I have installed a number of American Racing model AR95T77545 wheels with 225/55-17 XL tires with exceptional results. These wheels are 25mm offset and fit perfectly on both Syncros and 2WD. They can use stock alloy lug nuts/bolts as long as you have thin wall sockets. Tuner spline nuts/bolts work real nice. These are also rated for 2,200 pounds/wheel.

This line caught my eye;" What's immediately apparent from the results is that as the wheel-and-tire packages get larger and heavier, acceleration and fuel economy suffer. Neither is a huge surprise, but we measured a 10-percent drop in fuel economy and a four-percent degradation in 0-to-60-mph acceleration from the 15s to the 19s". I looked at these this morning. http://winstonsalem.craigslist.org/pts/2618213904.html . Nice looking BIG wheels. Some road rash. He also has the longer lug bolts. The bolt hole size is good but it appears the center bore (~57mm) would need to be opened up. I need to actualy take a front wheel off my truck and do some measuring . I have read the grease cap can be shortened to get rid of the lip. I arrived at a back spacing of 137.25mm on the Audi wheels . By my calculations I would need a 14mm spacer? Anyone? Thanks Ken
