what is the maximum wheel width i can use on the back of my LCR? i'm toying with the idea of getting some of these http://cgi.ebay.co.uk/PORSCHE-911-9...0100684471QQcategoryZ9888QQrdZ1QQcmdZViewItem i know i'll need adapters to change it from 5x130 to 5x100. would 10j and the width of the adapters be too much? does anywhere make/sell replicas so i can get a set of four in 8x18 instead of 8x18 on the front and 10x18 on the rear? personally i think it will look awesome!
