Wheel Installation Tool - Porsche Center Lock Wheels - Installing those large center lock wheels on your Porsche can be very difficult to do without the inevitable wheel to brake contact. We have heard countless stories of scratched wheels, calipers and even a few chipped ceramic rotors. The only way to avoid these costly outcomes is to use a Rennline Wheel Installation Tool. Simply screw the tool into the factory threaded hub, slide the wheel over the tool and into place, then replace the tool with factory wheel nut. Rennline has also added a trick center lock style cap to protect the tools' threads during storage.
