06 Z4 M with popping sound

[Shihan70]

Hello my name is Philip. I am new here to Z4 forums. I recently purchased my 6 Z4 M Convertible with 21,000 miles on it and it has a popping sound it seems in the front end whenever I go over bumps or a driveway when theres significant tweaks with the frame. Does anybody have any experience with this and possibly advice? It doesn't occur when turning just changes in terrain suck as driveway or speed bumps or just enough of a bump on the highway or roadway. Advice?

If it's a little 'tapping' sound then it might be a loose/broken firewall brace. They're the black bars that go from the suspension turrets to the firewall below the bonnet alarm sensor.
