After reading a few posts about short throw shifters and how to go about it...
I decided again to let my local tuning shop tackle this for me too. I am pretty stupid with tools and while I watched plenty of DIY videos on youtube, my local garage was able to swap out my shifter for me in less than an hour. Sure..It costs me an extra $80..but they do a fine job and my car always comes back to me as if it were untouched.
Anyways...for those who care to know about my experience...I went with the Kartboy Short-Throw shift with the bushings kit.
When my all the panels were removed...it was discovered that an AVO adjustable shift kit was already installed. LOL!!! I did buy the car used about 4 months ago. So...to anyone even considering an AVO shifter for an 09 WRX...DO NOT BUY! It is crap. I guess stock must be just even more trashy given the AVO shifter felt like long throws through mud. My gear shifts were never precise...always a mushy feeling and well...even downshifting caused me to miss gears entirely.
I am pleased to report the Kartboy shifter with bushings has made an immense difference. Sure...it doesn't add power or performance...but it makes the drive much better. Gear shifts...up or down...under power...or not...are precise...have a solid feel and way shorter throw. I am in love with it. I know there are other makes out there...COBB...TWM...etc...but Kartboy is pretty dam good. I already had the MOMO Subaru shift knob...so kept that on.
Anyone with an 09 WRX manual considering Kartboy product...rest assured...you will be happy. STAY AWAY from AVO.
