If you don't know how to comfortably build front suspension, you should start with a clip for this frame and go from there. After you've built a frame, and seen how the front suspension works, read up on suspension design. There is a lot to it. You have to take into account your arm geometry and how it will affect camber and castor. Also your steering has to be setup correctly to get minimal toe in or out, and to get correct ackerman.
