Compatibility with other chassis'

• 2007–2013 BMW E92 3‑Series Coupe (including 328i, 330i, 335i, M3 models)—all trims use identical mounting and fitment on standard or sports seats.
• The Left & Right part numbers above also interchange between E90 (sedan) and E93 (convertible) within the same model years due to shared rear seat structure.
• M3‑specific foam and trim variants (52100442129/52100442130) were rare; most CRT seats used standard bolsters.
