Woot! I finally found a copy of the pre-production GXP wheels in Chrome! I found the Mille Miglia EVO 5'* - but they only come in bright silver much like the stock production GXP wheels. Not enough difference between the two wheels to go through the hassle and expense of switching them out. They were only going to be about $1,300 shipped though plus installation.
The chromed wheels I came across are made by ZNA Alloy Wheels and are available at Pep Boys of all places. They are an exact duplicate of the pre-production GXP wheel but Chromed rather than polished. I have seen them in person and they look very nice and the price is flat-out unbelievable! A full set of 18'* are... (drum roll) $599!
No, that is not a typo - $599.00 Woot!
Just wanted to give you guys a heads up. I am writing my letter to Santa right after I finish this...Ha!
