Quick question regarding coilover preload

I recently installed fortune auto coilovers. Every so often I hear the spring shift like it was on a bind. Would that mean I have to much pre load or not enough?

Please note that separate adjusters rarely if ever actually result in a change in the pre-load, regardless of what people call these systems. In truth, the separate adjusters are used to set ride height and how much of the total travel is available for bump vs rebound separately. The springs are under a pre-load that exactly matches the sprung corner-weight in 99% of the set-ups because no one is silly enough to have zero available rebound travel at static ride height.

In short, pre-load isn't the issue.

Does the system have helper springs?

No it doesn't. And I'm hoping it won't hurt if say there is a half inch more preload than stated to do in the instructions?

From what Fortune says it's because of the type suspension we have. They offer roller bearings to solve this problem. I have them and don't hear any spring bind.

Recently only available on race applications and mega-dollar suspension systems, Fortune Auto now makes spring noise and spring "twang" a thing of the past. Needle Thrust Roller Bearings are essential for noise-free operation on vehicles with front strut configurations. Vehicles with front struts tend to turn the front springs on coilover applications. This results in the spring dragging on the spring perches and making an annoying "boing" or "twang" sound. This sound is harmless but can get annoying at times. This noise is more prevelant in low speed occurances such as turning into a parking spot or when temperatures are below 60 degrees Fahrenheit. We have also noticed that heavier cars benefit greatly from this solution (Evolutions & WRX/STi platforms.)

Fortune Auto now offers a solution to this common problem! Bearings come in a set of 4 for the front struts (with 8 thrust washer plates). The washer plates sandwich the roller bearings and sit at both ends of the spring / spring perch. This offers silky smooth operation and is truly a noise-free solution for any 60mm ID coilover! Our roller bearings are designed to be lubricated with white lithium grease before install. These bearings can also be installed at our facility on all new coilover purchases.
