Well I'm currently at the other end of the spectrum
The stock springs are much taller and wider. I almost thought I had the wrong set. The old springs stuck out of the box that the new springs came in.
Didn't need to compress the new springs upon install. They were much shorter and narrower. Not as wide as stock
Car sits beautiful IMO
Also , NO vibration from the axles with billet dog bones and and poly bushings.
However, I did use my Billet end links. What a difference. They are much shorter and have a solid billet core, about a 1/2" thick. I had to jack up the control arm just to get it to fit. I use the Energy Suspension poly bushings too
With the car on the ground, it sits amazingly nice for 16" wheels. Its an awesome touch for the gmpp suspension (front sway bar, rear sway bar , front and rear strut tower bars with aluminum brackets and solid trailing arms)
anti-pogo washers are a MUST for all 4 corners. A quick push down on the car and you see the stock washers moving. So I borrowed a buddies cradle bolt washers while he was doing his engine build (anti pogo washers) and it tightened it right up
A quick drive, about 5 miles, proves to have a stock ride feel, but firm. My stock springs seemed too soft/squishy. These give it a firm yet soft ride. I can take turns without the car swaying or dipping. Its night and day difference.
The eclipse has Tein springs and Tokico struts and that hard/solid ride. So compared to that, I think I lucked out and found the right combo.
I like them so far. Lets see how long or well they hold up. I drive a ton, so Ill be a good tester lol
