Here is a sneak peak at Ridgeline Motorsport's upcoming GT4+ Carbon Fiber Aero Kit for the F8X M3/M4. 

The new GT4+ Splitter has a number of key features:

  • Their innovative RM Spec foam core composite thermoplastic splitter with molded in tunnels just as strong and light as infused carbon, at only ⅓ the cost.
  • Molded tunnel and air escape channel design (unlike other brands’ bolt in tunnels and oil cooler cutouts, which completely disrupt splitter airflow).
  • The splitter will be paired with their infused carbon lip, which serves purely as an air dam and aesthetic piece.

Their new GT4+ Wing addresses three key issues found on the OEM GT4 wing when used on the street:

  • The OE hinge mount trunk slot design can leak water in rainy weather.
  • The wing height is limited by GT4 class rules, making it less than optimal.
  • Fitment is restricted — the OE wing only fits the F82 and not the F80 without further modification.

Ridgeline Motorsport redesigned the wing risers and endplates to better match the OEM GT4 style, creating a more Touring GT Race Car look overall.
