    Armrest Extension

    Posted by Andrew Hafner on May 13th 2021

    This thing should be original equipment - with the normal armrest lid it's the perfect height and doesn't interfere with shifting. Auto-X approved! Perfect for spare masks, among other things. If you get the extending arm rest lid and combine it with this, it may be too high for most, even when it's down, and interfere with shifting.

    Great Addition / Better than USDM Option

    Posted by Ben on May 5th 2021

    Overall, this is a great option to the USDM extension as it 1) doesn't impede on the cupholder area and 2) you can re-use your original matching console lid. Only downsides are that the texture of this piece doesn't match the existing plastic part texture and that it does slightly impede shifting; my elbow hits it. But overall, I'm happy with it--great addition, great quality and superfast shipping from SB.com.

    OEM Quality

    Posted by Andrew Hafner on Apr 13th 2021

    Overall I like this item. OEM quality and fit so you know it works. Great positioning especially for long trips. However, with the extending armrest on top of it, my elbow tends to hit the latch and then it's in the way. I'm 6' so just a heads up. I would stick with non-raising armrest if you get this item.

    Must have mod

    Posted by Walter on Mar 31st 2021

    This is a must-have for your car. I had the USDM armrest extension in my 2014 WRX and it did the job but didn’t have any extra storage space and it had a rattle. This matches perfectly and maintains the nice fabric armrest cover that comes with the STi.

    Great Product

    Very useful. Should've come installed from the factory but definitely worth purchasing if you enjoy using your armrest as an armrest.

    JDM dual armrest extension

    Posted by Tommy Tran on Dec 30th 2020

    It’s a perfect fit. Installed in my 2020 STI Limited, the dual armrest installed in with no problem. Subaru should have installed this from factory. Perfect height and add on.

    Much needed armrest booster. This should be standard from the factory

    Posted by Edric on Oct 7th 2020

    What a great mod! The factory placement of the armrest is a joke! Even the factory arm rest extension accessory isn't adequate. What is needed is the proper height and for me, this JDM upgrade is well worth it. Just note that with this mode, the raised height may cause the arm rest to be very slightly wobbly so make sure not to place too much uneven weight on this.

    Im 6'4 with the seat all the way back and it is the perfect height to rest your arm. Doesnt get in the way of reaching the shifter. Easy to install
