The Bimmerworld engine mounts are currently on backorder, doesn't say when they will have stock. Edit: called and asked, they could not give me a date, but said should be in soon...
What type of material do these mounts utilize? polyurethane?
Are AKG's polyurethane motor and tranny mounts a no go then since they're polyurethane?
motor: (#MTS368MM) "for street or performance use". Polyurethane 80A (straight bolt-through).
tranny: "Group N Transimission mounts - Polyurethane 80A" (#GNTM 3036)
Seems like the BW engine mounts, along with the RE tranny mounts are the best choice for some added rigidity, while attempting to keep NVH etc. low, and staying away from polyurethane.
This is what i'd like to get, but the damn BW's are on backorder.
What about FCAB's?
AKG #FCN4609 (polyurethane 90A) "recommended for race street or high performance use". thoughts?
What about RTAB's?
AKG #RTAB369 (polyurethane 90A with aluminum sleeves) "recommended for street or performance use". thoughts?
ps, while doing my 4.10s & subframe reinforcement install, pretty sure i'll be going with:
for subframe: AKG #SF469 (polyurethane 90A/Black)
for diff: AKG #DM463 (polyurethane 75D/Red)
