good news first - was able to put together my 13" front disk brakes from Andyf today (Mercedes Rotors and longer hubs, viper calipers purchased separate) and they are a direct bolt on for magnumforce drop spindles, no washers needed

now for the bad news - I bought the 17x9 rallye rims from year one back last october, finally get the 13" disk brakes on so I throw on the rim to check my spacing and guess what, The viper calipers are too big. Not by much either. the are just touching at the ends of the caliper. I bought 17" wheels as they said it would clear the 13" disk brakes.
For future reference this kit will NOT fit the year one rallye rims

too bad that i already bought the rims, tires and center caps...will post some pics when I get the chance
