2. Baffled sump
Sump baffles are sections of metal (sometimes including swinging trapdoors), that are welded in to a car’s oil sump to help prevent oil surge during hard cornering. Their main job is to keep as much oil around the pick-up pipe, while not preventing returning oil from reaching this area. Baffled sumps can either be modified standard ones, or full aftermarket sump setups. Most performance car sumps have some form of built in baffles, but they can usually be improved, and most cars with known issues have off the shelf upgrades available.
