Front springs

[gsinnamond]

Please excuse my lack of expert knowledge.
Love cars but need help on the specs.
I recently purchased a 69 camaro with disc brakes in the front and very soft springs. The cars has cal trac suspension in the rear and seems to be lowered by inch and half. this car has a 427 big block with 500 hsp, set up for qtr mile. the front and rear wheels are 15 inch. I want to put on a protouring type of wheel and tire. I know i have to replace the front coil springs, they are some type of very soft drag type.
Can anyone reccomend a set of front coild springs to handle 17 or 18 pro touring wheels?
