Find Your Perfect Spoiler

It really comes down to how aggressive you want the rear end to look.

PSM Style, V-Style / M4-Style and CS Style spoilers compared
Top: PSM Style · Middle: V-Style / M4-Style · Bottom: CS Style
  • CS StyleThe cleanest and most subtle of the three — an OEM+ look that adds just enough to pull the rear end together without doing too much.
  • V-Style (M4-Style) This spoilerThe sweet spot in the middle. A noticeably more aggressive shape while still looking balanced and not overdone.
  • PSM StyleThe most aggressive. The biggest kick, sitting higher off the trunk for a much sharper rear presence.
