SD350Z

I took my Z into the dealer for service and a brake inspection. 5% left on the front and 90% left on the rear. This seems like an uneven ratio of wear (I figured the numbers would be more like 5% front 50% rear). Oh, and the car only has 20,764 miles on it. Anyone else have similar experiences? The car is also getting new front tires put on it, since the inside tread blocks were completey bald due to Nissan's wonderful factory alignment job (if you have less than 30k on your car, talk to your dealer about this as it could get you a set of free tires under warranty!). I thought the excessive tire wear and brake wear might be related. Any thoughts?
