I actually did it that way and it gives it a few more lbs of seat pressure at the installed height. The reason your would remove one or the other is to be closer to the original seat pressure of around 79 or 80 lbs...I think that was what it was originally.Originally posted by scarface
Sry to get into your Question i just wanted to now if u can use the cup whit the Iternal Dampeners The way they come boxed or can that damage some thing.
Yes they will work fine with the cups. The cup makes the spring be compressed slightly more than stock original, maybe 1/16", causing you to have slightly more seat pressure, maybe 5#, but still not as high as the 100# LT1 springs that alot of vendors sell. The cups or the internal dampener is supposed to reduce revibration in the spring, using both won't hurt that I've ever heard and I've been running them that way in my car for 10k miles or more.Originally posted by scarface
Soo its ok to use CC980 with the cups and nothing will happen
internal dampener will seat against does not allow the dampener to sit squarely. it could bind the internal dampener enough to cause it to break
That's the first I've read of something negative happening with the internal dampener and I read tons of posts before I got mine, and most recommend just tossing the cups and keeping the internal dampeners in.Originally posted by Turbo86GN
Anyone else have this happen? I just changed over to 980's with internal dampener.
