I'm already planning a diet on my Camaro many weeks ahead of her arrival...
 

Hi, finally the new Camaro 2014 will be imported to this disgraceful land of (motoring) oblivion, unfortunately not the ZL1 or the Z/28 models though...

I'll be probably getting the manual SS to which I hope to drop a few hundreds lbs, starting from the wheels.

There is a company in UK that made me a set of ultralight race wheels for my C3 Vette a few years ago, I've never seen anything like these ones and together with the DOT Hoosiers each wheel weights just a share of the Vette's OEM.

Could you please give me full details of the sizes, offsets, etc of the new Camaro wheels to pass them to the wheels builder?

I'll appreciate that.

18 & 19" have 38mm Offset, 20" wheels have 35mm front, 40mm rear

If you can get a 1LE over there that would probably be your best bet. The wheels and tires alone can be sold for about the cost of the package. Good luck!

Unfortunately there won't be any special Camaro model imported over here, only the SS manual...

There are several good weight threads, check these for starters!
