PN for Swift Springs on KW Coilover Body
What's the correct part number and length for a pair of Swift 8k rear springs to go with a KW/Racecomp coil over?
Z60-203-080 seemed to be in the ball park if I ditch the helper spring. Has anyone used this shock/spring combination? |

8" is too long imho, I had an 8" 500# spring on my Bilstein and struggled to set height where I wanted in the rear, 7" 425# spring without helper was near perfect iirc and should be extremely similar to what you are looking for. 6" might need a helper spring which I think is their preferred setup.
I'd expect RCE would be able to respond to the question tomorrow if someone who has a set doesn't chime in first. |

You want 60mm ID. 6 or 7 inch length should be okay depending on where you want to set the ride height. May use helper either way with the 8 kg/mm spring rate, but definitely with a 6 inch spring.

Travel with 6" w/helper v. 7"
Is there any difference in travel between a 6 inch spring with a helper and a 7 inch spring alone?
Thanks! |

Check out the Eibach Motorsports catalog, they list a lot of information about block height and travel and you can compare spring stiffness and heights. You will see a general trend with small hiccups where the spring wire diameter increases but iirc is not listed. https://eibach.com/us/rt-2-catalog-downloads.html |

You can get more travel out of a longer spring before getting coil bind, but that assumes the damper has enough travel for that to be an issue with the shorter spring. On the KW/RCE bodies a 6" spring won't be binding, so you're fine either way.
