Tip for those who have yet to install their coilovers:
Follow what MPP posted earlier in this thread (quoted above). I exchanged emails with Jesse and he confirmed that we should only be using the parts shown, arranged in this sequence (from top to bottom):
I purchased my kit in mid-2019, but the kit has evolved since then. The tender springs, rubber isolators (OEM, as well as any provided in the box), and the thin plastic and metal rings are no longer used. If your kit contains these items, disregard them. If your kit has the tender springs, reach out to MPP so they can ship you the composite spacer to use instead.
- OEM shock hat
- composite spacer
- main spring
- perch adapter
- perch
It seems like there will be more NVH without any type of isolator between the OEM top hat and the composite spacer not just with MPP coilovers but any coilovers per several accounts on this forum from regularly contributing members.
I'm a bit surprised to hear that is the recommendation per MPP.
