The 2015-2017 cars are worse than the 2018+ cars in this respect. Thats why going with lowering springs with more rate and keeping the stock dampers are a recipe for ill handling.
More specifically, if you lower a 2015-2017, it’s advisable to have the PP shocks and struts at minimum. Otherwise, you’ll end up with a bouncy jittery nervous feeling on bumpy roads, and it’s not fun. Tolerable under normal driving, but any upset to the wheels sends the stock shocks into a tizzy.

Even with the 2018+ parts, not just as bad.

Just FYSA — I’m now running FRPP Street X Springs, Bilsteins, and Steeda’s adjustable bars. The ride is sublime and handling is on-point. Heaps better than a PP’s suspension, and much more compliant and enjoyable on New York’s pimpled roads than with my prior stiffer springs.

For those reading through this thread, really consider a damper other than the Street package’s OEM PPs, and grab better sway bars than this package offers if you’re going through the trouble of installation. The X-springs are excellent; only good words.

I've got the street handling pack along with the other stuff in my sig.

I have zero complaints about it. For a car that only sees street duty it's so much better than the base and a perfect mix of comfort and handling. The overall ride height ends up great as well.

The roads in my area are terrible but the car feels great on them.

But to each their own. Some will say it's shit but I really have to disagree and couldn't be happier.

Ride height ends up like this....

Does anyone have this kit on a V6? If so, thoughts? I want mine to be a bit lower but handle better on the street. I’m not tracking the car, but I enjoy a spirited drive to work or when I’m out.

Here's another pic when the car had different wheels. I plan on getting rid of these and going steeda progressive.

Would like to see the difference and get your perspective on the Steeda Progressive after you’ve changed. I had the adjustments discussed earlier in the thread and the rear still looks the same.

Unfortunately it won’t be any time sooner the steeda springs. I did meet up with a bunch of other s550s on a rally and I noticed my rear being higher then most. I was behind a steeda progressive spring car and visually I could tell it sat lower than our X springs cars. Either one are great just depends what look your prefer.

Here’s a few photos of the X springs on my car. This is 3 weeks after install — the rear of the car was laughable high for about a week, but has settled nicely:

The fenderwell gap from front to rear is nearly identical at 1.15” (front is 2mm less gap) with my staggered setup. I run 275/30/20 and 305/30/20 MPS4S. Very pleased overall — the ride is super good.

Yeah, I really like the ride on the X springs. I can barely fit 1 finger between front wheel and fender and I can fit two between rear wheel and fender. The front dropped almost 1.5” for me. I’m having my dealership look at tomorrow while it is in for other work.

Considering your large diamter tires, the front seems to be in line and correct — the rear with your 305/35/20s is about 0.5” too high. Let us know how it goes.

Rear did drop a little after the dealer made adjustments with full weight of car on the ground. Still not as far as I had hoped, but hoping it might settle a bit more in the next few weeks.
