Okay. After looking over my actual log over the past 20 years or so, I have reduced the cars weight by 675 Lbs with another guesstimated 20-30 Lbs to take off with other up coming tricks while retaining a relatively STOCK look.
Only prying sharp eyes will pick up on the non stock subtleties, so there will be a Tax incurred if you want to peep under the hood for any longer than a New York minute. LOL
If budget allows and certain parts arise, I can see another honest 20-30 lbs shaved off the top while wearing an all metal skin.
