2. Front Splitter Install
2.1. Velox is not responsible for damage to you or your vehicle by following this manual and/or
installing Verus Engineering products.
2.2. We begin by jacking the car up. You’ll want to choke the rear wheels and use the e-brake.
2.3. Place a jack stand on either side of the car, you can use the frame rails or the pinch welds.
2.4. With the front of the car off the ground, we’ll want to start by removing the underbody
plastic piece. This piece is quite large and has multiple plastic push rivets and a few bolts
holding it on. There will be six push pins (shown in red), and three 10mm bolts to remove
(shown in yellow).

2.5. We now install the rivet nuts into the car’s underbody. View the below photo to ensure the
correct holes are used. No holes should need to be drilled! The photo below is only the
passenger side of the car but the driver’s side is a mirror image.
2.6. To properly install the rivet nut, you’ll want to thread the rivet nut onto the tool as shown
below.

2.7. Place the rivet nut into the hole. If you’d like to use the rivet nut backing washer, you’ll
need access to the top side of the material you are riveting onto. Note, the backing washer
is not necessary but will decrease the chance that the rivet gets pulled through the bumper.
2.8. Using the 9/16” wrench and the 5mm allen wrench, hold the nut steady and tighten the
allen bolt. You’ll have some initial resistance, than the rivet nut will begin to pull tighter on
the material. Use oil on the threads to ensure they do not gall.
2.9. Alternatively you can purchase or rent a rivet nut install tool from your local hardware store
or automotive store. Shown below is another tool to use for install which is easier to use.

2.10. Below are pictures of a properly installed rivet nut. We did not use the backing washers
here though feel free to if you would like, they are supplied with each kit.
2.11. If you own a BRZ, you’ll need to remove the bumper to install the support rod kit.
Skip to step 3. If you own an FRS, you can remove the grille without a large issue and can
continue on with the steps below.
2.12. Install the two M6x1.0 x 16mm BHCS with two washers on the wheel liner plastic (left
and right side).

2.13. Install the splitter with the M6x1.0 x 30mm BHCS with large washers on each of the
rivet-nuts.
2.14. Utilize the aluminum spacer and the 30mm long BHCS on the two most rearward holes.
2.15. Finally, install the (2) radiator support bolts, with spacers and nut as shown below.

2.16. We suggest to leave all bolts loose until they are all in and then tighten from the inside
out. We also suggest you have the splitter held up by 4 or more bolts before letting the
splitter free hang.
3. Front Splitter Race Upgrade Installation
3.1. We assume you are beginning the install at step 2.10, with all the rivet nuts installed but the
splitter still off the car.
3.2. At this time we can install the splitter vanes, which add downforce over the Street Front
Splitter. Locate the (16) engraved hole centers which locates where the splitter vanes are to
be installed.

3.3. Utilizing the center punch and counter sink, increase the size of these engraved holes to
decrease the chance of the drill bit wandering while drilling. Using a drill and 1/4" drill bit,
drill the 16 holes as straight through as possible. Place the splitter on something soft to
reduce scratching the surface (I used a towel on the leading lip and then propped it up on the
wood as shown below).
3.4. Find the bags with the M6x1.0 x 35mm long FHCS and the M6 Nyloc Flanged Nuts. Use a
4mm Allen wrench and a 10mm socket on a ratchet to tighten these vanes to the *bottom* of
the splitter. There is no need to over tighten these as the nylon in the nuts will lock the bolts
in place.

3.5. Place the splitter somewhere safe now that the vanes have been bolted on. Next up is to
remove the plastic tray between the front bumper and the radiator support. This will allow
you to reach your hands up to tighten the nuts and bolts for the crash beam supports. Remove
the plastic push pins with a screwdriver (located in purple/blue). Also remove the (3) 10mm
bolts with a ratchet and socket (located in red).
3.6. We have to remove the bumper for this part of the install if you own a BRZ. If you own an
FR-S, the bumper can remain on and the grill removed and you can skip to step 3.11.
3.7. To remove the front bumper, remove the strip of 10mm bolts and plastic push pins across the
top of the front bumper under the hood.

