The original oil cooler used Tube and Fin construction. While this is acceptable for cooling performance, it is not a very robust design. CSF chose to go with a Bar and Plate construction to improve durability. While there is plenty of ground clearance, the cooler is low enough to see some potential abuse on the track. CSF wanted to offer that extra durability of a Bar and Plate cooler for track enthusiasts and those running their car on the lower side.
