depends on how aggressive your cam is

 

well in that case what is an aggresive cam ?

 

Idk but I feel like I need to change mine.. PAC 1218 with cam in sig

 

On a aggressive cam, they said about 40k or so..

 

I had 70,000 miles on 918 springs with the 212/218 .558/.563 cam... I know they "relax" but wouldn't you feel real dumb if you changed them out and then the new set broke? It seems the infant mortality rate is much higher than the old age failure rate.

 

i think the way you drive and the distance and how there broken in has a lot to do with it ....

 

I have almost 60K on my Crane springs, and I haven't been easy on them. I've seen this question brought up before, and it seems to be a HUGE gray area.

 

dont waste your money. pac spring is top of the line and your cam is mild in comparison to alot.

 

So I'm digging up this thread cause I've got 110000 on my springs. Comp 918's I believe. I've had a .581 lift cam in it for all those miles and just changed to a .596 lift. Its been rode hard and put up wet. You guys think I should change mine?
