Anyone in the US running AST 5100 on their M2C? Impression over stock? Also are the top strut mount for the front needed?

ast are very good.You also want camber plate to make a correct geometry. I don't know why bmw makes the rear adjustable and the front non adjustable.

IIRC default from AST is OEM compatible springs so you can re-use top mounts. As Fabri says, if you are wanting more aggressive geo then you'll need adjustable either top mounts or lower arms to add more camber. Having put longer arms on the front of my M135i (gained camber/caster/track width) and owned cars with camber plates (more NVH), I'd probably opt for adjustable lower arms. HTH, BP

I have AST5100 on my OG M2 - just fitted a few weeks ago.
Turn is much better, car is flatter into corner - the OEM suspension is too soft on the front and the far-front corner sags on turn-in - this was frustrating and didn't inspire confidence (this was the main reason I upgraded). The ride is incredibly smooth on the softer settings. I am now running @ 6 clicks (mid setting) all round and the balance between road holding and comfort is excellent. Now it has the geo done, the turn in is great, mid corner balance is incredible, but it's absolutely fine comfort wise, heck even in a straight line it feels really sorted and planted on the road - excellent suspension! The rear also has significantly more grip around corners and over road imperfections compared to stock (even in an unaligned geo state). Whether you need adjustable top mounts depends on where you drive it - I have -1.6 front (fixed) and -2.0 rear camber and this feels great on the road - (TBH, I would have liked a bit less rear camber to maximise grip (e.g. -1/-1.5), but this is how they set it up and it's fine - a reasonable balance between road and track duties - my car is lowered and apparently there are limits to how much you get the camber back to). If you are doing a lot of track days though, you should def dial in more camber which will need new top mounts. Last edited by widetyres; 06-05-2020 at 02:39 AM.. |

AFAIK setting rear toe up correctly with higher rear camber (ie -2deg++) is when it gets more difficult with the oem eccentric bolts.

None! My MINI has had major beating for 3.5 years now on this suspension, and still no issues.
On the BMW nothing as well, one bolt came loose of the control rod but we tight it again. Initial installation it was not put tight enough. MR |

I wonder how AST does in reliability stakes considering M perf coilovers do sometimes fail. |
