1st Gen R53 Cooper S Weird chink noise in the front

So for the longest time I've noticed I have a weird chink noise in the front end whenever I hit abrupt bumps.I can best describe it as sounding similar to slapping two quarters together. I know the control arm bushings and the swaybar bushings are fine as I changed them back in February to the powerflex ones. The car doesn't drive funny at all feels very smooth during hard cornering unless there's fast bumps (to be expected though bumps seem to throw MINI's around) Should I be concerned with this noise? or is this a sign of something going bad?

 

Those are good too... I recently had a failed attempt at installing some M7 coilovers (tires were scrubbing) the strut tops looked perfect. The noise was there before I played with the struts so reassembly shouldn't be an issue here either. I had a similar noise on one of my 240's before it ended up being the sway bar end links but the ones on the MINI look fine.

oh and I thought of another way to describe the noise its almost like a loose bolt with a washer on it sound. I have been chasing this for some time now. Finally decided to see if anyone else has had similar noises.

 

Engine mounts are definitely good I changed them last week my upper spewed it's guts. The axels appeared to be in good shape earlier this year when I changed my clutch... I should have mentioned I've had the car borderline completely disassembled this past year. The noise was there in the beginning and still persists now. But the only time I really hear it is pulling into the drive way, there's a 2 inch or so lip where the concrete meets the asphalt and depending how fast I pull in determines if it makes a sound or not.

I'll be doing my oil change this weekend I might try to check the sway bar endlinks again. I'll also take a closer look at the axels. Keep the ideas coming though.

 

Well I found the source of the noise I've been hearing. It was actually a completely unlikely suspect... It's my front bumper. While doing my oil change I decided lets hit the wheels and see if I can replicate the sound and I did. It wasn't till I moved to the driver side that I noticed the sound coming from the bumper. If I push on the bumper and hit the wheel I wasn't able to get any sound. Guess I'll be looking that over when I play with my lower grill again must have a loose bolt or something in there.

 

I'm just happy that it wasn't anything more serious I already have enough NVH from my engine mounts whats a little bumper noise lol

 

or maybe a cha chinger after all it sounds like change smacking together... It's my MINI's way of letting me know its raping my wallet if I like it or not lol.
