In May of 2011, we installed one of the first sets of Speed Engineering directional vane rotors for the Honda S2000. We conducted testing using onboard datalogging equipment between straight vaned factory rotors and the Speed rotors. The testing demonstrated the directionally vaned rotors, which are more efficient in cooling due to the pumping effect of air through the rotor, were able to shed heat faster and trend cooler than the straight vaned factory or other aftermarket rotors. The directional vane rotors ran an average of nearly 60 deg F cooler and nearly 100 deg F cooler over a 22 turn lap. The question then became - what is the long term durability of these rotors?


A half year later in February of 2012, we posted a long term update after 17 days of track use (click here for more). We're now posting an even longer term update. The car has now seen an impressive 17 days of track use with the same set of front and rear rotors!

The last day included running with an increased power of 350 wheel horsepower resulting in even higher braking zone entry speeds putting the rotors to the test. In comparison, the set of factory rotors on the car lasted only 5 track days before complete failure (crack running through the rotor). Only after 13 days of track use are we starting to see heat fractures forming on the surface (see photos below) - this is quite an improvement over the durability of the factory rotors. We are very happy to report the success of the rotors in our long term test has truly cemented our confidence in the rotors ability to not only produce more consistent braking performance - but also long term value in being able to last much longer than conventional rotors. When you factor in that the front pair of rotors costs only about $50.00 more than a conventional straight vane slotted rotor (ie. Power Slot) - the choice is clear.

Are these still available? No more J-hook design in the rotor?

ScienceofSpeed

Yes, they are in stock and ready to ship.

We are using the straight shots as shown in the first photo.
