    KONI Struts E36 (M3/328is) part numbers confusion

    Ok, so I understand that the fronts are always a different part number from the rears because they are obviously different parts.

    What I don't understand is why there are to be two different part numbers for seemingly the same front struts. What is the difference between the two??

    The part numbers in question are:

    8741-1272 Sport

    and

    8641-1372 Sport

    Here's a link to the results that show both options when I enter my car info (1997 328is) on the KONI site:
    KONI Struts for 1997 BMW 3-Series


    The 8741-1272 option is more expensive and appears to be only for the 3-series, rather than the M3, whereas the 8641-1372 seem to only be for the M3.
    My confusion is that I thought the struts for the E36 M3 were interchangeable with all E36 3-series. Am I wrong? If so, what is the difference?

    My goal is to upgrade my suspension to get better handling for street driving. I don't need coilovers. I just want a quality set of Konis with either H&R Sport Springs or H&R OE Sport Springs. I realize I'm asking alot here, but which part number should I go with for the KONI fronts? I've already bought the rear KONI 8240-1115 Sport Struts and just need the fronts. All other advice on suspension upgrades will be appreciated, but I'd like to focus on the struts here.

    Thank you!

    M3 are inserts, i believe the 328 is the whole strut

    That would explain the price difference, but I don't understand why anyone would want to use the inserts. Just doesn't make sense to me. Thank you for the reply.

    m3 has sway bar tabs on the shocks, 328 has them mounted on the control arms

    An insert is less expensive to manufacture than a whole strut. Why the non-M variants are full struts is a mystery. I'd prefer the M units to be full struts as well. Go Bilstein.
