You could overinflate the tires by a few PSI too to reduce flat-spotting. Alternatively, I have these Flatstoppers...they're pricey, but a girl needs some pampering, you know.

I just found out about Fast Toys...they are a Canadian retailer based out of Winnipeg. I just bought some Rally Armor mudflaps from them for my wife's STi, and their pricing and shipping are reasonable and quick...just like a lot of US retailers...only they are Canadian so you don't have to worry about brokerage fees, duty, etc.