3.8. Then on each side of the car in the wheel wells, remove 4 plastic screw pins. Three are
located down low (see below photo), the last one is up by the turn signal on the inside of the
fender. Ignore that the splitter is installed in this photo, it was taken after the installation.
3.9. The turn signal has to be removed to expose the final plastic push pin and then the front
bumper will come off. There is a metal tab that needs to be push towards the *front* of the
car. The arrow in the picture shows this well. I used a flat head screwdriver to push this
forward and then gently pried the signal away from the car.

3.10. The final push pin is circled here! Remove this and gently pry around the front bumper
to remove it completely.
3.11. Up next is drilling the front crash beam. You will notice that there are raised portions of
the crash beam and then portions with spot welds on it. You will want to drill the raised
portions as drilling through a spot weld can get bad quickly. The splitter supports were
designed around an 18.50” spread, which leaves *6 raised* sections between the brackets.
Center punch the next 4 raised portions, using the brackets to ensure that you can bolt them
on the crash beam in the location necessary for a proper install with the grill.

3.12. It is recommended to use a starter drill bit next (top left of picture) as these can greatly
help cutting through sheet metal and ensuring that the drill is going through the material
straight.
3.13. Using the 1/4" drill bit, drill through both parts of the sheet metal. Vacuum out all of the
metal shavings you can. It is recommended to spray the holes with spray paint (at the very
least) and underbody rust resistant if you have some. This ensures that the crash beam will
not rust for years to come.

3.14. Ensure that the brackets will fit and that they can slide together till there is a 10mmgap
between the two mounting holes for the splitter tie rods. Do this by using the (8) M6 x 1.0 x
16mm long BHCS, (8) M6 x 18mm, and the (8) M6 x 1.0 flanged nuts. You do not need to
tighten these down, just enough to know if the brackets will work once the bumper is put back
on. Once you ensure the holes were drilled properly, remove the brackets and reinstall the
bumper in reverse order
3.15. Once the bumper is back on, start by installing the crash beam mounts first. Like before,
use the M6 x 1.0 x 16mm bolts, a washer on the bolt side and the nut on the back side of the
crash beam. It will likely be necessary to move the horn; this can easily be done by loosening
the 10mm bolt. Do *not* fully tighten the brackets to the support yet. Once all 4 of these
brackets are loosely installed, install one side of the splitter rod on each side. Tighten this to
ensure the brackets can fully clamp the rod end. Once this is done, find the final position (left
or right) you want the splitter rod to rest and tighten the crash beam mounts fully. Below is
both a BRZ and an FRS install (note BRZ install has our old, obsolete rod end design).

3.16. Using the 4mm allen wrench and the 10mm wrench, tighten the rod end into the clevis,
a washer is used between the bolt and the clevis. Use the 25mm long bolt and the M6
flanged nut on the other side.
3.17. With the splitter fully installed, we can make the holes for the clevis to bolt to.

3.18. Place the lower aluminum plate underneath the splitter, roughly centered, and mark the
center of the two slots as shown below.
3.19. Center punch this mark then drill straight through this mark with a 1/4" drill bit. This is
how we will mount the bottom of the support rod to the splitter.
3.20. Using the 25mm long M6 BHCS and the large fender washer from the bottom side, bolt
through the support bracket, splitter, and capture the clevis to the top side of the splitter.
3.21. Ensure that the splitter is near horizontal by using a level. The front of the splitter’s
level is now controlled by the support rod system. Lengthen it to lower the front of the
splitter, shorten it to raise the front of the splitter. The splitter rod is both left hand and
right hand thread, keep this in mind.

3.22. At this point, everything should be installed on the car and can be fully tightened.
Ensure all bolts and nuts are tightened on the underside of the splitter and the support rods
are fully tightened as well.
3.23. On the support rods themselves, hold the support rod steady and then tighten the nut
on each end to keep the support rod from turning.
3.24. We have now concluded the install of both systems, admire your hard work! The
splitter can see over 200 lbs of downforce at this point. It is not wise to stand on the
splitter, it can handle this load but the aluminum bracket beneath can bend and lead to
distortion. Air pressure is even and two foot points are not.
