E36 M3 Front Splitter with Undertray

Short description:



Harrison Motorsports' Front Splitter with Undertray for BMW E36 M3

Our Harrison Motorsports front splitter with undertray is the perfect replacement for your BMW 3 Series E36’s destroyed factory undertray components. The one piece splitter will replace the factory plastic pieces that are inadequate and brittle. Most E36 BMWs are missing many, if not all of the factory pieces that comprise the frontunder tray. This leaves the engine components open to debris that may come in contact with your BMW‘s engine, oil pan and other vital parts.

Save on the cost of the splitter,  by picking the splitter up at our Alpharetta, GA location.  Available Monday thru Friday 9:30 AM to 6:00 PM.

This splitter will help to add front downforce resulting in better handling.   Drag is also reduced, resulting in better fuel economy. Spoiler supports are included as standard.  You may exclude them if you don't want them.

Harrison Motorsports BMW E36 M3 Undertray-Splitter

This splitter is manufactured from ABS (Acrylonitrile-Butadiene-Styrene) and is approximately 5.7 mm thick.  ABS is an engineering plastic that is easy to machine and fabricate. ABS is an ideal material for structural applications when impact resistance, strength, and stiffness are desired. It  has excellent dimensional stability and can be painted.  


  • Excellent impact resistance
  • Good machinability, easy to drill holes for mounting
  • Excellent aesthetic qualities
  • Good strength and stiffness, approximately 11mm thick
  • Order includes turnbuckles, also known as Spoiler Supports.
  • Requires OEM E36 M3 front bumper for installation.


Put that finishing touch on your BMW with this handsome undertray.  It will provide protection, performance, and peace of mind.

We recommend using the guide holes in the splitter as a template to drill holes in the bumper, and then bolting it to the bottom of your E36 M3 bumper cover.

Forward placement depends on what the sanctioning body you run with specifies.

We do not provide hardware, because people have their own preferred methods of attachment.
