A few questions for Chris/SOS
Do the "j" dimples accelerate pad wear as much as some slotted rotors? Do they serve any functional purpose? Are they casted in? I'm actually very interested in the product, since I'm gonna need a new set of rotors for a track event that's coming up very soon.

Will you guys be offering the rotors w/o the dimples?
Thanks

Diet Plan.
Chris, just as a heads up.. we'll be testing a couple of these and more than likely Mac will share the results. We have guys that don't last 1 trackday with their rotors (other issues, we know).

No, my questions were not related to race class qualifications. I was concerned with possibly unnecessary pad wear + lost of contact surface area in order to machine in the hooks.
I wasn't aware of the advantages of the j slot so I searched around online. From reading AP's website, it appears that the hooks are designed to improve initial bite over standard straight/arched slots which should already improve initial bite over oem blanks. Also found that some of the subaru guys have track tested this style of rotor, albeit a different brand, and noted that the disc temperatures were noticeably below that of their stock blanks. It seems that the dual/front venting works, but I'm not exactly convinced the J hooks are needed. They do look nice, and SOS does have competitive pricing for this style of rotors for the s2k.
Hopefully we'll have more data available to us soon.

I was one of the Subaru testers back when I had my STI. They were APM Racing rotors which I also have on the s2k but seem like they are now exclusive through SoS.
