make sure you have the steering and everything hooked up when your doing some of your mock ups. too much droop can cause bumpsteer. you also have to check tierod geometry, for angles and bindage when turning in full droop and full compression. put the front end together with the tires and get your bottom out set, thats a critical value, once you have that set you can work on droop untill you run into bindage or bumpsteer.
