Any problem with bigger cookies!?

[SCWDP911]

I know someone will go here, so allow me to first: ASIDE FROM A BIGGER WAISTLINE!

I do not wish to get into forged vs. cast, but would just like to know if there are any problems with widening cookies. Has anyone out there already been down this road. I would love to see some pics. I just really have always liked the look, and heck, they are usually a lot cheaper than fuchs... Any idea what the cost of something like this would be, ballpark? I would like to make the 15x7's into 16x9's and 16x8's. They would be road use only. They would be for an SC.

Thanks

It would be suprising if someone could duplicate the sandcast look to your satisfaction.
Did Porsche make a larger cookie in the dimensions you are seeking?
