Once again Yeah Racing is killing it with an entire set of Hop-ups for the YD-2.
And as usual, I had to restart from scratch by putting my chassis back to stock to really appreciate the upgrades. Let’s take a look at all the goodness.
Carbon Lower and Upper Decks:
Well, almost stock since I kept my weight shift kit 😛
I really like the look of the carbon plate in their conversion, but the most amazing thing about this kit is the price! $50 for the lower deck, and $15 for the upper! That’s a $65 carbon conversion set! WTF. The fit is on point and the cut is actually quite good. Obviously you won’t get some super smooth edges like a high end deck, but you’re not getting some cheap knock off quality either. It’s just right and will do the job fine.
Now let’s look at the alloy!
The kit brings you the following: a motor mount, front shock tower, front lower arms, front upper arms, rear shock tower, rear lower arms, adjustable length CVDs, a new steering bridge, and cool looking bumper plate. And once again, the price is ridiculous! this entire pack is under $120 and provides you all the adjustability needed and some! The whole thing include clear instructions for installation and adjustability.
The motor mount allows you to setup your motor in 3 positions: stock – high upfront – high back.
Since I’m using my weight shift kit I opted for the high back position and it worked wonders. I really fell in love with this piece because of it’s super sharp design and graphics. It felt very reminiscing of a Gundam look.
Lower Control Arms:
The lower control arms are also pretty impressive. The construction is super lean and almost too thin at first sight, but after assembling them and giving them a few tugs, I realized they were actually quite strong and will do just fine on the track. Now with that said, I would be careful if you go to tracks with sharp wall ends where wheels could get caught. At high speed, I’m sure these puppies won’t like a hard impact.
They have adjustable track with a single screw which make for quick adjustments and offer a lot of mounting positions for your shocks. One feature I liked a lot was that the droop screw hole has an O-ring in it which prevents your setting from changing due to shock or vibration. That’s a neat feature I had not seen used on these grub screws before, but make a lot of sense.
Shock Towers & Front Upper Arms:
The front tower is a big improvement over the stock plastic one. You basically get about 4 times more mounting position for your shocks. The fit is also perfect and lines up with rear bridge perfectly. I would not have expected less from Yeah Racing. As for the upper arms, they are quite standard for today’s trends. A lean and clean piece of aluminum with a tightening screw for the turbuckle. You re-use your factory hardware and done.
The rear tower had me scratching my head for a second when I first looked at it through the bag. I thought something was missing until I opened it and realized the turnbuckle mount was under the tower! What a slick trick it is. This is a great way to shave some weight and still keep the adjustability needed to perform. I most likely will have to mess around with the proper spacers combination to get the right roll.
One thing I thought was weird was the clearance for the damper mounting screw. For some reason, when using the inner most position, I did not remember having binding issues with my spur on the stock towers. I have not had a chance to verify why I was getting this difference but it can be easily fixed by spacing the shock tower back a few millimeters to slide a nylon lock nut in there. (sorry for the dark pic)
The Steering Bridge:
the steering bridge replacement is pretty sweet. It seems to be really close to the Carb-D system, but the bridge positions sits a lot further within the bulkhead than the last one. This should result is wider range of motion and a slightly increased angle ability. If bought by itself, this part is $17 only which is a must have on this car. Buying this by itself would already be a great hop-up for your car.
Just like the big names out there, these adjustable CVDs are a must have to pair with the adjustable arms. The construction is solid and they come with a double set screw engagement so they shouldn’t come lose anytime soon. Everything was a direct fit in the orginal rear uprights and no shimming was required.
These upgrades were not YD-2 specific but I felt like they were worth showcasing.
Since I’m building this chassis for my significant other, I ended up using some Sanwa electronic instead of Acuvance. But the Sanwa cooling is just meh… so once again Yeah Racing came to the rescue!
I ended up using the 25mm to 30mm fan adapter, the gnarly aluminum tornado fan, and fan shroud. This came out super clean and almost look like a factory setup. These fans can be hardwired to the ESC + & – battery connection to run at their full potential. If used plugged in your receiver, they will most likely get 6V like most system, but there can actually run on a fully charged lipo at 8.4V! The one thing to be careful when doing that is to not leave your battery plugged otherwise you can discharge a lipo below its safe voltage. On the other hand, I think it’s great to do it that way because it’s a good reminder to unplug your lipo once you’re done with your run. We all heard freak stories of car bursting into flames for no reasons whatsoever.
After all these upgrades you’ll be about $180 deep with alloy and carbon parts, but considering you can get yourself a YD-2 for about $170, then get decked out for such a low cost, it’s a very attractive setup. The YD-2 Plus retails around $350 and doesn’t even bring this level of adjustability so it clearly is a no brainer. As for the quality of the kit, everything met or exceeded my expectations. It’s clever, it looks sharp, and it’s affordable.
And every upgrade has it’s own set of instructions as well so it’s very easy to install.
I also added some WUN VX knuckles to replace the factory ones and the whole result came out really good. Low bump steer and plenty of turning angle.
The final result is a great chassis for about $350 (Yeah Racing products only), which will provide a considerable amount of adaptability and fun for any experience level. I also believe this chassis can easily dominate competitions if tuned right.
I did forget to showcase the bumper plate, but you can catch it on the Oversliders Instagram and as you’ll see it is just like the rest of the kit, super clean and sharp.
Overall this kit gets an A in my book and is totally worth every penny.
All these cool parts can be purchased through RCMart or your local Yeah Racing distributor.
