This is a great upgrade for the drifters right here.
If you've installed this diff, you see that drifting could be verry easy.
If you brake on your transmitter the car only brakes with the rearwheels, so you have a handbrake effect.
If you pull the brake and steer into the corner the car gets sideways much sooner and much easier than it goes with a standard diff.
And you can make faster transfers (if you drift to the left you can 'transfer' faster to the right) than a normal diff.
You can make tighter turns with this diff.
The car will be more stable as well.
Becouse the diff is locked if you put on the gas.
This diff is verry durable, it has steel diffcups and the diff itselfs is from alloy.
You get a spare gear with the kit as well
It really looks awesome, with the alloy.
The discription is verry clear to, so you can build it easily.
It's a great upgrade for racers and grippers too.
You have less friction, so you can drive longer on your battery.
