Which one offers better handling? The FE2 swaybars? or the FE3? Or are they the same and FE3 uses different springs?

Only two, FE1 and everythign else. It'* FE1 FE2 and F41 in Bvilles.

Seth, the swaybars are the same, springs are different. Each 'F' class may have as many as 5 different rates for springs as well. It'* more of a RANGE of stiffness, rather than a single spring rate.

Also, you can't mix and match springs from different cars, even if they're all the same RPO. For the reason I mentioned above. They're computer-matched sets.

Yup. The only way to know what range you have is to mic them, It gets boring quickly.

FE3 as I know it is a Buick thing.

I saw a car ( cutty or a 2 door regal i think) with an FE3 badge tonight....
