Alright guys, pretty new to the forum and this seemes like the best one for my question. I've finally made it through all the posts and have an idea of what I'm looking for. I just need some reinforcement and/or guidance. I own a 2008 Legacy 2.5i 5MT sedan. Around 95,000 miles. DD but also like to rip twisties and do more spirited driving at times. Will be driving in MN and SD year round. She needs new struts so I wanted to upgrade struts and springs all at once. Looking at Bilstein HDs but am trying to figure out which springs to get. I wouldn't mind being lower than stock but also want some upgraded performance. Fixing butt sag isn't a priority but I wouldn't mind evening it out. From what I've gathered for springs I should be looking at pinks or swifts to match the Bilstein HDs. My only questions are these: 1) does anyone have a 2.5i with one of these set ups and if so tell me about your experience. how do you like it? How's the ride quality. Did you have issues with sag? Etc. 2) which of these options seem like the better choice for replacing struts and springs? Any help is appreciated. Will be needing to do the replacement within the next month or so. Thanks!
