First Look: 2015 Steeda Mustang Lowering Springs (Installed)

[Ryan1112]

How will these change suspension geometry? On my S197 I had to use the X5 ball joints to get the camber curve corrected from lowering. Then rear control arm relocation brackets to regain traction. The stock shocks just weren't enough for the higher spring rates so then came koni shocks and struts. Not to mention the bump steer kit to correct the bump steer caused by the ball joints.

I have to admit though after installing all that I started winning autocrosses.

What is the actual curb clearance on the front with these on? 7" instead of the regular 8" or does it pitch the car down so you lose more on the front end?

Noob question but how is the ride quality with lowering springs? I know they say there no loss in ride quality but is that true.

I would like to know this as well. Never lowered a car before.

From my experience it'll be ok for awhile on stock shocks. Lowering springs will wear your shocks out faster. How much faster depends on your driving style and roads

Your Steeda site says the springs are for GT. Will you be coming out with an EcoBoost model?

Absolutely, there will be a version for the EcoBoost as well. This is one of several test vehicles - Comp. Orange ftw!

We will have parts coming in the near future to fine-tune the adjustment, although there aren’t any negative affects with lowering it one inch as-is - it won't disrupt the suspension geometry. Also, bumpsteer kits are one of the products coming soon.

David,

This morning I was chatting with someone on your site about these springs and got an interesting answer. I was asking specifics about these versus the stock GT Perf. Pack springs and the person I was connected to told me that they would work, but he recommended waiting "a couple weeks to a month" as there was another version coming. He said he couldn't say more about it, but said that I "would not regret the wait".

Can you expand on this? Was he mis-informed, or is another version of spring for for the GT cars coming?

Interested in the answer to this as I'm looking to pick up a set!

Once those springs settle they will be at the perfect height.

Very, VERY sexy!!!!!!!

It looks like the sport springs are coming first which will work for most drivers but they will likely have some more racing variety springs and spring and adjustable shock sets coming soon since they will want to race their products. I've used Steeda ultra light springs in two cars, a little stiff for road driving, but awesome on the track. Not bad for the strip either when used with adjustable shocks.

Hi guys, sorry for the delayed response as we've been prepping for SEMA this week. There will indeed be two versions of Steeda lowering springs for the S550, we will update you on the second version as soon as it's available!

 

[HalfMoon]

Thanks for the response. Holding on as long as I can, but I have this burning credit card in my wallet making it uncomfortable.

Yeah, makes sense, but the track lap with Randy Pobst, has him complaining the stock PP suspension was under-damped, if I'm not mistaken.
Adding another 25% stiffer springs, is only going to make that worse.
Although, I doubt I will ever push my car as hard as Randy did, and if I do start doing more track events, I most likely will be looking at a full coil-over set.

This is a very important question, i would like to know where the 25% number came from and if any shock dyno's were done to determine it or if they just decided to take the stock and add 25% which may be "fine" but is definitely not the ideal way to come up with rates for lowering springs if you are concerned with performance.

I know Steeda has been around forever and know more about Mustang's than i ever will but i learned a lot about suspension tuning when i had my FRS and i just would prefer to see some of the technical background on where the numbers came from.

Thanks for reaching out! If someone is mentioning the stock PP suspension seem under-damped, that's their opinion - we've been racing Mustangs for years (and still do) and various drivers have differing opinions about the same suspension setups.

Our engineering team did a comparative analysis to the OE springs and yes we've been utilizing shock dynos when testing for the past 3 decades.

With a 25% increase in spring rate over the OE springs, the factory shocks and struts are more than adequate. If you were to increase the spring rate past 50% or so, it wouldn't be a bad idea to replace the shocks and struts. We are actually working on Steeda shocks and struts as well.

Thanks David, i appreciate the information and its good to know it wasn't increased by some arbitrary number.

The reviews on the website are very good also, can't wait to see what else you guys have coming for the EB cars.
