Disclaimer
aerofabb, LLC is not responsible for any damage to you or your vehicle while following this Install Guide and/or installing aerofabb products. Professional installation is recommended. aerofabb also encourages you to read through this Install Guide in its entirety, ensuring all parts and hardware are present before beginning the actual installation process. Warning – Hardware Thread Galling/Thread Lock
We provide fasteners in stainless steel to ensure a long lifespan. Although stainless steel has many benefits like extreme corrosion resistance, threads can be sensitive to nylon lock nuts. We recommend installing hardware with an Anti-Seize thread lubricant to prevent thread galling. Slowing down the speed of installation and keeping bolts stationary while tightening nuts are common practices to prevent thread galling.We also recommend installing hardware with hand tools to prevent overtightening and the use of medium thread lockers where fastening locations utilize revenues and/or where no locking nuts or mechanical locking-type fasteners are used.

INSTALLATION

1. Safely raise the vehicle off of the ground.

2. Trim both the left and right wheel well air guides flush with an undertray. The trim line is shown in yellow on figure to the right.

3. Remove front bumper.

4. Trim and remove the highlighted portion of your lower splash pan. Trim line is shown in yellow below.

5. Ensure your vehicle is on an even surface. Place a Bubble Level or Angle Finder on top of your crash bar and check for levelness. If the crash bar is not level, slightly loosen the eight 16mm factory crash bar bolts (4 on each side). Tap the crash bar in the proper direction to make adjustments. Retighten the eight bolts and check the level. Repeat this process until proper levelness is achieved.

6. Locate the four pre-existing holes on the bottom side of your crash bar (two per side). Using a Drill, 21/64 Drill Bit, and some Cutting Lubricant, enlarge all four holes. Continue this process stepping up in sizes 23/64 to 3/8 to the final size of 25/64. Clean up holes with a Deburring Tool and apply some Touch-Up Paint to prevent rust.

7. Use a M6x1mm Rivet Nut Tool to install the M6X1mm Rivet Nuts from HARDWARE (A) into the holes you drilled. Put the four bolts aside for use later in Step 13.

8. Use a Ratchet and 16mm Socket to remove the two bottom outermost crash bar bolts. (one on each side circled in green)

9. Disconnect both horn electrical connectors. Use a 10mm Socket to remove horns from brackets. Use an M10 Triple Square to remove the horn bracket from the crash bar. (one on each side circled in yellow)

10. To assemble the Pedestal Feet onto your Main Pedestals, install HARDWARE (B) and tighten using a Ratchet and 10mm Socket as shown below.
    NOTE: There is 15mm of height adjustment in increments of 5mm depending on which holes you choose. We recommend starting with the second from bottom holes. If you wish to run at the highest setting, some additional trimming of your front bumper may be necessary to make room for your rear lateral support.

11. To assemble the Pedestal L Brackets onto your main pedestals, loosely install HARDWARE (C) using a 4mm Hex Wrench, Ratchet, and 10mm Socket as shown to the right.
    NOTE: You will fully tighten in step 15.

12. Loosely install your factory horns onto the Main Pedestals with HARDWARE (D) using a Ratchet and 10mm Socket.
    NOTE: Rotate your horns as shown below so that the connector faces the rear. You will fully tighten in step 13.

13. Using a Ratchet w/Extension, 10mm Socket, and Medium Threadlock, use the leftover bolts from HARDWARE (A) to loosely install your Main Pedestals into the rivet nuts on the bottom side of your crash bar. Loosely reinstall your two factory bottom outermost crash bar bolts. Use the two remaining 5/16 washers from HARDWARE (D) to loosely reinstall your two factory triple square horn bracket bolts. Reconnect your horns (rotate if necessary) and tighten the M6 Locknuts with a 10mm Wrench.
    NOTE: The AC Lines on the passenger side (U.S. Spec) may need slight massaging towards the center of the vehicle to install the Main Pedestal. BE VERY CAREFUL NOT TO KINK OR DAMAGE LINES AS THEY ARE FRAGILE AND MADE FROM ALUMINUM. Test fit before moving AC Lines. See the yellow arrows for reference.

14. Use a 4mm Hex Wrench to remove the twelve bolts and twelve washers from both the Front and Rear Lateral Supports. Set hardware aside.

15. The goal here is to “square” your bracketry. Use a 4mm Hex Wrench to install eight of the bolts from step 14 through lateral supports, into your main pedestals, and tighten. With both lateral supports installed and brackets squared, tighten all main pedestal hardware connecting to crash bar. Remove lateral supports and set aside.
    NOTE: Slight rotation of pedestals may be needed in order get all brackets in line. Lateral Supports are directional (see diagram ON NEXT PAGE to identify and understand).

16. If you purchased the optional Cooling Ducts, you will install them at this time. Use a 3mm Hex Wrench and 8mm Wrench to install your cooling ducts. Tighten hardware.

17. If you purchased the optional Center Skid Pucks, you will install them at this time. Use a 4mm Hex Wrench and Medium Threadlock to install your Center Skid Pucks. Tighten hardware.

18. Use a 4mm Hex Wrench, Medium Threadlock, and HARDWARE (E) to install your Outer and Center Air Dam L Brackets. Tighten hardware.
    NOTE: Fully tighten hardware at this time.

