Folks, here is my attempt to run 5th gen's LGT Swift springs on my 2013 2.5i 6MT. No one really know how it will fit because Subaru made some improvements to the suspension of the 2013s. It was a gamble for me, but I think things worked out pretty well. Here are some pictures:
I took some measurements from the ground to the top middle of the wheel arches:
Left Front: 26 3/4"
Right Front: 26 11/16"
Left Rear: 26 7/8"
Right Rear: 27 11/16"
I say the overall car sit very even with the exception of the right rear, where it sits almost an inch taller than the other three. I believe there is something I can do to correct this, but I am too lazy to go back under the car. The stock can be fitted 0 deg and 180 deg. I believe rotating it 180 deg may help it to sit level with the others. Has anyone corner balance a 5th gen? Is the right rear the lightness?
So far I have driven on the new setup for about 40 miles, and I live in close proximity to some very rough roads. To my surprise, the car felt almost if not exactly the same as the stock 2013 springs. This is a good thing! The car is about 1.25-1.5 inches lower, so obviously the difference is that I hit the bump travel is shorter than stock. I did a few quick high speed turns, I did not feel much improvements over the stock 2013 springs from the seat of my pants. This makes me wonder how do the spring rates of the stock 2013 springs compare. If you have a 2013 2.5i, I would get these for aesthetic purpose only.
While I had the car apart, I took the liberty to write down the part numbers there were stamped on the struts/shocks.
Front: 20310AJ07A, 20310AJ06A
Rear: 20365AJ04 (note: there is no A behind the 4)
I am not sure how these would compare to the pre-2013 LGT, or non-GT models. Maybe a good option if your stock setup are blown, and time for some replacement.
I will have to find the motivation to get back under to car to fix the right rear. Hopefully I can get it within half an inch to the other three. <Update> The right rear was slightly corrected, more details in Post #19.
