Perfect Dark

Hey folks, couldn't find what I was looking for so I figured I would ask. I'm planning on buying a set of the H-Techs and running them with the stock struts for now. My question is do I need the saggy butt spacers? If I do will a 3/8" set do the trick? This is for an 05 wagon. Thanks!

Not sure what exactly is going on but hopefully you folks will have some input. I was driving home one day in stop and go traffic and noticed the car sounded alot louder than normal. I got home and realized that the fans were running full out, and remembering this thread figured that it was time to get the recall done (I tried before a couple of times and the dealership kept putting it off) The next morning I started the car and lo and behold the fans weren't running. Thinking that it was just the relay I carried on my way to work. When I got to where I was going I got out only to hear the fans running full speed again. So basically if I start the car cold the fans are good but when it warms up they start going full speed and don't stop. I had the relay swapped and it didn't work, but from what I am reading the ECU should be okay as long as the fans aren't always on. Thoughts?
