Hey man! thanks a lot for this post, I pre-ordered my super down springs for my 2014 IS and I was unsure if I had made the smart decision, but after seeing your pics I defiantly made the right one! I wanted to no wheel gap how you have it.. just sucks I gotta wait until mid-December to put them on my car but definitely will start posting pics on here of it!

The wheel and tire specs on my car are:

19x9.5 +32, 265/30
Here is the car dropped on the RS*R Super Down springs
And here is the car on the RS*R Down springs
As you can see, the Super Down springs pretty much get rid of the entire wheel gap, and look AWESOME!!!
Unfortunately, due to the aggressive setup I have in the rear, and the way the fender curves inward, I couldn't drive the vehicle with that setup. The sidewalls of my rear tires would be chewed up in no time, as well as the wheel well. I could have tried some extensive fender & rear bumper rolling, but still may have rubbed over dips and bumps.
With the Down springs, there is still some minor gap:
However, any lower and I'd probably start scraping on my own driveway, especially when I have a front lip installed:
As for ride quality- the car rides great! It feels slightly stiffer than the OEM suspension, but not so stiff that the ride becomes uncomfortable. In addition, it feels much better handling around corners and turns-- not so floaty as the OEM feel.
I can't perform what I hear is known as the "Girlfriend test" but I'm sure that if I could, the car with this suspension would pass with flying colors!
There are also no rubbing issues with front or rear wheels on this setup, and I've tested it at 120 km/h, or about 75 mph, on the 5 freeway out here in So Cal (Which, for those of you who are local know, is uneven and bumpy as hell!), and there was no rubbing going over the uneven portions of the freeway at that speed.
As for Speed bumps, I've also tested this out in a parking lot and in order for the rear wheels to rub, I need to go about 15-17 km/h, or approx 10 mph, over a good sized speed bump for the rears to rub. Now, of course, I won't go that fast over one ever again, and once there is a lip on the car, I definitely won't be going that fast haha. But I was just trying to find the threshold for rubbing.
Overall, I'm VERY happy with the outcome. I do love the slammed look, but I also like the setup of the rear wheels, so...well, I can't have my cake and eat it too
the rear drop of your car looks lower than the rear drop on IntegresS.. u both run 19's... And same springs.!! I received my rs-r down springs today and I'm little unsure how the car will sit. Eveyones drop looks different. I'm going vossen 20's but it's driving me crazy with all the different heights iam seeing lol . Rant over lol
