Coil springs that lower 96 Cobra no more than 1"?

I don't want my car in the weeds and would like a slightly stiffer progressive rate spring for my 96 Cobra. I did a search on this site and didn't see anything helpful. I thought I had read that late model Mach I springs would fit the bill. Anyone know for sure?

Thanks fellas!

oooh, I see you can use spacers to adjust ride hight. Nevermind
