Does anyone know where I can find adapters or my 98 SVT, I have A Set Of 17" Roush Racing Wheel that I was gonna put on my 01 stang, but they are 5 lugs and the contour is 4 lugs so can anyone steer me on the right path???

Run a search. There's a ton of information, and if I give a summary it won't be enough: you've got to go read it all.

summary: likely not worth it. cons likely outweigh the pros. search should give the pros and cons
