Argh... long story short, I've ended up going for the Advan Neova AD08 R's.
Now for the part I'm unsure of -- and yes, I should have checked this before ordering...
Should there be any issues with running 295/30/19 in rear, stock Rays, 25mm spacers on swift springs and about -2.38* rear camber.
I'm pretty sure that will work, but confirmation would be greatly appreciated
