Yes!, and in addition to the above, the best reason for two piece rotors is to prevent rotor distortion (cupping or bowing of the plate).
The stresses associated with a rotor’s friction area expanding from repeated localized rapid (or extreme) heat soaking fighting against the more dimensionally stable material in the more thermally isolated hat can (and does) cause one piece rotor material cracking ... which at speed results in sudden and violent unscheduled component disassembly events!
An interesting solution to this brake rotor stress warping phenomenon I first observed mounted on certain OEM BMW models (Z3M?) twenty years ago. They incorporate 8 or 10 ground steel dowel pins cast in a radial pattern between the separately cast friction plate and the hat, brilliant manufacturing idea, except that the whole assy must be replaced when the rotor is worn.
I’ve been using field serviceable, bolt-on, two piece rotors on my performance cars since the early 80s, converting up from the often whimpy OEM brakes to 12” Winston Cup series sourced parts for these heavy muscle cars.
As a machinist, I had to make my own caliper adaptor brackets, hats and spacers, hubs and modified spindles.
Today you can buy a bolt-on “Big-Brake Kit” for just about any car you might own!
The important bits, like the special 72 fin Martinsville rotor discs, 4X2” (or differential bore) AP, or JFZ monoblock calipers have always been readily available and reasonably affordable through racing parts supply houses.
On my 96 SS Impala I put (then current) Z06 fixed F-6 & R-4 pot mono block calipers with DBA Kangaroo Paw rotors @ all four corners, a huge improvement over the OEM 4-wheel disc junk, ~ (check out KORE3 brake kits!).
For my 2020 SRT DD, I bought Diversified Cryogenics’s Frozen Rotors, which are actually Akebono rotors cryo-soak treated for several days, they don’t look different after treatment but I can assure you these rotors are far more stable and resistant to wear, blotchy surface hardening (hot-spots) and plate warping. These cryo rotors perform better, and return a much extended lifespan compared to the same non-cryo-treated parts. I used to use EBC Yellow pads, but now I prefer Hawk HPS, or sd/hp+ pads for daily driving, great grip, low dust, easy on rotors.
The OEM Brembos, as you all know, make crazy dust and the rotor surface always looks dark, streaked, mottled and shredded, they don’t last very long under OEM Brembo pads.
