i know that you say they will handle a .600 lift but how long do you think they will last with .595 lift?

 

Sorry for taking so long to get back with you, Ive been a busy man. From what Ive seen, theyll hold up the .595 lift, how long, I do not know though. I ran them with a cc305 cam with the lift of .544/.544 and a friend ran the same style springs with the EX 227/233 that has the lift of .565/.575, both with no problems for the short amount of time they were on both of our cars.

From what I read around here, the spring manufacturers factor in something like a .060 "buffer" for max lift. IE--When a spring advertises "good up to .600 lift", its really good to .660 with the .060 being the extra "room" needed so the spring can still handle the lift applied to it. What Im trying to say is that these srpings should be fine but again, I do not know how long they will last. Like I said in my first post, these were used for less that 1000 miles before I upgraded so they should have plenty of great life left in them. Thanks for your interest.
