i'v been using ss springs in my barracuda and best 60 is a 1.49 foot brake. this is with a pump gas 408 and car weights 3360 with me.
i'v been contemplating going to cal-tracs with mono's,but not sure there would be much gain.
with the ss springs i left the original bands on the rear segments and added two bands to front segment both sides and that worked wonders on how my car hooked. i also use rancho's on rear and calvert 90/10 on front.