19. Using a 4mm Hex Wrench and Medium Threadlock, loosely reinstall both the Front and Rear Lateral Supports back onto your Splitter Blade with the twelve bolts and twelve washers that you set aside during step 14. Slide both supports towards the trailing edge (rear) of the Splitter Blade.
    NOTE: REMEMBER – LATERAL SUPPORTS ARE DIRECTIONAL Use the same approach as step 15 (pages 23-24) to ensure that the Main Pedestal mounting holes (circled in red) are on the appropriate side off the centerline of supports. Hardware should be loosely installed with just enough tension to allow for lateral supports to slide freely.

20. Starting with either side, line up the the hole of Center Air Dam L Bracket with the Air Dam as shown. Be sure to fit the teeth within the channel on Splitter Blade. Using a 2.5mm Hex Wrench and Medium Threadlock, loosely install HARDWARE (F) through Air Dam and into the Air Dam L Brackets. Repeat the process on the opposite side. See the next page for a visual reference of the Air Dam fully installed.
    NOTE: DO NOT FORCE BOLTS AT ANGLE OR IF YOU FEEL APPARENT TENSION. BOLTS ARE ALUMINUM AND CAN STRIP IF YOU USE EXCESSIVE FORCE. Take your time and start all bolts by hand working your way from center to outside. You will need to press the Air Dam into place one section at a time. Once all bolts are threaded and the Air Dam is properly seated in the channel, fully tighten starting from the center and working your way outward. Continue to page 30 to view a visual representation of the Air Dam fully installed.

21. Raise your Splitter Blade up to the vehicle lining up the eight unused holes on Lateral Supports to your Main Pedestal Feet. Using a 4mm Hex Wrench and Medium Thread Lock, loosely install HARDWARE (G) through Splitter Blade, Lateral Supports, and into your Main Pedestal Feet.
    NOTE: 1” FENDER WASHERS ARE USED FOR LARGER INSIDE POCKETS (RED) / 18MM WASHERS ARE USED FOR SMALLER OUTSIDE POCKETS (GREEN). If needed, you can partially thread one bolt on each side and let the blade rest before installing the remaining six. Continue to next page for a visual representation of this step.

22. This bracket system allows for the Splitter Blade to slide forward and backward to achieve the tightest possible fit between the Air Dam and your Front Bumper. Slide your Splitter Blade towards the rear of the vehicle closing the gap between your Air Dam and Front Bumper. Using a 4mm Hex Wrench, fully tighten all twenty fasteners circled in (RED).
    NOTE: It may be necessary to rotate the splitter blade (pivot at the center line) to line up your Air Dam evenly with the edges of your Front Bumper closest to wheels. There is enough tolerance within the slots to allow for this adjustment (see illustration notes in green).

23. Install your Wheel Well L Bracket with HARDWARE (H) using a 4mm Hex Wrench and Medium Threadlock. Fully tighten.

24. If you purchased the optional Tire Spats, you will install them at this time. Use a T-25 Torx to remove the four factory T-25 Torx fender liner screws (two on each side). Use a 4mm Hex Wrench and Medium Threadlock to loosely install HARDWARE (I) as shown. Using a T-25 Torx, loosely install the four Tire Spat T-25X19mm screws and Spacers (two on each side) as shown. Fully tighten all Tire Spat Hardware.
    NOTE: You will be applying slight pressure to bend your tire spats so that they take the shape of your wheel arch. HARDWARE (I) must be loosely installed to line up the remaining T-25X19mm Fender Liner Screws. The slots are present for height adjustability at your Main Pedestal feet.

25. If you did not purchase the optional spats, you will install the Wheel Well Supports at this time. Starting with either the left or right side, Use a T-25 Torx to remove the lower factory T-25 Torx fender liner screw (one on each side). Align the top single hole of your Wheel Well Support with the lower fender liner hole and reinstall the factory T-25 screw. Install HARDWARE (I) using a 4mm Hex Wrench and Medium Threadlock. Fully tighten all hardware.
    NOTE: The slots are present on the Wheel Well Supports for height adjustability at your Main Pedestal feet.

26. If you purchased the optional Splitter End Plates, you will install them at this time. Slide the opening of the End Plates over the recessed pockets on the bottom side of the Splitter Blade. Using a 4mm Hex Wrench and Medium Threadlock, install the M6X25mm Bolts and tighten.
    NOTE: The End Plates will lock into place when properly seated inside the pocket.

27. If you purchased the optional Rearward Tray, you will install it at this time. Use a 4mm Hex Wrench and Medium Threadlock to install the eight M6X18mm Bolts and 18mm washers (circled in green) and tighten. Use a 5mm Hex Wrench and Medium Threadlock to install the three M8X30MM Bolts and 3/4″ washers (circled in red) with appropriate spacers (check note). Fully Tighten.
    NOTE: If you are running the splitter at its highest setting, you will not use spacers. The lowest setting requires a 1/2″ spacer. Second from lowest requires a 1/2″ spacer. The third from lowest requires a 3/8″ spacer. The highest setting requires no spacer. Be sure to check the surface transition from the underside of the blade to the rearward tray for levelness. Different spacers at different heights may be needed depending on rake. Overall unit AoA (angle of attack) should be roughly 1.5deg. If your AoA reads much higher north of 2deg, we recommend adjusting your suspension to reduce forward rake or possibly shimming your rearward pedestal feet mounting points. Between the five MQB Golfs that we have tested this system on, they were all within .5deg from one another.

28. CHECK ALL HARDWARE FOR TIGHTNESS TO COMPLETE INSTALLATION.
