I am on Tanabe Coilovers and I feel every bump and some hurts bad. I think the ride was much more comfortable with the oem suspension on.

 

You already think the fits suspension is bad? I wouldn't recommend changing out suspension. Oem suspension will be the most "comfortable " set up. Idk if you've modified cars before, but the cost of changing out suspension and tires will greatly vary depending on what you get. Also, will you be cutting out the cost of labor by doing the work yourself? What you should really ask yourself is, how much are you willing to spend for what you want.

With your post, it seems like you want more comfort than a sporty ride. From what I have experienced, companies either aim for oem spec ride quality or stiffer for a sportier ride. I'm not sure if you will find the suspension you want, but tires you will.

 

 

I dont have any first hand experience into suspension/wheels and this response only adds to the above responses, while ignoring the OPs new ask for cost.

Edit: i payed $42/tire+$10mount/balance (with 40k mile warrenty and a $10 flat fix/replacement guarantee) for walmart generic tires recently for the lols. The ride is about the same. However the Continentals that i had previously were a much better ride on the highway, and less sloppy feeling in hard cornering.

i have done a fair bit of research into this, and 30k+ miles on the oem setup. So here's my 2 cents:
oem suspension and tire thickness is perfect for everything from cruising to smashing through gears around twisty roads.

the down side to the oem suspension and wheels is the aesthetic, supposed handling in hardcore track scenarios where coilovers may be desired, and perhaps mpg on the highway may increase slightly with a moderate bit of lowering via a proper set of springs that match the rates of the oem shocks.

coilovers and lowprofile tires as a daily application in areas with mediocre or poorly maintained roads is going to put a lot of cringe worthy smashing stress on everything in the car.

 

I haven't modified the stock suspension but I did put on a set of Pirellis a few weeks ago and do notice a difference on feel and performance. I upsized to 205-50/16 (OEM for my EX is 185-55). It really feels less harsh overall and seems to a bit gentler on those jarring bumps and way better cornering. First time on the interstate was a dream, but second time with a strong crosswind it did feel less stable and more floaty. It's still early days so I'm not ready for a thorough review but so far it's two thumbs up.

 

15" wheels & tires would be more comfortable as a result of a larger sidewall to absorb impact.

That's your only real option IMO.

 

 

Your current wheels are 16".

They have 185/55/16 tires.

With 15" wheels (you'd need new wheels), you could run something like a 185/60/15 for a bit more cushion.

You'd need new tires & wheels.

Realistically don't change anything because it is more likely than not if you don't know what you're doing, you'll just spend money without any gain.

 

 

I recently went the opposite direction you're considering - switching from 15" steelies on my '16 LX to 16" alloys from a GE8. 185/60/15 to 185/55/16. No difference in speedo readout, thankfully.

Do I notice a difference? Of course. The larger wheel has a lower profile tire, so it doesn't absorb impacts and flex as much as the smaller wheel would, like mike410b said. On the positive side, I actually like the ride with the 16" wheels better. Seems more composed over rough surfaces, and we have plenty here. The fact that I was upgrading from the lousy stock Firestone tires to Sumitomo's didn't hurt either.

I could live with either one, but I prefer the 16's. Maybe checking out different tires the next time you need them is the best / least expensive option.

 

How is your tire pressure?
There have been a couple times in the past when I got brand new cars delivered with 40+ psi all around.

I'm on stock suspension, 7" wheels w/ET40 offset and 205/50/R16 Kumho Ecsta PA31s, 33psi front, 35psi rear (+3 from recommended factory number)
The car feels just right, the track is effectively 2 inches wider and while not nearly as mushy as on the skinny-soft OEM Firestones, it is far from harsh.

 

I also recommend checking your pressures if you haven't already. Tire pressure can have a profound affect on ride quality.

I have a 2018 Sport and I'm always impressed with the factory ride quality when my pressures are dialed in to the factory recommendations.

 

I can attest to that.
I have my rears at 35psi and while it helps reducing understeer, the ride is significantly more bumpy at the back.

 

Look for a nice gel or memory foam cushion to sit on. It's cheap and will provide you with more comfort than anything else you can spend your money on.

 

This highlights the point that there is a range of tire pressures that can be actually used. Honda's recommendation is their opinion of what provides the best balance of ride and handling. But you can deviate from those recommendations to gain something else...like reduced oversteer. Just be sure you don't deviate to the point of making the car unsafe and understand there may be unwanted consequences like bad ride quality or abnormal tire wear.
