Hello All,
I am currently in the process of refreshing my entire suspension setup on my '87 325i convertible. I have reached the point where it is time to replace the springs. I have decided to go with a bit of a more OEM+ path vs the typical H&R/Billstein combo. I live in Massachusetts, so the last thing I need is to hit a pothole the wrong way and lose my oil pan.
I have decided to go with the factory M-Tech suspension based on a 1991 325i MT2 VIN (WBABB1318MEC04986). So far, the OEM front springs (31331131330) are unavailable online or from the dealership. I have already acquired the rears (Part No. #33539057349), as those were still available. Cross-referencing that part number, I have come across various aftermarket/OEM supplier parts that match up to the factory part number. They are as follows:
- Bilstein 36-226917 OR Suplex 06024 (Seems to be the correct option)
So question number one is, do either of these parts seem correct based on the OEM part number?
Question number two is, Would it be okay to pair the Bilstein or the Suplex springs aftermarket rear springs based on the OEM part number?\ The rear springs I bought are Lesjofors 4208423 based on part #33539057349.
I know this probably seems stupid to a lot of you, but I've been trying to find answers for months, and I'm finally at the point where I need to consult the wisdom of the R3V Wizards.
Thank you in advance!
