i picked up a set of function form coilovers finally. my only issue was that they werent the exact rate i was looking for for the track.

now my question is...

do most full bodied coilovers use a "standard" spring size so that i could measure and get something from swift for track use?

and maybe get the skunk2 launch springs to use in the 1/4?

unfortunately my knowledge base is in the engine department not suspension.

thanks for any help.

 

Should be able to use any standard coilover spring as long as the ID is the same. Eibach ERS springs are available in both 2.5" and 2.25" inside diameter. I'm sure Swift is the same. Just measure what diameter springs your suspension came with.

 

F2's ID is 2.5". The length of the spring is either 7" or 8" depending on the application.

I would not recommend a drag spring because the rate my overwhelm the damper and blow it. Not to mention it might void your 1 year warranty from F2 since you aren't using their springs. They can provide you with their custom rate springs for about $50 IIRC
