E90 Too Low on Eibachs? Bottoming Out Big Bumps
I bought my car with the suspension already installed but I believe the bump stops were cut at least up front. Otherwise the car has 95k miles, maybe 40k on the suspension which is Koni yellows + Eibachs. I don't drive the car that much and for the most part the car handles and drives great. However there are a handful of potholes and dips on the highways around me that will cause me to bottom out really hard.
It seems like it is too low and the wheels are fairly sunken under the fenders. I do have spacers and wider wheels but even when I took off the spacers I was still sunk in the wheel well so it seems like a ride height problem. I have been considering going back to stock sport springs or something but we don't have many alternatives. It seems Eibachs are a popular option for the E90 but I would expect to see more complaints if the springs were the problem. I found a few threads that mentioned using an E36 top hats to raise the car a little bit but it seems a little unnecessary. Should I just refresh the top hats? Are there any other wear items that would reduce ride height? What about bump stops, should they have been cut? |

Your suspension mod is common on the E9X and I've never heard of bottoming issues. But if you suspect your bump stops have been tampered with, that would be my first port of call.

Eibach springs are terrible, even though they're common and many people are happy with them. Get BMW performance springs - similar stance, but with improved rates.

I did eibach springs and B4S. The car was sat hard on the stock bump stops at rest. Poor! Fitted E30 spring hats and rubbers and mini (bmw) bump stops and it now actually has shock travel. I trimmed rear bump stops. 2010 E91 325d |
