The ones photographed by M50 in his post above are the correct strut covers for M2C/M3/M4 - all the same part # I believe. These are the ones I have installed on my car and they cover the whole strut top incl. M3/M4 reinforcement rings I've retrofitted. BP

So i've just ordered new versions of what came in my car anyway?!
x1- Left engine hood/topmount sealing: 51767307863 x1- Right engine hood/topmount sealing: 51767307864 is what I ordered My steel braces are now out and to be honest the car feels better without them. I think with them the front end is too rigid. The car seems really fluid now and is a joy to drive just around town. I can see why BMW didn't kill themselves to get the braces altered to fit on the M2C, it doesn't need it/is better without. For the time being mine are staying out. |

Or it's simpler than that and you just remove the yellow cover then the strut tower cover just pops off. Doesn't look hard at all either way. |

Thanks I'll get some ordered.
In day to day driving I feel more confident in placing the car, it's just a bit sharper. Even applying throttle something seems different for the better, maybe I'm full on hallucinating now Don't miss the front steel braces, I think it's genuinely better without them so don't fret about making it work together. |

Retrofitting M4 rubber strut top covers is easy with everything else in situ.....

The garage did cut them yes.
The more I drive with the brace in situ the more delighted I am with the car now it's making me smile. The car makes sense now and agree with the usual 'should have come from factory' sentiments echoed on here. Last edited by 3t3p; 02-16-2020 at 09:28 AM.. |

I'm starting the process of preparing to do this mod, and have gathered all of the parts I need from the various locations including this thread, the one linked previously, and a guy in South Korea on the F30 forum that retrofitted his 4 series. I also went through each relevant section of RealOEM for the M4, M2C and OG M2 and compared parts from each section for duplicates, and then went through the removal and installation procedure in ISTA+ for the torque settings and replacement requirements.
I thought it might be worth sharing this full parts list on here because there are some parts which aren't needed for the M2, and some which are different between the M4 and M2C. To aid in copy and pasting, I'm going to use fixed width font to create a table (and what a bitch that was to get everything lined up; forum software doesn't let you use more than 1 space at a time!) because a table would end up as an image and couldn't be copied from. I'm fairly confident that this is correct, but feel free to comment if I've missed anything or made any mistakes. I can always go back and edit the post if need be. The first point of confusion is that the M2 has 5 M8 bolt strut towers, and early M3 and M4 models had 3 M10 bolt towers. This results in different reinforcing rings, strut top hats and strut braces. The next point of confusion is right and left hand drive. Many of the forum posts were from UK based owners and their part numbers are sometimes different. I'm actually British myself (shout out to my homies!), but am based in the US, so all of the parts listed here are for an OG US M2; LCI in my case, but I don't think that makes a difference. So without further ado, here is the list: Description | BMW Description | Part Number | Qty Needed | Notes - Strut Reinforcement - (Optional, and not on M2C) Strut reinforcement | Reinforcement for support bearing, left | 31302361991 | 1 | Strut reinforcement | Reinforcement for support bearing, right | 31302361992 | 1 | Longer screws for reinforcement plate | Hex screw (M8X33 10.9 ZNS3) | 31307855400 | 10 | Renew 30 Nm + 90 Degrees - Aluminum Strut Brace - Aluminum strut brace | Strut brace | 31127855855 | 1 | Aluminum brace to strut top bolt | Torx screw with collar (ASA M8X30) | 31106859809 | 6 | 28 Nm Aluminum brace to fender top bolt | Torx screw with collar (M10X30-PC-10.9) | 33326796225 | 2 | 34 Nm Aluminum brace to bulkhead bolt | Hex bolt with washer (M10X25-10.9) | 31106854219 | 2 | Renew 56Nm + 90 Degrees Rivnut for top of fender | Blind rivet nut, flat headed (M10) | 51718065070 | 2 | Strut top hat for M2C brace | Guide support | 31307853702 | 2 | Strut top nut | Nut, self-locking (M14X1,5-05 ZNS3 | 34339806226 | 2 | Renew 71 Nm Sway bar drop link nut | Hexagon nut with collar | 33326768884 | 2 | Renew 56 Nm - Carbon CFRP Brace - CFRP U shaped brace | Strut, CFRP, front end | 51618061631 | 1 | CFRP to aluminum brace bolt | Hex bolt with washer (M8X32-ZNS3) | 11287839136 | 4 | Renew 28Nm CFRP brace to front | Hex bolt with washer (M8X22-8.8-ZNS3) | 22326760945 | 2 | Renew 28Nm - Plastic Trim - Rubber strut top cover | Left engine hood sealing | 51768066661 | 1 | Rubber strut top cover | Right engine hood sealing | 51768066662 | 1 | Top of fender to hood plastic | Sealing side panel, left | 51768073533 | 1 | Top of fender to hood plastic | Sealing side panel, right | 51768073534 | 1 | Under window plastic cowl | Cowl panel cover, Part 1 | 51718073545 | 1 | Right bulkead cover | Cowl panel cover, Part 2 | 51718059699 | 1 | Left bulkhead cover | Cover for units compartment | 64318059697 | 1 | Plastic rivet clips | Expanding Rivet | 51118174185 | 8 | - To return to stock - Strut brace to strut top | Torx screw with collar (ASA M10X20) | 07147270121 | 2 | Renew 56 Nm + 90 Degrees Strut brace to bulkhead bolt | Hex bolt with washer (M10X25-10.9) | 31106854219 | 2 | Renew 56 Nm + 90 Degrees Strut top nut | Nut, self-locking (M14X1,5-05 ZNS3 | 34339806226 | 2 | Renew 71 Nm Shorter screws w/o reinforcement | Hex screws (M8X30-10.9) | 31306869931 | 10 | Renew 30 Nm + 90 Degrees One thing to note if you choose not to do the reinforcement, or if you choose to do reinforcement separately and before you do the Aluminum strut brace, is that the top hat securing bolts and shock top nut are single use, and you'll need to replace these each time you change the suspension top hat.

