I love my Foose wheels and I keep a set of Roush Wheels for track Events.
The only mods you will have to do with most 20"s is wear sun glasses at shows while polishing them(cromes).
If you have the Big Brake Kits with the Foose 20's you will have to run spacers for caliper clearance. I dont have the Roush Big Brake kit but I will be adding this soon(spacers too). As for brakes stock mustang GT are on for now.These clear just fine with no mods.
