Whiteline positive kit feel?
 

Just installed whiteline positive kit bushing, read through everything and understand the use of it.

Overall, it does provide very "positive" input.

But I have also notice when I am accelerating, I can hear the gear spinning, almost as if my car is an RC car. Is this normal?

Yes. This kit fills in the gap between your subframe and the body of the car. Any noise the diff makes has been amplified and transferred through the body.

I'm assuming you mean the Whiteline Positive Traction kit, right?

So you are saying the car's sound now goes with the little RC antenna on the roof?
