Places that weight savings could come from...wheels - 20 lbs, carbon fiber body pieces such as bonnet (20 lbs) and bootlid - (20 lbs), rear seat delete option - (30 lbs.?), smaller and hopefully lighter 5.5 liter DI Gen V engine block (30 lbs?), apparently the mufflers on the current car are extremely heavy so some weight can be saved there (30 lbs). I think all those add up to about 150 lbs or more in weight savings. My estimates were pretty conservative where I was unsure what the difference would be. It might be even more like 3650 or so. And that's not half bad.
Check out Doc's thread. It's all about weight loss.
