Stainless Steel has poor thermal conductivity (Titanium is worse, i think), so would have difficulty dissipating the heat. However, I believe S/S is used on motor cycles. Race cars use carbon composite disks and pads.
Brake disc materials have to meet an SAE standard. This makes it hard to see how aftermarket disks would be inferior to OE discs, unless the OE discs in some way exceed the SAE standard.:

"Disc brake rotors are commonly manufactured out of a material called grey iron. The SAE maintains a specification for the manufacture of grey iron for various applications. For normal car and light truck applications, the SAE specification is J431 G3000 (superseded to G10). This specification dictates the correct range of hardness, chemical composition, tensile strength, and other properties that are necessary for the intended use"¹.
