I did the lightweight battery installation today (see Lightweight Battery). My actual weight savings, including terminal adapters and all mounting hardware, was 36 lb. Total cost, including battery, terminal adapters, and mounting hardware, was about $100. So, for $100, you can reduce your Cayman's weight by about 1.2%, with a commensurate gain in acceleration, braking, and cornering. You can't beat this mod for cost-effectiveness!!

The battery idea sound like a real winner! I think I will try it.
But every time I look at this fun thread, I wonder at what point have we just made the Porsche version of the Ariel Atom? LOL!
If you install a Motorsports Vapor Oil Separator (VOS), you have to do something about the air injection pump that is in the way. Either the pump must be hacked into with a saw or grinder to provide clearance for the Motorsports VOS, and then the hole patched; or else the pump can be removed. The pump's only purpose is to inject additional air into the intake ports during the first few minutes of operation to help the secondary catalysts in the exhaust manifold warm up faster. If one chooses to remove the pump, you'll save 2.5 lbs. No CEL will come on if you have the latest flash from Softronics. I don't know if you'll get a CEL or not with the stock flash.

Those are so much smaller than the old 996 ones and probably weight half as much Smog guys won't like it but... they can't see it's gone either

Removing sprung weight, one pound, is like removing 4 pounds of unsprung weight. Buy magnesium wheels and carbon brakes. Use lightweight racing tires. Enjoying better braking and handling.
Uhhhhh.... isn't that backwards?? Unsprung weight is stuff like wheels and brakes (not riding on the springs). Unsprung weight reduction has the extra benefit, not sprung weight.
