So, it's hard to wade through 60+ pages and fine the answer I need. So I'll ask here more specifically.

What is the big difference between the two? If I went non adj, I'd most likely go either steeda w/ steeda springs or frpp with frpp springs.

What is the adv/disadv to the two?

The car is primarily a DD, might see a track pass or two during the year. I do like carving up some curves while cruising in my area. Thanks ahead of time

 

You can adjust it to your needs. Ie softer or firmer

 

I enjoy the adjustability of the koni yellows. Even if you end up not adjusting frequently you can adjust once to your liking. If you decide on the non-adj setup the Steeda kit is not a bad idea but look into the Koni STR.T as well. For the money they offer a decent performance upgrade and are less expensive to its competition.
Advantage of adj struts are shocks is in fact the adjustability, the simple disadvantage would be the cost. Advantage of non-adj is the cost while sacrificing adjustabiliy.
A kit that works for one person may not work for another, thats the risk of buying aftermarket parts. I have a few kits that have worked for me, whether on the strip or on the street. I'm just now getting into the road course (NASA) crowd so I'll be learning as I go this year.
I'm currently running Koni Yellows, Hotchkis sport springs with ground control CC plates and I love this setup. Give me a call or an email and I'll do my best to help you out.

 

As mentioned, adjustables will let you tweak them to suit you and your specific driving, which will not necessarily have you set identical front and rear adjustments.

You can adjust them to suit other changes in the car, such as different springs or different bars or even different bar adjustments.

You can dial the stiffness up to compensate for age & wear, or for autocross or a HPDE at a road course such as VIR. You can also soften them to suit passengers who are less tolerant of a firm ride than you might be.

I can tell you that Koni Sports work just fine with the OE springs.

I am set to pick up my mustang in a couple of months and had questions about the suspension as well. I have heard many people talk about Koni yellows, and other kits that can be installed. I have not heard many people talk about the Roush suspension kit. Below is the link of the item I was looking at, and I wondered how it would compare to the other options that have already been discussed?

 

Forgot the link.

It's kind of hard to compare it against anything when Roush doesn't provide any numbers to compare or insight into who actually makes the various components.

That's not a put down for the kit, just saying that there isn't enough information to base a very complete opinion on. The claims of better ride quality and lower NVH than most other kits are believable; however no mention is made concerning, say, resistance to wheel hop.

I might even be interested in their 1" springs, except that no rate information is provided and because the product description makes it sound like Roush doesn't want to sell the springs unless you're going to be using more of their kit pieces.

You make a good point.

 

Another advantage to the yellows is their versatility. Yes, you can initially adjust them to suit your preference for handling vs. ride in a daily driver situation. But also, if you start feeling froggy and you want to take it to a drag strip, you can soften the struts, or if you feel like attending an HPDE, you can stiffen the shocks and struts. So the adjustable dampeners are more versatile than a one size fits all option.
