I can vouch for Nick, I have shipped to him in Belgium before. OEM Si springs if I recall correctly.I have a set of OEM Si arms. If you are in a Belgium, shipping will be killer.
From the "suspension general knowledge" topicI thought it was only the rear trailing arms on the Si that got the TypeR upgraded bushings. As long as you are willing to spend the money I am sure someone on here will have their stock Si arms collecting dust.
