Default One piece rotors an option for Brembo GT fronts? 355x32mm

EDIT: Stop Tech just told me I am SOL for finding any one piece rotors for my Brembo Gran Turismos. Is this true? Am I really looking at a minimum of $350 each for rotor rings plus $100 in new mounting hardware for each side (Stop Tech brand)??
If so, what are the Stop Tech numbers (R&L) so I can shop around? Cheaper options??

I will do floating ring replacement ONLY if no other option. Right now I desperately need a reasonably priced alternative.
Still can not get thru to Zeckhausen. They have not returned my calls.


I have a 2009 BBK from TMS. It is full a full kit(all four courners)
Brembo GT Gran Turismo with 6 pot monobloc calipers front and 355x32mm FLOATING ROTORS
Rear: Brembo GT Gran Turismo with 4 pot calipers and 345x 28mm
Just need two fronts. Left side ASAP. Rears OK for now.

Zeckhausen is busy and has not called me back.
I need just the front rotors. My original floating rotors are severely worn. I have fresh pads, but can not afford $800+ to replace my rotors with the same floating ones.
Looking to spend a tiny fraction of that for ONE PIECE rotors that will fit. same 355x32mm dimensions, but the hat must fit my car.

So far I have found:
1) Centric Premium cross-drilled front rotor 355x32mm $104 each +$30 shipping
https://www.zeckhausen.com/catalog/p...ducts_id=10703
fitment unkown


2)StopTech (128.20020) Premium Brake Rotor $83 each shipped PRIME(I assume) does not specify right or left. Fitment unknown



3)StopTech 126.20020SL Sport Slotted Brake Rotor; Front Left (only) $132.83 free (slow) shipping

Go back to stock until you can afford new rotors...

Coleman racing wil make a direct replacement for you for around $240 each. Either tell them exact specs or ship your worn rotors

I hear people using Stop Tech Areo rotors as direct fit to Brembo Top hats. Stop Tech guy said so. Can anyone confirm?

Stop Tech rotor ring slotted left: 31.737.1101.99
$345 with mounting hardware plus shipping
https://www.zeckhausen.com/catalog/p...products_id=55

Stop Tech same ring 31.737.1101.99 slotted left free shipping but no mention of hardware $320.15 (see below. I believe they automatically come with hardware)



CHEAPEST price is CENTRIC using exact same part number. Centric and Stop Tech are the same company.

Centric 31.737.1101.99 Brake Rotor (AERO-ROTOR + HDWR - 355x32 SLOT LEFT) $306.90
Going to check if hardware is included. I can, but prefer not to reuse my old rusty Brembo mounting hardware. I have ft lbs and Loctite directions.


StopTech AeroRotors comes with hat mounting kits, consisting of: Drive pins, M5x0.8mm socket head cap screws (4mm Allen head), and Inconel (Nickel alloy) Belleville washers, acting as anti-rattle springs. Also included is a single use packet of medium-strength, wicking grade threadlocker, and an instruction sheet.

They do fit without issue.

That said, I did it once and won't be doing it again-- they lasted 1/3-1/2 as long as the brembo rotors. So, cheaper up front, but more expensive/mile and more PITA/mile than the OE brembo rotors.

You should replace the hardware, whatever rings you go with. Hat can be reused without issue.

Thats what they say. Going to call Stop Tech and confirm if their Centric brand (same number.same thing....I think) also came with hardware.
I will replace next year with real Brembo when I will have much less financial constraints. According to Obioban the Stop Techs dont last as long. My Brembos lasted about 15K miles in the street with very very aggressive track sessions and racing pads on the track AND on the street.

I have zero track sessions planned. I can do my commute to work barely using my brakes because I work the night shift. I will be OK with Centric/Stop Tech for the next year. I just cant swing the extra $200 PER rotor for the Brembos.

Run street pads on the street! Will quadruple your rotor life.
