Again....I have forgotten a lot. LOL.

Just picked up a set of Eibach Pro springs. Thinking I might use new iso's instead of the 10k iso's coming with coils. Maybe

Poly aftermarket or Rubber OEM? Why?

Also anyone know the part number for the shorter sway bar end links from Energy Suspension? I use to know it but not anymore. I think it may be 9.8117 or something like that?

I picked up a set of poly isos so I had a set on hand when I did the springs on my Mach 1 but I just reused the stock rubber ones. They were in good shape yet and the poly is supposed to add a little height to your drop. The isolators are only for noise. It's hard to find a rubber set anymore cheap so you'll probably have to go poly if yours are shot.

I have a good set of front iso here with thr coils.

I remember the last three I dropped I left the iso out and wrapped the coils with electrical tape to help reduce noise. Lol.

May stick with my stock rubber iso. As I definitely don't want to reduce the coil drop.

This is my first set of eibach I will be installing. The last three were FMS or LMM coils.

I have poly in the rear because mine fell apart. No complaints. Don't think it changed the height much if at all.

I've considered taking them out to get a little more drop though
