Steeda Progressive Spring review

[Bankss550]

Good idea. I helped a friend install last week, and we moved them to clear for the spring compressor we were using. I'm sure others did the same. I can't recall if we moved them back to the original position, but no noise so far is a good sign.

I'm pretty sure we did :cheers:

After I went through all this noise locating and installing the isolaters, I noticed my daughters '15 Escape has progressive springs on the rear also with isolaters. From the factory.

Quick pic with the new wheels and steeda springs.

It has been several days since the install ... how is the ride quality - would love to hear your feedback.

Best Regards,

Great pic!

Tech info on Steeda Progressive springs:

145/225 lbs/in front

525/820 lbs/in rear

From curb to 1/8 inch compression the rate increases to 225 lbs/in front and 820 lbs/in rear.

With that being said, when in roll the rebound side has less force pushing up, therefore producing less chassis roll and improving ride quality.

There will be less force variation per inch of rebound in the 'soft' range of a dual-rate spring (going from soft to firm in only 1/8" travel is pretty sharp progression - essentially they're dual-rate springs). But rebound displacement is dependent on lateral load transfer off of the rebound-side suspensions, and that depends on lateral g's. Extension in rebound travel is not the independent variable here, force removed is.

A fixed amount of LLT (from any given cornering g-level) will make a softer spring extend more rather than less, so I see roll increasing slightly rather than decreasing (plus a small net increase in ride height). Consequence of force equilibrium.

I suppose the sta-bars do get worked a little harder to hold roll down, but without changing them or their stiffness adjustments I don't see these fully compensating for the softer rebound springing on the inboard side either.


That said, I'm pretty sure that they would ride better, certainly for as long as they're operating above static ride height and the stiffer bump direction is stiff enough to keep the car off the bump stops most of the time.

Would love to hear some feedback/ideas on this:

- My v6 had steeda progressives with stock shocks/struts for a year - no issues until recently (last 4 weeks)
- Upon any amount of weight transfer on the front right tire (turning left), there would be a rubbing sound like tire tread hitting something...best way to describe it is inserting something into bike spokes, but in my case it's tire tread (especially on my winter set with more aggressive tread)
- Checked the wheel well - there are no rubbing marks
- Sounds continues to occur after wheel/tire swap and gets progressively worse
- Return the car back to stock (trade in) - the sound is gone
- Tried to reproduce the sound the same way I could before to no avail

So it seems like something with the springs up in the front caused this issue. I am not mechanically inclined at all, so I wouldn't even know where to begin, but the reason I'm asking is I just bought Steeda pro-action struts/shocks and will be re-using my springs. Should I be worried or check anything? Is there anything I need to do?

Thanks

You should be just fine. pm me a picture of your springs to make sure they are not compromised. If their is any discrepancy Steeda will address the issue.

Thank you,

Really want these springs but am concerned how much more I'll be scraping. I already scrape so much with the Cervini's chin spoiler at stock height.

I have the Steeda Progressive springs and Cervini's chin spoiler. I've only had 1 place that I scrape, that's pulling out of the gas station that I always go to which is on a steep hill. When I get to the bottom of the hill it's a sharp transition to a flat road. I just go slow and it barely scrapes on the bottom of the chin. The first couple times I was worried and inspected it closely. Now I've done it >100 times and I can only see it from under the car and it doesn't seem to be hurting anything. I've never had it scrape anywhere else. If I really cared, I could get the Steeda spring spacers and raise it a little but I don't want it any higher.

If you scrape now, you will scrape more with the progressives, with any other lowering spring honestly. Law of physics

Progressives are a very aggressive drop up front. I want to add a splitter myself, but stalling because of the low drop. Becoming less concerned about scraping the bottom, can't see it anyway

I'd like to keep the factory alignment specs after I install the Progressive springs. Will I just need front camber bolts and thats all?

 

[Norm Peterson]

I'd take a "wait and see" approach here.

"Factory specs" is actually a range of acceptable values. You may still be well within that range, in which case nothing need be done beyond checking/resetting toe.

If not, there are much better approaches to correcting camber than reduced-diameter bolts that can only be torqued down to about half of the factory spec for the full-diameter OE bolts.

Mine went back to factory alignment specs without anything else but a good alignment mechanic.
