ANY DROP ur gona have negative camber.. especially those of u running 10.5 in the back

If i just want to keep the stock alignment specs after I drop it (less than 1 inch) will I need camber plates?

Even with the H-techs for the Z which give you the mildest drop they won't be able to align your car back into spec, at least that's true for pre 05's.

Btw I know a chick who has the same plate as your member name on her Supra
