OEM lowering springs

2014 Mazda 2 GX
Anybody have any experience with the OEM lowering springs?

In the market for some springs and the idea of a manufacturer supported part on a car with factory warranty remaining is certainly attractive (not that I'm anticipating issues if I go aftermarket, but it's one less variable).

MSRP: $399.95 CAD
Part #: 4100-77-777B


Lowers vehicle by approx. 30mm (1.2")
