Need tech tips for lowering an 02 GT

[bjack]

I'm considering lowering my GT using the Ford Raceing "C" springs, according to the specs this should result in about an inch and some change front and back.

Should I also consider the caster and camber plates or can proper alignment be acheived without this additional cost?

Will other geometric/handling problems/concerns need to be addressed also?

I plan to do this myself, are there any "lessons learned" out there that could be passed on that would save me some time and money?

Thanks in advance!
