Default Spring choices!

I finally decided to be smart and put 1.6RR on my car, I'm returning the 1.5's for an exchange so that is handled, my cam lifts to 612 and I currently have PAC 1220's?? (Don't hold me to that number) but I remember that they only lift to 600. What options do I have for 612+? Thanks!

Sounds like you need to upgrade your springs. Something with a max lift of .650 at minimum. There is a PAC 1220X that will handle up too a .650. Is the .612 lift you mention with a 1.6 rocker?

Personally, I wouldn't use anything but Comp...and never a beehive spring...that's just me though.

PAC 1518s are good to .650 and were pretty popular for awhile. The partriot gold extremes are a double spring good to .650 that are also a solid choice.

Lots of choices, just depends on what type of lifters you are running how much RPM you want to turn and if you ever think you will put larger valves/more lift in the car in the future.
