First, I'd do like BJ suggested, and adjust your steering stops and see what you can put up with. If not, then spacers are acceptable, IF...1.

1. Use a quality brand name spacer. SpiderTrax are good ones.

2. Use a spacer that is machined, not cast.

3. Use a spacer that has full-length wheel lugs integral with the spacer.

4. Follow the spacer manufacturer's instructions re torque.

5. Use LockTite on the nuts holding the spacer on.

6. Recheck the torque after 50-100 miles of driving. Re-check torque again about twice a year -- I check mine when I service the wheel bearings front and rear.
