First and foremost, let me tell you what I was working with:
Completely stock 2012 WRB WRX Limited
As the title of the thread states, I just installed a Kartboy short throw shifter and front/rear bushings this weekend. The install went fine - everything seemed to fit well. I noticed right away the difference the short throw makes with every gear change. I especially like the stiffness it it has with both front and rear bushings installed versus the factory setup.
Herein lies the problem. When I'm in any given gear past 3k RPMs and let off the gas to decelerate, I hear what can be described as a grinding-like noise coming from underneath the car. The noise is most noticeable in 1st, 2nd, and 3rd gears. It only occurs while letting off of the gas. I have the day off Wednesday, so I'm going to put it up on ramps again and check it out.
But at the moment, I'm somewhat concerned as I don't want to destroy my baby. So I would greatly appreciate any help or advice anyone has to offer.
Thanks in advance!