Oh, I forgot to say, some posts had suggested that the part, "Partition, equipment area, top - 51758061866" might be needed. This is indeed different between the OG M2 and the M2C, with the M2C sharing the part with the M3 and M4, but I think the difference may be related to the S55 vs N55, and the parts appear to be identical except for a missing bolt hole on the M2C / M3 / M4 version that we have on the OG M2.
I have therefore come to the conclusion that we don't need to buy this part to do the retrofit, and if you were to buy it, it wouldn't fit correctly. Again, please correct me if I'm wrong.

According to realoem, these 3 parts already exist on the M2... therefore are not needed? 51768073533 51768073534 51718073545 |

Let me check again, it could very well be that I’ve put the wrong thing there. I think they are different between the OG M2 and the M2C / M3 / M4. It would be great if we don’t need them, but it’s more likely I put the wrong party numbers.

So sadly, we do need these parts. The details are that 51718073545 is the plastic at the bottom of the windshield, which is required if you want the M2C / M3 / M4 side panels to fit correctly. 51768073533 & 4 are the plastic seals at the top of the fenders that are slightly different to clear the larger aluminium strut brace.

Did the aluminium / strut top hats / reinforcement rings last night. Was a really quite easy job and took 2.5 hours start to finish.
I put the car up on the lower height of the quickjack, and used a trolley jack to lift each side, remove the strut top nut and slowly lower everything down. Un-bolted the stock top hats from the body, cleaned up the seam sealant so that the reinforcement rings seated flat, then put it all back together. Aligning the shock through the top hat requires you to push the whole shock whilst jacking. I did this on my own (wife was asleep), but it would be far easier if you had a helper. The difference to steering feedback is impressive, as is the increase in ride comfort. I guess the body was doing some of the suspension work previously, and that's all undamped. I'm running the stock suspension rather than upgraded, and I'm impressed with the improvement.
