those are pretty good springs....common belief for 918s was to change them between 20k-30k miles....at least thats what some of the guys i know do

It really depends on a bunch of different variables. Highway or city miles? A lot of High rpm or rarely? How long do you warm up the car? I would say to pull a spring at 20K or 25K and check the pressure. If theyre good, put it back in. 5K later pull a different spring and test again. Lather, rinse, repeat.

sounds good, thats wht ill do......as far as all that, i do warm the car up before i drive it, and i rev it high from time to time.....Ive had them in there for about 4-5k miles

I ran a set of PRC duals for 43,000 miles and they were still good when I took them out. The cam was 233 duration with .595 lift. They are a very good quality spring.
