Before performing this upgrade take your whip out and get reacquainted with its idiosyncrasies. Drive it in different conditions and feel that rear differential moving around back there; making all kinds of weird thumps, thuds, clunks, and jolts.
Perform the upgrade and then notice what’s up:
Normal slow to low throttle input conditions will not reveal the hidden potential of the ARDU. In fact unless you push on the car a little bit or had a really worn stock bushing to start with you will feel nothing but a well-mannered ride. However push, on the throttle a little bit deeper and faster or shift gears with more urgency – and the benefits become obvious:
The rear end of the car finally feels connected to the rest of the car. Dare I say “more lively”. Acceleration is more composed when coming off the throttle to shift – no more squirm to the rear and it allows you to come off the throttle without need to modulate your actions to prevent the bushing from collapsing and causing the movement and associated noises from the rear diff.
Deceleration is also more composed when downshifting the change in torque is not wound up and released with unsolicited diff movement to disconcert you with a jerk forward and backward. All there is to feel is “one piece of car with one mission”. No longer does it feel like different ends of the car are doing different things.
The easiest way to sum things up is - the change in the behavior of the rear end of the car with the addition of the ARDU is the equivalent of adding the snub bushing to the motor up front. I’ve known I needed this for a long time – ever since I first drove my whip with upgraded engine/tranny mounts. I was surprised no one spoke of it – well I guess SOMEONE did and Apikol listened.
Next: Stay tuned for DIY instructions.
