aren't all brake mods a free point mod in virtually every series? I thought it was, which is why I ordered StopTechs... [confused now]
yeah, my fault... forgot about SCCA classes... =/

For people that have gone the distance of routing ducting, that ducting will be useless on these bad boys.
I wouldn't say the ducting would become useless, maybe less efficient but any air to help cool the brakes will still help.
Ducting will still help with a directionally vented rotor. I'm not sure how these would make it less efficient.

Centric rotors are $25.00 ea? Regardless, the rotor life is only one benefit. The benefits of a rotor running cooler including pad life, ball joint life, fluid boil, and fade resistance.

Take a look at a stock rotor and then take a look at the rotor you're selling and you just might see why I made that statement.

No but cteks are, centrics are roughly 45-50 bucks

You're forgetting bearing life.

I think I understand your question better. The front rotors are reverse mount. This is done because it is more efficient for the suction created by the vanes to draw from the front side of the rotor than the rear. This photo shows the rotor installed on the front upright.



However, ducting to the center of the hub area is still utilized by windows in the hub barrel that feed the vented rotor disc as shown by these photos.



In addition to the disc being more efficiently fed on the front side with the reverse mount design, I believe that this method is actually more efficient for ducting to the hub area as well compared to a factory style rotor with a rear mounted disc. The reverse mount design causes air to be encapsulated by the cup of the hub barrel feeding the entire rotor all the time (where there is suction present in all vanes). This will be more efficent than ducting only a portion of a factory rotor on the back side, where there is no suction anyway from the staight vanes.








Hope that clarifies the design.

I think that these rotors are well worth the extra $50.00. Not only in performance and cost savings of the brake parts themselves, but other related components, including the wheel bearings that you mention.

For SOS and a good thorough explanation. I will be looking to pick up a set of these for next season.

Ordered a set from SOS this week and they shipped same day and sent tracking info. Just the type of service I'm used to from them.
