Easy rider
so I have a 2013 on Swift springs, running 19x9 et40 square with 275/30/19 square.
In in the last year Indy streets have degraded to New York status. Our mayor has for real dropped the ball. By car makes some pretty loud thuds just on the joints in our roads, and they made the potholes worse by piling on mounds of asphalt, turning holes into moguls.
The question is, is the stock ride much smoother? I know my OEM springs will give more travel, but do they substantially increase the smoothness of the ride? I have the OEM springs but bought the car with Swift’s already installed. I thought about daily driving this car, but it wouldn’t survive a winter.
should I focus on more sidewall, or change the suspension? I am considering selling my 19s and buying 18s for more sidewall, but I may just go to stock height and throw 275/35/19s on. Thoughts?

I have a 2012, the stock ride is sooooooo smoothhhh! Then I installed swift springs, jaw breaking stiff in my opinion. I prefer the ride quality of OEM, but the car looks so good lowered. So I'm just dealing with the stiff ride.

I’m about to install USRS, so I’m guessing it’ll get worse. Considering that I have a Toms kit and Indiana blows, I may just go back to stock height and go to a 35 series tire. I actually don’t mind the ride for my sake as much as the car. It’s really taking that impact. I covet the car, I’d rather not rattle it to pieces. Do ISFs sit an inch lower than the IS350 in stock form? I have an OEM 350 so I’m trying to judge how high the stock ISF sits.
IMHO, the slightly taller sidewall with my 18" wheels and 275/35 tires makes a very noticeable improvement in ride quality vs OEM sizes. I'm lowered, and even with the recent switch to stiffer springs up front for track performance (from 16kg to 18kg), it's still very livable around town. I like it so much, I may sell my OEM wheels & replace them with another set of 18s.

I was in this situation a while back I used to commute into New York City to work from the suburbs. When I noticed I had two blown shocks. I elected to go with swift Springs and Bilstein B6 shocks. After just one week I remove the Swift Springs and put back OEM Springs back on. Though I love the handling qualities of Swift Springs due to poor road conditions I reverted back to the OEM Springs which help improve ride quality. I'm also on 255/35/19F and 275/35/19R. Did going to a 35mm size help ride quality yes it did, but not as much as I'd like. So like many others here who are now switching to 18 inch rims I too would like to go this route as well to improve the ride quality with taller side wall. I like look of beefier tire on right rim size and offset. Also if you're looking to improve ride quality and comfort tire selection is very important. Not every Tire rides the same even though they can be exactly same size. When selecting proper tire for your needs I would definitely do my research you can go to places such as Discount Tire and Tirerack where they Supply information regarding Comfort,sidewall stiffness, as well as reviews etc.

I have always loved how light RPF1s are. I may buy a set of 18x9.5 et 45 and try to run some 275/40s... but they may also rub. 275/35/18 is way undersized for our cars.... I’d hate to rack up miles faster than I’m actually driving. I haven’t really seen RPF1s on this car though, they may be a mega fail.

Update. I went back to OEM springs and boy is the ride better. I also installed the USRS while I had it apart. The steering and braking feel is amazing. Even though it sits higher I like the look because I have a lower than stock offset square wheel set-up. I’ll post pics when I get around to cleaning it.

275/35 seems to be working well for him, and no rubbing which is always a plus.
