KYB makes a passive rear stock strut. It will fit. You can get them anywhere you want. You can also call your dealer to ask them for the stock rear passive struts. Oh they are struts not shocks, just incase anyone at a tire store asks. To confirm my info you should call your dealer or KYB. I think Blisten makes one too. On the net I have found them for $43.00 each.
I had to use the sse option but both sse and ssei have the same rear system. You will need to disconnect your adjustable rear suspension but the dealer can tell you how to do it properly even if it doesn’t work.. Its easy as pulling a plug.
I have performance adjustable coilover kits that can use Koni or other inserts and they are built to race specs. My product comes with a warrantee and are professionally built by an engineer. I can have them set up so you are riding in luxury or set up so you are slammed and you can feel every grain of sand.
