Drift Talk: Usukani YD-2 upgrades part 1
We were lucky enough to pick up a team sponsorship from Usukani last month and the first of our parts arrived recently and I will admit to being a little selfish with our first order as it mainly consisted of YD parts. After getting back from my honeymoon I set about stripping the YD ready for some Usukani upgrades.
So let me run you through what I have changed and give you the Yokomuki opinion on each of the upgrades.
YD-2 steering rack
The aluminium steering rack from Usukani is a huge step up from my standard plastic rack, very easy to assemble. It’s worth noting you will need to dissemble you existing rack first as some of the parts will need to be reused that came with the original kit.
I made massive changes to my YD all at once so most of my first run was trying to dial in the chassis but you could feel the difference the new rack made, all the slop in the steering was taken away and the steering input felt much more direct.
Carbon Chassis and top decks
Another big change for the YD was the addition of the carbon chassis, the Usukani carbon feels very good quality and is perfectly machined I was very impressed with the finish. One thing I was worried about when I upgraded to the carbon deck was losing the chassis flex the plastic chassis offers but Usukani has this covered with the choice of two top decks.
High traction which creates a little more flex and the low traction option which stiffens the whole chassis up. I have had short runs with both options fitted. One thing I have found using the low traction option is it allows my suspension to have more impact on the handling as the chassis flex is taken out of the equation. In low traction mode all the weight shift in the chassis flows through the suspension and the YD felt more agile as a result (Worth pointing out I am no setup guru and this is how it felt for me)
If you are currently running the entry level YD I would recommend giving the Usukani carbon conversion a whirl.
The new YD-2 adjustable rear lower arms
I believe I have the first set of these in the UK, they are visually stunning and look like they belong on the Bat mobile. They offer toe adjustment direct from the rear arm in the same way the original Usukani adjustable rear arms did, big bonus with the YD arms is they are the exact same length as the standard rear arms so you want need a new set of drive shafts.
Unlike the other Usukani arms there is no hub integrated in to these you do however get two different ways of mounting the shock to the lower arm at the moment I have only used them with the shock mounted directly to the arm itself, provided in the packaging are the parts to attach the shock to the standard hub (I will try this next time and report back)
Toe adjustment again is very simple but due to limited running time I have yet to fully experiment with these arms so I will have some more in depth info very soon. I would recommend picking up some spacers though as there is a little play compared to the standard arms Usukani have you covered here as they have just released a range of black spacers.
All the above upgrades are fantastic and are definitely a step up from standard although I would recommend changing one thing at a time so your chassis doesn’t completely change its behaviour but after some help from Dan at NRD my YD was going round beautifully a big step up in terms of handling from where it was. We will be taking a look at the new version 2 mag mounts and the D4 carbon conversion soon.
As always you can get all your Usukani upgrades in the UK from Asbo-RC, if you are not in the UK contact Usukani to find your local stockist.
