RS-R Springs for Mazda2

[Camshaft]

Hey guys, I just noticed that these are available for our cars, and cheap, too: https://www.rs-r.com/product/mazda-2-superdown-sus-springs-2007-2/

I'll probably go with H&Rs, but has anyone tried these?

Looks like it drops the rear almost half an inch more than the front. Isn't this the same complaint some had of the Corksport springs?
