Good choice for the WRX VBB
Got this kit for my manual transmission '24 WRX and ended up using less than 4 bottles to drain and fill front and rear. Great stuff! I'd recommend getting a hand pump from an auto parts store or Amazon in case you overfill through the transmission dipstick hole and need to pump some out. Just make sure the pump tube is nice and tight so it doesn't fall off into your transmission case.
