Introduction
The DDU Mount comes pre-assembled to some extent. All extension arms and the
end pieces are assembled as one piece ready to mount.
Regarding the needs for your specific setup, we tried to supply enough parts for you
to be able to adjust the position of your DDU perfectly.
Depending on your needs, not all parts are required but we chose to include them to
be as complete as we can.
First, here is a schematic of all parts mentioned throughout this manual.
A: Mounting piece
B: Extension 75mm
C: Finger nut
D: Extension 50mm
E: End piece DDU side
F: Vertical bar
G: Horizontal bar
H: End piece (open ended)

Mounting
OSW/SC/VRS
We find it is easiest to mount the DDU mount when it has been completely
assembled. Lay out all the parts needed, checking before to know which extension
to choose, or maybe combine them to reach the desired length.
Lay all parts flat and assemble like the following. Don’t tighten everything fully, but
just enough so you can transfer the entire assembly to your intended platform.
Replace the existing bolts with the countersunk bolts (A6) we supply. Depending on
what motor/wheelbase you are using, you might need to angle the mounting pieces
(A) differently. For OSW/VRS users, we supply a fresh pair of M8 lock nuts (A9).

Attach the DDU by using 2 or 4 M5 countersunk bolts (A8) included. Using only
2 bolts is enough, while allowing for more flexibility in positioning the verical bars (F).
Now all parts are in place, you can start by tightening finger nuts in pairs as you
‘pose’ the DDU mount to your preference.
To really lock down the position,
use an Allan key to tighten the
bolts paired with the finger nuts.

Fanatec
When mounting the DDU mount to a Fanatec wheelbase, we assume you are using
a third party wheel and need the extra adjustments our normal mounting plates
can’t achieve.
For certain dashes, like below, space beween the arms can get limited. We included
a ‘stubby’ Allan key (A10) so you can tighten all bolts properly.

combined. Here are examples of all combinations you will be able to try.
