Bilstein B3 38-129230 - Replacement Rear Coil Spring for BMW E36 — Overview
The Bilstein B3 38-129230 is a direct OE-replacement rear coil spring for the E36 3 Series. It restores factory ride height and spring rate when your originals have sagged or cracked - which is common on any E36 pushing 150k miles or more. This is not a lowering spring and not a performance upgrade, just a properly specced replacement that gets rear geometry back where BMW intended it to be.
If you are building a stance setup or want a drop, look elsewhere - these are the right call when you need a like-for-like fix before an alignment or when the rear is sitting noticeably low on one side. Worth inspecting the spring perch isolator pads while you have everything apart, because on older E36s those rubber pads are usually cooked and a fresh set will prevent knocking after reassembly. Straightforward job if you have a spring compressor and a rear subframe jack.
