I'm getting Vogtlands with KYB GR-2's. On gen 5 maximas despite the fact that they are OEM replacements the GR2's work fine even with a 1.4 drop. They survive winters without freezing, there haven't been bumpstop issues, they soften up a bit after a few months creating a pretty comfy ride... and the combo only costs like $400.
Oh and your spoiler situation... what, um, does the stock max spoiler really underperform at highway speeds? ... like an 80mph lane change with an empty car with 1/8th of a tank of gas. If so, then yeah, what would be more functional without looking, uhh, just dumb?
