Flywheels, Superchargers and Clutches Mazda-specific,Oh My!

I just read an update on the CarTown-EX faceBook fan page confirming
Mazda Upgrades are here! Being a Mazda Fanatic myself it's nice to find Mazda-specific Flywheels, Superchargers and Clutches.
The following Upgrades have been added to Upgrade Mystery Boxes and Workbay job drops in CarTown EX:
* Mazda Premium Flywheel
* Mazda Racing Flywheel
* Mazda Premium Supercharger
* Mazda Racing Supercharger
* Mazda Premium Clutch
* Mazda Racing Clutch

All Upgrades are Mazda-specific.
