Can someone help me determine the correct springs I'm looking for? I noticed that realoem does not have any info at all regarding springs and their part numbers.

I realize BMW springs have a two digit/letter code associated with each set (front and back) but I have no idea which ones I'm after...

LCI N20/B48 (option code 704, M Sport static suspension)

Thanks. I noticed a listing in the classifieds for a B48 w/ M Sport and they posted photos of FH and GF. There seems to be consensus on the rears being GF at least.

Most likely is FH. I have the 704 and figured it would be the same across models, but it's a b58. Makes sense the fronts are different

So this is what I've been able to confirm in regard to the 4 cylinder, M Sport springs:

2017 (B48)

Front: FH
Rear: GF


2014 (N20)

Front: FF
Rear: GD


Can anyone else with a set lying around corroborate the info above? There seems to be a bit of variance/confusion in the spring codes depending on model year and engine code. I'd like a bit more data before I feel comfortable seeking and purchasing a set for my personal vehicle.

Appreciate any and all responses.

Bump.

Would be forever grateful for someone to confirm the N20 spring codes.
