STRDAL. There is only one Aero kit for the West Coast. It consists of a pair of front splitter extensions. These fit beautifully.
A pair of front and rear cill extensions. These do work well. After only a short (DNA to home ) jurney the front one especially is covered in road dirt but the cill under the door and running back to the rear brake ducts were very much cleaner than before.
The rear wing is quite small. With the rear of the car being so high visibility in the mirror is limited anyway so the height of the wing was kept down and is only just visible in the mirror. Remember the West Coast is a GT not a sports car so doesn't need so many aerodynamic aids. Then SL as standard can pull .95G in bends, that's more than I can handle.
As for what people are calling their cars, that's up to them. Hamann seems to be the popular choice but you could call it a Novitec or a Khan, the choice is yours. I don't have the wheels that look like those from any of the tunning companies so I just call mine a West Coast Aero.p
