BuddyClub N+ Coilover Install Guide for Honda CR-Z
Front: Disassembly -
1. Remove the wheels
2. Remove the top nut holding the shock by removing the rubber cap and holding the threaded center with an allen key and turning the nut with an open wrench.
3. Unbolt the swaybar end link by also holding the thread with an allen key while turning the nut with an open wrench.
4. Remove from the bracket and unclip the abs sensor line.
5. Bungee or strap the hub so that it doesn't swing out too far so it doesn't pull the half-shaft out of the cv joint when removing the shock. Also a good idea to put a jack or something under the lower arm so it doesn't hang too low which can also let the half-shaft fall out.
6. After securing the hub or having someone hold it, remove the 2 bolts holding the shock to the knuckle and pull out the whole assembly.
7. For the Buddy Club N+ suspension, remove the collar from the top of the stock shock and re-use it on the Buddy Club Coilovers
