what's the difference between
Csl elite racing wheel ; csl elite wheel base ; csl elite wheel base +
Should be pretty much completely explained in the webshop descriptions.
CSL Elite racing wheel is a bundle with a CSL P1 wheel and a CSL Elite Wheel base +.
CSL Elite Wheel base 1.1 is a replacement of the old v1 with the mosaic front with same motor as CSL Elite Wheel base+ and CSW V2.5.
CSL Elite Wheel base + is the most advanced CSL Base you can get with different electronics than the v1.1, therefore fully Fanalab compatible and with ps4 compatibility.
CSL Elite Racing wheel consists of the PS4 version of CSL Elite steering wheel and CSL Elite wheel base + . In other words CSL Elite Racing wheel and CSL Elite wheel base + have identical wheel bases, but CSL Elite Racing wheel comes with steering wheel. Both are compatible with PS4.
There are two others CSL Elite wheel bases:
CSL Elite wheel base V1.1
CSL Elite wheel base (discontinued)
These two wheel bases are not compatible with PS4.
