This is the kit. Comes with the locking nuts to lock in the height:
You will have to trim the length of the longer eyebolt in the kit for the rear set. I just measure the original rubber rods and shorten mine by 10mm (overall length, not just the longer eyebolt) on all 4 corners. If you want it to sit higher shorten them some more by screwing them in. Make sure you give yourself enough space inside the standoff when you trim the longer eyebolt. Once you have them on and oriented so there is no torsion on the rubber inserts, lock it in with the locknuts. Be careful not to break the sensor arm when you remove the original rubber rods.
