After installing my Enkei PF01 I noticed vibration in the wheel. Drove a little more, and it seemed to progressively get worse. When I returned home to check them, they had become loose.

I've tightened them down more than 15 times now, it's frustrating to say the least. I've tried everything from a torque wrench, manually by feel, stepping the torque in stages. Not sure what else to do.

Is there something I'm missing here? Any advice would be greatly appreciated. Running stock wheel bolts, and correct size hub rings.

 

Do you have the right hub rings?

Edit... Are you sure they are the correct hub rings...

 

Also, are they the correct lug bolts for the Enkei’s, ball vs cone seat?

 

​​​​​​100% sure, they're clearly marked. Bought the wheels from another MINI owner (minus 1 new) who included them. I've read that the stock wheel bolts aren't compatible, but can't confirm.

 

Running the stock wheel bolts. So probably not...
I've been searching everywhere for info. Any idea where I can find them?

 

Your wheels are Enkei, different to the KONIG's I had. However, my wheels came with bolts specific to them. Maybe something to check.

 

Are you running any spacers and are they coming loose on all four wheels?

I would contact Enkei or a dealer like the Tire Rack to see if they can tell you what the correct specs are for your wheels. The stock bolts might have the wrong seat type and/or thread length.

If the factory lugbolts are correct, maybe the set you have is damaged (stretched threads??) or there’s a problem with the hubs.

Not running spacers yet, I do have them(5mm). Contacted Tire Rack, they informed me the OEM lug bolts will not work. They also don't carry any for use with spacers either. Called up ECS and they gave me two options.
