How did they wear? Was it even, or did you have inside edge wear? If so, you may have excess negative camber on the front wheels as did I. Camber kits and reducing the negative camber did wonders for it.
Also, the best wearing tires I've had on my 98 SVT EO are Dayton Daytona ZR tires. Dayton is a Bridbestone brand, as is Firestone and Fuzion. The Daytona ZR resembles a Bridgestone 750 as well as the Fuzion Zi. The last set of Daytona ZRs lasted 60,000 miles on my car.
