just seen eibach released a progressive 5th coil spring. With a 250lb primary spring rate to a 425 secondary rate overall 10in spring. Is something similar to what advanced does with there 5th coil build?

nothing new here, afco has done this for years, and i believe advanced does a digressive deal, meaning softer rate as it gets compressedQuote:

Like Grt said, not new whatsoever.. this has been out for atleast 10 years, and they had other ones before..

I'm still trying to figure out how progressive and digressive can both be right. My many tests of progressive systems have all been abysmal failures. I've honestly never run a digressive setup.
Well according to 20 year old chassis setup guide, stiffer 5th coil spring = more instant traction and softer 5th coil = more delayed traction... so obviously digressive spring = more traction ALL THE TIMEQuote:

How did you set that up?

This is a crate motor car. I believe there's a lot of traction to be had in the fifth arm area people just don't look at. Hoping to get on a pull down rig this month and play with that.
I have like 5 of themQuote:
