stock 135i suspension having trouble over speed bumps?

[ichiban]

So I've notice several times that when I go over speed bumps with anything less than a complete stop before the bump and slowly rolling over, i'd hear this loud thud. I've check the underside several times as well cause the noise sounds like it could've caused some damage. I couldn't locate any damages, so I think it's just the jack points hitting the bump.

Has anyone else experienced anything like this? I've got H&R springs ready to go on, but I dont wanna have to go complete sideways just to get over these bumps.

TIA!

This will be the runflats. They cause a terrible thud over speed bumps and expansion joints in the road. The sound it makes is quite disconcerting but its just the results of having a stiff sidewall.

Digging up a really old thread....if you're still active in this community can you tell me if you ever figured this out. I have the same issue. I want to go lower but I'm not sure if my jack points will clear the speed hump in my street. Does going over at an angle do anything to help? I'm thinking it wouldn't because all 4 wheels are still on the road while the underside of the car straddles the speed bump.

On stock suspension my belly pan rub over decent sized speed bumps.
