If the wheels you will be using have a "normal" center section thickness (the same as the X3's OEM wheels), then you can use the original "black" factory supplied lug bolts that came on the car. If the wheel centers are thicker, you will need longer lug bolts. You must check the wheel thickness first.
All you have to do is take a OEM lug bolt off the car and stick it into one of your new wheels. then measure the length of the bolt (the threaded end) that protrudes through the wheel. If it's more than 12.5 mm , but less than 15 or so, you're good to go. If it's less then 12.5 mm you will need longer bolts. The 27mm bolts from TR are essentially "stock" length, so offer no advantage if your wheel centers are thicker than stock.
