Losing 20 lbs around the middle would do the same thing and you get the benefit of potentially living longer. Alloy heads can't do that.  |
So for you 40 pounds is not a lot. I don't think the OP is shopping Kirkhams. How else do you save 40 pounds on a Superformance? Yea if you are carrying extra weight lose it I get that.
