A GT5S conversion is a lot of work, especially if you use the vendor flares which are just pieces you weld in (fortunately I have a set of factory full fenders stashed away). Conversion cost is in excess of $25K, but there's a clone 5S on eBay, been for sale for months and can't get over $100K, so a lot less work to buy someone else's investment.
My wheels are Kodiak, not a 10 spoke campi pattern.
