
improved cooling efficiency - compared to factory &
aftermarket straight vanes, directional vaned rotors improves
durability of brake components, suspension & steering joints.
- J hook slots allow out gas &
sweeping of material from pads.
-
Lighter weight design -
front rotor ~1 lb lighter than factory
- Dacromet coating -
coating on non swept areas (hub & vanes) inhibit corrosion to keep
rotors looking great.
- double disc ground - taper
free finish ensures parallel surface and better brake pad - rotor
break in.
-
mill balanced -
additional machining operation eliminates rotor vibration.

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. In addition, the rotors feature a "reverse mount"
design that places the ventilation on the wheel side of the rotor for
increased air flow. The reverse mount design allows the factory heat
shield to be retained in order to protect the suspension and steering
joints from heat,
The cooler running rotor will allow more
consistent brake performance, increased durability, and a longer use
life. In addition to increased durability from the rotor - suspension
joints, steering joints, and wheel bearings will benefit from cooler
running rotors.
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 on the rotor hub
and in the vanes. Unlike simple
paint applications used by aftermarket manufactures, 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). |
