68camaro front spring question..

[Famous68]

i already have 2 inch droped spindles installed and i have a set of hotchkiss 2inch springs i havent put on..i want to go lower than 2 but i think 4 is way to much. dose any place make a 1 inch spring so i could make a 3 inch front drop.
has anyone heard of 4inches in the front? pictures would help.
thanks
