CRP Automotive U-Bolt Kits Editorial Review
The Rein HWK0004 Aluminum Bolt Kit appears to be a reliable and cost-effective alternative to OEM bolts for BMW alternators. The bolts are made of special aluminum screws and come in a set of four with a size of 8mmx86mm. Despite not being listed for Mini Cooper vehicles, they fit BMW 3 series and 128i alternators well. The bolts proved to be one-time use and lightweight. A blue nail polish is recommended to paint the heads for future reference.
