Hi mate ,it really depends on how much she is lowered by and how low profile tires you use?
On my standard height Foz I have 16's 9J with Yokohama 215/65/R16's and there is still 3-4 inch to play with ,after measuring the diameter of the wheel and tire they are 26 inch due to them being winter ice guard.
So chances are you'll be fine depending if she been is proper slammed or not .
Good luck but going the rolled arch route can be beneficial but can crack your paint and cause rot or rust...best to get a professional to do this if you can't.
