Parts List: Steering & Suspension Refresh, Updates and Upgrades

Post by TimU »

Living in Australia has many benefits. Availability of E24 parts with fast shipping is not one.

In my quest to "do it once", I've tried to compile a list of all the parts I needed for a Front & Rear Suspension and Steering refresh/upgrade.

I have no idea when some of this stuff was last replaced by the PO, so I opted to replace all wearable items such as bushings, bearings and ball joints, as well as all bolts, washers and nuts unless otherwise noted.
Overkill? Probably :-k
But given our long shipping times, I'd rather over-order and have spares, than be off the road for weeks while waiting on 1 friggen bolt.

Car: 1986 BMW 635CSi (E24)
Australian Delivered, RHD

Upgrades planned during my refresh. (Part numbers below) Green is an upgrade.
Orange is optional/alternate.
Part quantities are TOTAL needed to complete both Left & Right sides for that job.

Yep, honestly that was my main motivation for posting.
Previous posts rarely included part numbers, and if they did, the part numbers were spread throughout various comments or threads for single components.

I wanted to share a one stop shop for parts that also included some of the common upgrades gleaned from the depths of expert brains and comments before me.
