anyone out there with the 350z tein h-tech's out there running 20s? pics would be great...wondering if this would be a good enough drop to get rid of some of that wheel gap. thanks in advance

Not enough.

^ exactly what I was gonna say..

I have 350z H-Tech drop, it's a noticeable but pretty lame drop. Should've gone with S-Techs instead; don't make the same mistake as me, do it right the first time.
