The Build – Part 8
This part will complete the front suspension build. Tamiya has included 3 sets of springs to help you tune your F104X1 to different track conditions. You can also adjust ride height but putting the shims above or below the steering upright.
Build Notes:
After building the front end, it is suggested that you apply a thick-ish oil to the front suspension to help smooth it out. I use 3000wt Team Associated Gear Diff Lube. That seems to work really well and it’s thick enough to stay in place.
Insert the aluminum balls into the upper suspension arms. Do this for both sides. They are non-directional so that doesn’t matter.
Insert the 3x35mm screws through the chassis and into the ball connector nut. If you are using the optional electronics mount system, you don’t need the front upper deck. If you do remove that, it’s optional to place spacers in it’s place. Pop the upper suspension arms onto the ball connector nut.
Snap an e-clip onto the kingpin and install a front spring. The F104X1 comes with 3 different sets of front springs. I use the stiffest, the golds, simply because we are using a super soft front tire and the gold spring helps control front dive. Build 2 of these.
The steering upright comes pre-assembled with the F104X1. You will need to install the ballend, though. Use the stock location. Do this for both sides.
Slide the kingpin up through the lower suspension arm, through the spacers and the steering upright. Spacers can be loaded per the manual; thick below the steering upright and the two thing above it. Do this for both sides.
Capture the assembly with an e-clip on top. Install the setscrew into the back of the axle. A dab of blue loctite will help keep it in place. Do this for both sides.
Pop the steering ballcup into place. Do this for both sides.
