5 bolt strut mount on 3 bolt F30s

SlowF30 · 12-21-2019, 04:30 PM

Does anyone know if Corteco 31306881930 5 bolt strut mounts are ok to use on a 3 bolt f30? I know FCP Euro use to say to use 31306869931 hex bolt with washer but when I checked their site today, this strut mount was removed from available strut mounts for the 2013 sedan. I'm in the middle of assembling my front struts and would rather use the zero mile 5 bolt strut mounts instead of the used mounts that have over 50K miles.

Thanks in advance.

In case anyone ever has the same question. FCP Euro confirmed it's not recommended to use the 5 bolt mounts on a 3 bolt car. My guess is because the 5 bolt use a m8 and the 3 bolt use a m10.

Did you ever consider its not recomended to use 5 bolt mounts on a 3 bolt mount car because of the lack or holes in the car body work (only 3 instead of 5) and even the existing 3 holes being in the wrong position to line with holes in the 5 bolt mount. Look under your hood that should provide the obvious answer.

I put a 3 bolt mount side by side with a 5 bolt and was able to get 3 of the holes to line up. This was with the mounts in the same orientation. If it was an obvious answer I wouldn't of asked the question in the first place. Either way, I'm returning the 5 bolt for the correct 3 bolt. People have used 3 bolt mounts on 5 bolt cars.
