EB Werks 2- Piece Rotor - Review

Drifting
Here are 2,000 kilometers added this past weekend of coast pure hwy 1 driving & twisty fun roads along the way. Brings me to a close to 10k miles on street plus those track days. IMO either the wrong stuff was ordered initially from the get go (rotor casting, thickness, vains, slots etc. / or their formula has changed.
Pads are pfc01s. Pretty harsh pads

The AP J-hook rotors I used were actually Nissan GTR 380x34mm rotors. Toughest rotors I ever used. I ran them for a better part of 2013 on my car and then swapped them over to my friends 7GT3 where they have been ever since still going strong after several sets of PFC 08s. The rings alone were $1100 for the pair so by no means cheap but considering how long they have lasted so far, they have been a great value.

They are full depth 65mm rotors which accept the standard large pfc0991/pagid2707 standard pad shape. You CAN NOT use the regular 6pot calipers (normally used on 350 rotors) with the 380mm rotors due to the fact that those calipers will not space out radially because of their offset mount. As you try to add spacers, the bottom of the caliper will impact the larger rotor because the caliper moves away from the rotor at an angle as opposed to 90 degrees with respect to the centerline of the rotor. You must use the 380 caliper with the 380 rotors.

Interesting, I always thought the calipers are radially mounted, that's why Alcon does 360mm rotor for the 996 GT2/3 to be used with 5mm spacers. Or it is that 5mm is not big enough difference compared to the 15mm?

996 GT 350mm caliper mounting...
Nice discs BTW, might be what I try next

Got it. Thanks for the info. Guess 360mm rotor is the largest that can be used without going for a different caliper!
Does the 997 caliper have the same bolt spacing to be a direct bolt-on?

The 996 calipers have a 146mm bolt spacing. The 997 380 caliper has a 225mm bolt spacing. You must use the OEM Porsche/Brembo adapter to bolt the 380 caliper to the 996GT2/3/Cup upright. If doing the conversion, you would also need to install the larger 997 rear calipers to maintain the proper brake bias. The 996GT2/3 caliper is too small. Finally, you would need to install a 997GT3 brake master cylinder to firm up the pedal. A 997GT3 vacuum pump is a good addition to improve pedal feel (996 cars only use throttle body vacuum).

Great thread and info all!
Explains a lot to me as I am just getting to know exactly what is on my car ....
Just re-checked per the posts below and in fact the rotors are 350mm so powdrhound's suspicions were correct and they are the OEM 996 rear calipers. In case anyone wants data for the shimming needed for 350mm rear rotors see below:
I just finished replacing all my wheel studs which necessitated getting to the hub. As a data point the shim length used on the rear calipers was exactly 11.85mm square (ie all four) and that puts the pad perfectly top/bottom of the rotor FWTW.

Explains a lot to me as I am just getting to know exactly what is on my car - in this case the 997 calipers and 380mm rear discs per powdrhound's excellent info, i think. The rear pad shape is Pagid 2405. Sound right (if anyone happens to know)?

You are correct; unfortunately tried to post from memory and do not have my info here to verify (hence the edit :-) ... Have the measurements and will double check when I get home. ... rechecked and revised post above ...
Thanks for the info!

The 380mm calliper has a different bolt space to the 350mm calliper - Porsche do have an adapter available that allows the swap to the 380mm calliper.

care to share the part number for adaptors?
