Hey Fly, I can help you out with the spring install. I'll show you a trick I learned from DPS Tuning.
Works flawlessly, safe, and done in only 30 seconds. Without using a wall-mount spring compressor. Props go to Bryan at DPS Tuning!
WeatherWarrior, there is a DIY shop out in Glen Burnie as well. I just learned about it from a couple WRX guys I met at Annapolis Subaru. However, when I showed them this shop, they may start going down there since the shop is a lot bigger and cleaner, plus the staff at the Glen Burnie one is apparently equivalent to going to SE DC and asking a chop shop to fix your muffler.
I don't know of the address for the one in Glen Burnie, but from what I heard about it, STAY AWAY!
Also, I forgot to add what day people would be interested in meeting up and doing a caravan trip down there. I am going to stop by there soon (this weekend was a wash) and see if they can let us do a meet there and possibly apply for a group discount.
