is anyone running either the stoptech aerorotor or the EBC gold 2 piece rotors from Motech performance? Im in need of new rotors in the front and figured i might aswell upgrade to a 2 piece rotor so paying for rings will be cheaper in the future.

FYI Aerorotor rings are about $350 each plus you need to buy a new set of mounting hardware each time. If I were you I'd just go the FCP Euro route with OE/OEM rotors. Unless you're tracking a lot there's really not much benefit to justify the cost increase.

I went with the Aerorotors on my F31, and they do hold up very well, and definitely cool better on than the stock rotors on the track, but going the FCP + free exchanges route will be cheaper over the long haul. One nice thing about the Aerorotors is Stoptech rates them for 2mm wear instead of BMW's typical 1.6mm.

so if i buy a set of rotors from FCP i can just send back my oem ones and get my money back or how does that work?

The first set of rotors you buy from FCP as you would any other store.

The second set (and all sets going forward) of rotors you buy from FCP, you send the first ones back that you purchased from them, and then they'll refund your purchase price on the 2nd/last set purchased.

The hardware kit comes with the rotor ring so no need to spend extra for it.

Stoptech has PNs for both just friction ring alone, as well as friction ring with new HW. Their PNs, along with most retailers' descriptions really don't tell you what you get.

Even when I asked Stoptech CS what the PN for the replacement ring for my disc was, they initially only gave me the one that didn't include HW.

That must be something new.

We have always sold rings with hardware included. Will look into the new part numbers without the hardware.

The replacement disc PNs are below for the F2x/F3x 370mm slotted rotor ARK (PNs 129.34144.13 and 129.34144.14) that I have.

Replacement slotted discs without HW:
30.B39.1111.01
30.B39.1112.01

Replacement slotted discs with HW:
30.B39.1111.99
30.B39.1112.99

This is of 4/2019 (when I asked Stoptech). The kits with hardware cost about $65/each more than those without.

can someone link me to where i can read up on Stoptech 2-piece rotors for M2C?

don't need them yet but want to go this route when the time comes. Have had the tophy kit on my E90M3 and it's been incredible.
