The stock front leather seats weigh 36lb each without the seat tracks. I found a pair of front bucket seats from a 2001 Jeep Cherokee that weigh only 22lb each (28lb total weight saving), have the same dimensions as the stock seats, are very comfortable and have much better lateral support, and will bolt in with only minor modifications to the seat base to accept the Mustang seat tracks. I'm having mine retrimmed in half tan/half black fabric to match the rest of the interior. Should look great. I'll post some pics when they're done.
