I have a '98 LS400 and mounted 17" aftermarket wheels on the car. I selected wheels with a front wheel drive offset (catalog actually categorized these as wheels that would specifically fit a '98 LS400). When the wheels arrived, that's when the trouble began. I had to get spacers for the front wheels to clear the calipers. I also learned the difference between lug centric and hub centric wheels. The new wheels, are lug centric - the factory wheels are hub centric. No matter how I tried, I could not center the lug centric wheels on the car. For after market, do yourself a favor and mount only hub centric wheels. You can learn from my mistake and frustration. Once the tires wore out on the new wheels (and be aware, the larger wheel you go with, the shorter the tire life), I went back to the OEM wheels with upgraded rubber. They don't look as good, but man the ride is smooth.
