I js ordered a set of swift springs.i liked that it has a mild drop not to crazy.I have a 2011 g37 ipl
sitting on 20" inch wheels
tire specs
front 255/35/20
Rear 285/30/20

Will I need to also get camber kit for front/rear for a mild drop w the spring.

 

I'd at least get the rear arm & toe kit, but the complete F&R set would be what I would recommend, your tires will thank you
