This is where it gets tricky, people sometimes buy more than what they need for street use or very limited track use.
You mentioned the Steeda adjustable sway bars, that whole Steeda sway bar package is almost 1K. So the question becomes on the street are you ever going to come close of getting the benefit and or full potential of a 1K sway bar package even if it is adjusted to the lowest setting for the street. What I'm getting at here is like I mentioned my PP sway bar up front is around 32mm rear sway bar around 25mm and these are factory sway bars.Thats is a really good sway bar set for the street and would do dam good on the track as well. Also you start putting huge sway bars on a street car you start going into the harsh ride spectrum. Also using the steeda sway bars with factory springs depending on the spring rates you could start to have other issues, you might not notice it on the street but pushing the car hard on the track theirs a good chance the suspension components would not work cohesively I guess is good way to put it.
So you could save yourself a whole lot of money by checking ebey or call some used car part bone yards and see if you can get a set of PP sway bars.
The reason I bought all the control arms was like I said mostly for the bushing up grades to get the deflection/squishy feeling out of the suspension if their was a bushing kit for the factory camber arm and vertical link I would have went that route, their is no bushing kits.(I couldn't find any) After getting the squishy feeling out of the suspension, that allowed me to start focusing in on the struts/shocks and springs. At that point I felt the springs weren't that bad for how I wanted my car set up. Turning my attention to the struts/shocks I knew they were junk, the big tip off is obviously how they don't simply perform but the fact that Ford offers shock/struct up grades with handling packages. Sadly even with the PP package on my 2019 it still sucks, its just a bastardized package that looks to me like Ford picked through existing parts bins to offer something. The best upgrade is the brakes as too you can say its actually beneficial to the cause and the sway bars.
The reason I went with the Steeda non-adjustable pro-action was on Steeda's web page they have a chart that shows Steeda's recommendations. Since I was using my factory springs that was the recommendation according to the chart.
Yes Steeda is correct in their recommendation it says good for the street and good for the track as well. In my opinion
the way these struts/shocks are valved/tuned is what strut/shock should be on the eco boost PP FROM THE FACTORY.
I would gladly forego the dash gages, rear spoiler, aluminum spun dash and hell even the shock tower brace for a good set of struts/shocks.These struts/shocks really settle and control the suspension even over a very bumpy road the tires stay well planted, I never felt the bumps were getting ahead of the struts/shocks. They are more firm and you feel the bumps more, but its controlled and not jarring. Again on my PP it says it has heavy duty springs on the front, what that exactly means from Ford I don't know but it wouldn't surprise me if they were GT springs. I don't know what the spring rates are front or back or how much they differ from a base eco boost.
So the way I wanted my car set up was defiantly more for the street than the track. the drawback is like I said you have to buy complete suspension arms to get the benefit of the bushings which is the only way your going to get a tight suspension. I know there are people who put lowering springs on their car and start raving about the handling, well yes it is true the car is handling better, but its really masking a soft crappy suspension as far as the control arms are concerned and they can only mask the weak suspension arms to a point.
My suggestion is start with the rear cradle alignment kit and rear cradle support kit. these two things will get your rear cradle aligned with the rest of the car properly and get some of the squishy flex out of rear suspension, plus they are not that expensive. You can get the Ford spherical bearing rear toe arm fairly inexpensive upgrade. The rear camber arm upgrade isn't a must do unless you go with lowering springs, but the rear vertical link is, your choice delrin bushing or poly bushing poly bushings are cheaper. Struts/shocks a must do factory base struts/shocks are horrible. Talked about sway bars already. If your looking to do a fun street car with once in a great while track day and you don't want a stage coach stiff ride on the street this is what I found taking apart and redoing my suspension all the work I did myself so any more questions feel free to ask.
