G80 M3 GLOSS BLACK HIGH KICK TRUNK SPOILER

Performance aesthetic to match the performance-oriented G20!
 
The G20 is a great example of a wolf in sheep's clothing. These models pack performance under the hood, have a comfortable but sporty suspension, and have a feature-rich interior however from the outside of the vehicle you would never know. At ECS we own a G20 M340i and this is one of the best vehicles we have had the pleasure of driving. What our M340 lacks in appearance is made up by its comfort, technology, and definitely performance.

Though we are more than happy with the vehicle's drivability we felt that people should know the G20 is a performance-oriented model! After a lengthy process of scanning, design, and testing we came up with a trunk spoiler spoiler that compliments the factory body lines yet completely transforms the look of the vehicle to properly represent the performance attributes of the 3 series. 

Upgrade to performance-focused styling on your G20 with the ECS Tuning Gloss Black Trunk Spoiler.  This trunk spoiler was engineered in-house and designed to follow the curves and lines of the body to offer a more aggressive look that matches the factory appeal of the vehicle. The spoiler is crafted of a durable UV-stabilized ABS polymer to achieve its deep high gloss shine and provides a sporty style that's sure to set your vehicle apart from the rest. Installs with no drilling, cutting, or modification of any kind required. After you have everything lined up and the surface clean of any contaminants, simply remove the liner on the already attached high-strength dual-sided tape and press the spoiler firmly onto the trunk lid.  Install the spoiler as-is or with proper surface prep, this spoiler can be painted to any color you like!

G80 G82 REAR DIFFUSER - GLOSS BLACK

Take your time to indulge in the BEST ABS diffuser we have seen on the market. We are so excited to offer this great addition from Turner Motorsport, they absolutely knocked it out of the park. The fit, finish and styling is like no other diffuser on the market. 

Upgrade the exterior styling on your G80/G82 with the Turner In-House designed and engineered ABS Rear Diffuser. Utilizing factory mounting locations and supplied hardware this diffuser is a direct bolt-on upgrade that can be installed directly in place of your factory diffuser. Featuring a deep profile, an aggressive fin design, this exclusive design from Turner Motorsport will be sure to turn heads! 

Pay close attention to the design characteristics of the diffuser. The emphasized outline of the diffuser adds a whole new dimension to the rear bumper bringing out the beautiful body lines of the G80. By adding an aggressive fin design and boxing around the exhaust exits the rear/side view is almost transformed into a whole new sub model that BMW forgot to offer.

Features & Specifications:

  • Designed to accentuate the G80/G82 body lines
  • Perfectly houses quad 4.0" exhaust tips for upgraded and factory exhausts
  • Designed in-house using state of the art 3d laser scanning and CAD technology for precision fitment 
  • Mounts to existing bumper insert mounting locations with supplied hardware
  • Made from lightweight, vacuum-formed ABS polymer, with UV-stabilized gloss black sheet 
  • Mimics the lower section of the bumper with added character to amplify OEM features
