Which BMWPS to go with Bilstein B8?

How do I find which part number for the BMWPS to get for my specific car with the bilstein b8? I’ve heard this set up is a good middle ground of comfort and performance without a huge drop compared to the m sport springs

BMW performance springs are 10mm lower than sport.

You don't need B8 with them. FSD would be ideal.

Recommended BMWP springs are based on your car's weight. Is your car AT? Is it heavily optioned eg Nav, power seats, etc.

128i or 135i? Auto/manual/sunroof?

If you have a 128i, I'll be selling my complete setup soon. They are for a 128i and have the Koni Oranges installed.

Thank you though

Sorry, those are the part numbers for the springs that should work with your car.

I have lighter springs on my vehicle since it's a 128i.

31 33 6 788 893 is for the T3 front springs.

33 53 6 788 899 is for the heavier rear springs.

My 128i uses 33 53 6 788 898 in the rear and 31 33 6 788 891 up front.
