Did a quick search of "roller bearings frs", because I had no idea what those were. And this is the description this product has on replacing the roller bearings on our car:
This upgrade is for 2 sets of bearings that will go on the front struts.
Recently only available on race applications and mega dollar suspension systems. Fortune Auto now makes spring noise and spring; 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.)
