Hey guys, does anyone know of a company that can manufacture lightweight racing wheels for my exige with custom specs/offsets/weight???

I have found one here Kodiak Racing Wheels - Custom lightweight race wheels for performance and racing Kodiak racing wheels. They are three piece forged, and I'm thinking of this wheel below in all gloss black center and outer rim, the only issue is its almost the same weight as my existing wheels on the car now. Plus I would like to know if I have more choices in style and weight. They also offer a centerlock option but I have to check if I can convert my car to fit centerlock wheels or not.

Ideal size is 16" x 7" front and 17" x 8" rear

My stock wheels weigh 14 and 15 pounds so ideally would like to get lighter stronger ones for the track and autoX.

Any suggestions on other companies??? Any help appreciated. :-)
