need some confirmation pls, thx.

just purchased some new rotors. stoptech's new ones for the is350: 128.44138CL/128.44137CR.

44138 is left, 44137 is right. the stickers and the boxes and even the engraved part number on the side of the rotor all say this is correct. even went on centric's webpage to confirm the part numbers with proper orientation.

however, upon closer inspection, the internal veins seem backwards. not the cross drilled patterns on the "visual" outside, but those between the rotors.

i've included the following picture. visually, this should be the right rotor. however, part number/sticker say it's left side. probably gonna call stoptech's tech department tomorrow to double check, but wanted to make sure i'm not the only crazy one. i've installed plenty of rotors b4, and this one seems odd.

If you are installing the driver's side front rotors and are looking at the hub, the internal veins of the rotor should face this way (/////), not forward (\\\\\\).

Just wanted to comment on the labeling.
I too, got a set of mislabeled front slotted StopTechs - same part numbers stated in the start of this thread. Rotor deemed LEFT, which would've been Drivers side, when set proper for the internal vents...went on the RIGHT sides front hub. Same on the opposite side...Right labeled rotor, went correctly on the Left side. The REARS I also installed, are not directionals...but yeah - both sets were made in Feb' of 2013, so someone - recently - is smoking the goodies in the labeling room.
Whats up StopTech? I was perplexed for a few minutes scratching my head wondering what the deal was...had to stop and come inside to scope online and assure myself all was good.
So your not alone homie...

BUT - all lameness aside - I do LOVE! my new rotors and the Red Stuff EBCs I put on there with em. Not that the stock stuffs on my IS350 didn't work or anything, factory gear was soooolllliid...these just feel right! Every single time I touch em....so nice

They're not mislabeled, they're actually following Lexus's design. I had the same questions about my slotted rotors and all of the details I found out from them I posted here :
