Fellows, I have raced and weight neither car, but I have parted out both. SO I can tell you what weighs what. Exactly.
The 164 has Heavy bloody accesories. Just the rear bumper (USA) weighs 89 pounds. The front weighs only 15 pounds so I would leave be. Hood: 122. Doors weigh 137 pounds each; driver weighs 142 (go figure). Seats (front) are a whopping 65 pounds each the rear is a feather at 12 and 15 pounds.
AC and heating all together around 250 pounds.
Get rid of the 53 pound Trunk and the 97 pound sunroof, and you got yourself a kick *** race car; and screw the weight balance
The Milano on the other hand was made out of recycled Pepsi cans it feels like since everything weighs half the above values. The hood is 77. The doors I have not weighed yet but I can carry two at a time when I needed help for the bloody 164 ones.
Front bumper: 117 Rear: ?
After all was removed, the 164 could be moved by 1 person.
The Milano felt the same.
I really do think that what makes the Milano heavy is the Steel in the chassy, and the heavy De Dion, setup which, though alluminum still, covers a lot more area than the drivetrain of the 164. Think about it; the 164 has almost no weight for the rear supension. The Milano may be more balanced but it has the huge DeDion bar to cope with and the much larger transmition. (or is it my imagination?)
Bottom line: Must be nice to have an extra LS lying around collecting dust; strip it and race it Jorgen!!!
Make us proud man!!!!
Cheers
