Same question here as Gilad - I have a friend that's willing to sell me his STI struts (front and rear). Maybe my thread searching skills aren't the best, but I couldn't find anyone that has done this swap - and if I should expect any drop on the stock STI springs.
As for the install itself - will I need any other components or just the struts?
I have a 2016 WRX with the Sport package (Canadian car) which comes with the non-inverted fronts. Should be equivalent to a base 2016 in the states.
