Just to add some clarification on terminology to prevent confusion:

'West Coast Drive' is a term used to describe the type of drive train pioneered by 60 and 254 in the early 2000's (2004, if memory serves me). It's distinguishing features are rectangular tube construction, live axle setup and cantilevered wheels. Almost all WCD's have a dropped center to aid in turning (only notable exception was 2009 - the lower COF between the wheels and floor negated the need for a dropped center in most applications).

That being said, a dropped center drive train isn't always a WCD. Referring to all dropped center drives as WCD may lead to some confusion.

Also, on the same line of thought, 'Tank Drive' really refers to a type of steering and not a specific type of drive train. Technically, 95% or more of the Robots in FRC are Tank Drive, meaning that they don't have any sort of active steering - the two most common types of live steering in FRC are Car Style Steering (Front and/or rear wheels mimic those on a car) and Swerve Drive style steering - so referring to a drive as a tank drive isn't really all that specific. When discussing drive trains it helps to refer to them by wheel configuration since it reflects the performance of the drive much better, for instance, 4WD Tank, is very specific and easy to understand and visualize - anyone familiar with basic drive trains should be able to predict the performance of the drive if they're also given the wheel type.
