Perrin shift stop with factory short shifter

Jb_utah said:

I ordered a 2018 WRX Limited 8 weeks ago and I'll thankfully be taking delivery one week from today. I have been reading all kinds of recommendations for mods, etc. One that has bubbled to the top multiple times is installing the Perrin shift stop. I have ordered and received the piece. I have watched the youtube vids on how to install, etc.

My question is this. I ordered my car with the factory installed short shifter... has anyone here installed the Perrin shift stop with the factory installed short throw shifter? If so anything different with the install?

Thanks in advance for all your help

Wondering this myself. Have the same car due to arrive in a week and wondering if it's necessary..? Have read from some that it is still worth it and others say you don't even need it. I have drove an 18 with the STS and thought it felt solid. Might just drive the car for a while and see for myself before modifying. I do intend on doing a brass shifter bushing and boomba short shift adapter plate to shorten the throw even further. Thoughts on this welcome as well

I have a 2017 WRX Base, but it came with the STI short throw shifter. Install didn't seem to be any different, very simple and easy.

FWIW, the STI STS only reduces it by about 10% apparently, if you really want a shorter throw you'll need to buy aftermarket. however I've never felt a need for it.

I'll probably go with the brass bushing and boobma shift adaptor on top of the stock STI STS plus a weighted shift knob and that will probably be super smooth and crisp

2017 wrx premium with sti short shift here. Installed Perrin shift stop last Friday and it's been awesome.

As above post, I too have the factory short shifter and installed Perrin short shift stop. Installed easily. Works well. And my shifts are delightfully short.

I would like to see the source of the above post that the optional OEM short shifter only reduces throws by 10%, for I have repeatedly heard numbers in the 20-30% range (though I do not have a factual source for that, just repeated, forum, "urban legend").

Subaru states that their short shifter "Significantly reduces shift throw lengths for crisper shifts and sportier driving feel," but again, not yet found a precise/mathematical amount of how much shorter Subaru's is.

Anyone?

My car is due to be delivered next week so when I go to the dealer I will take measurements of a stock 6-speed throw end of my car which has the STI STS. Then I will take them again after the boomba short shift adaptor install and will be able to calculate the exact percentage reduced from bone stock to short throw to short throw with short shift adaptor.

Thanks to all who replied to this thread. My car arrived almost a week early. I took delivery on Wednesday night and I'm thrilled. My question for this thread was regarding installing a Perrin shift stop with the SIT short throw shifter. I installed it last night after watching probably a dozen different you tube vids on how to do it. Some in the videos said they got little results.

I'm here to say that its a fantastic and inexpensive mod. I think it made quite a bit of difference. My guess is that those who found little benefit installed it with to much play (which is easily adjusted).

I'm currently deciding on which weighted shift knob to get and I have ordered mud flaps... and have already installed all blacked out badging.

Thanks for your help and recommendations.

Congratulations Jb_utah! I have the identical shifting combination as you, and really like it too.

Very glad your car arrived early and that you are already modding away. Happy times!!! [Both modding and driving.]

Very interesting... I'm picking up my car on Wednesday so I'll see how she feels and decide if I think I need one or not. Thanks for the input man!

I have it on my 2017 wrx and install was simple. Love it !

I have it on my 2019 wrx and really makes a good difference if put on properly. Nice clean shifts
