I'm a little confused by your reply. My reply is simply to the OP. Where I live, we have a substantially higher amount of tight curves than a large part of the US (Appalachian mountains/ NW SC, SW NC, SE TN). We do have straight interstate highways as well. With that said, road maintenance can become a bear sometimes as some of our roads are pretty rough.
Sorry for the misunderstanding; I meant that in my case, due to the abundance of turns, I don’t quite understand the point of a slight lowering. I did it for better handling and to avoid any roll. But you’re right — now I have to be careful about the road surface so as not to polish the underside. Sorry again if I offended you. P. S. I installed the same Steeda, and after that, I started getting knocking noises from the rear when going over small bumps; we checked everything we could, but nothing helped. Plus, it turned out that Steeda for the S650 cannot be legally used in Germany. Yes, we need to have a special document for non‑original parts. And there are very few of them. I was riding a KW v3. And they also started making noise over time. In the end, I installed the original shock absorbers and ordered ST adjustable springs, which are approved for use with the original shock absorbers. I envy you for not having to deal with all this nonsense about approvals.

No worries and no offense taken. I actually would prefer to be lowered a bit more than I am but, unfortunately with my Mustang being a daily driver as well as something I can take cruising in the hills, I have to compromise. Between the areas, I drive in, of crappy roads (maintenance and damaged roads) and transitions (driveways, business entrances, etc.), any lower and I would be constantly scraping.
As far as the knocking noises with the minimum drop springs from Steeda, I went through that when I first installed them. This may not be the solution for any or everyone but what solved it for me was to add isolators to the springs. I basically did the installation of my suspension twice to check everything for damage and torque. Only thing I could find was paint rubbing off of certain areas of the springs. Sure enough, where the coils in those areas were touching when compressed/ going over sharp bumps caused the slight "knocking noise" and buzzing I was hearing. Steeda actually offers them on their site now (purchased separately) so I do recommend getting a pair with the springs. I ordered my isolators before they added them to the site for the S650s from a company on Amazon. I am a long time fan of Steeda so I do think that Steeda should include them with certain sets of springs, btw...hint hint.
Yeah, the state I live in and most states in the US don't require approval/ special documents for aftermarket. I am thankful for that. The one negative side to that though is some of the riff raff that you will routinely see on the roads out here. Lol, like vehicles that look like they should be deemed not road worthy/ totaled rolling down an Interstate at 80-90+ mph. I just let them get on down the road and out of my path, lol.

Unfortunately, this doesn’t work in my case. When a Steeda shock absorber and a Steeda spring are installed, there’s a knocking sound; if you install the original shock absorber, there’s no knocking. The same thing happens with KW. The knocking only occurs with a non‑original shock absorber. We tried loosening and tightening everything, checked the tightening torque — nothing helped. With Steeda, I ended up in a situation where the company promised one thing in their advertising, but the reality turned out to be different. Their website states that their shock absorbers have passed European certification. I bought the kit and installed it. But when I came to arrange the vehicle modification, they explained that the document they were using could be used for anything — it has no legal value. It got to the point where I contacted Steeda’s official partner in Germany, and they told me outright that I wouldn’t get approval for my Mustang, as the parts hadn’t passed certification. Steeda’s support pretended to be trying to help, but in the end, I ended up with a set of shock absorbers and springs that I can only use as interior items — they’re just lying in the basement, and I can’t return them. The KW suspension is noisy too; I’ve already sent the shock absorbers for repair — they returned them after the repair, but nothing changed. Then they even replaced them with new ones, but the knocking didn’t go away. I spent almost 10,000 euros on services, suspension replacements, tests, and so on, but in the end, nothing works.

Yeah, that sucks. I’d definitely volunteer to help/take a look at it if you were local. Suck also having to pay for services that don’t fix the issue. Some things are to be expected with aftermarket performance parts but broken sounds shouldn’t be one of them.
