Quick question ... I have some Epic springs coming in this week for my 2011 WRX and was going through the service manual regarding removing and re-installing the shocks. The manual says that when re-installing the suspension to use NEW self locking nuts (for both the front and rear shocks). I've replaced/ungraded the suspension on 3 of my previous cars (none subaru) and always just re-used the existing bolts/nuts. Is this something special with Subaru? Should I order all new nuts when I re-install the shocks? Just wondering what people's personal experiences have been with this.
