Hotchkis suspension

I have 3/8 between the lower arm and bump stop. Its set up for drag race with drag race torsion bars. I now want to go in a different direction. I have RMS upper control arms wilwood discs. I have heard that the RMS uppers interfere with 17 inch wheels. I also will have to start over with the brakes. I want more street some autocross and eventually track.
