i know RK spring pn 22076524 is 3370 N preload. is this the highest preload spring with 27N/mm spring constant? or is the RX spring spring pn 22076526 higher preload? i dont know the preload of the RX spring. does anyone know?

also, i remember someone saying that the 90 9c1 springs pn 482086 are either higher preload or higher rate than later years. anyone know the specs? the part # must have been changed too...
