you already have one of the answers: the size of your stock spring pad is
indicated by the number of exposed nubs on the spring pad. there are 5
different thicknesses for the front...1 being the thinnest.

basically you're taking a calibrated suspension and modifying it for aesthetics
and handling. much of that is subjective. you're also asking folks to make a
stab at what they feel would be successful for you with minimal information.
you really need to proceed carefully and be prepared to mix and match...
and even redo something which hasn't proven to be successful. that's the
nature of the mod game.

negative camber has little to do with size of the wheel. it has to do with the
modifications to the suspension height. aftermarket parts are needed to
correct excessive lowering (ergo undesirable camber)

cutting metal, if done improperly, can skew metallurgy and cause problems,
notwithstanding your past success with a bandsaw.

you're really reaching for answers where some trial and error is needed....
or someone who can coach you through this step by step. the course(s) of
action depend sometimes on the exact make/model of the part you select.

otherwise, it would be easy for folks to post suggestions from their keyboard
but they're not there subsidizing your purchases should the wrong call be
made.
