Is the ride quality on 18s noticably better compared to the OEM 20s?

Wheels I was looking at:

You can most likely get these at a better deal from @System Motorsports if they have them in stock. They're a vendor on here.

Sweet, good looking around. I was just on that site looking at shift knobs primarily. Titan 7s also piqued my interest too.

Night and day. A good, lightweight set of 18s with sticky tires, is one of the best upgrades you can make to the Type-R!

Why are people always recommending 18's over 19's? Is it just because of more protection for the rim? I would choose 19's over 18's because I like the thin tire look but that's just me.

Tire price and amount of side wall are probably the biggest reasons. There seems to be a substantial difference going from 18-19. 19's seem pretty close to 20's in regular price.

I have those exact wheels with Firehawk Indy 500s at 265/35/18. No lowering springs. Here’s what I’ve noticed, some of it might have to do with the tires though:
1- Yes, you’ll feel that it’s less direct. The difference is noticeable but I wouldn’t call it soft. That change when you switch from Sport to R mode is less shocking.
2- That annoying wheel hop when accelerating hard is diminished some. Feels more like a burnout less like wheel hop.
3- Regarding curves, it feels like I lost some traction (lateral acceleration) with the 18s. Still, it’s a more progressive/predictive situation. Frankly I prefer it this way.
4- Speed bumps and pot holes are no longer painful/scary. I’m also not freaking out about curbs either. Big quality of life change.

It's a night and day difference to me, especially if you're lowered.
When lowered, I felt like the OEM wheels would rattle your teeth out.
Then when I put the 18s on, it made the car feel like it did before lowering it.

Tires play a big role in ride quality as well. Make sure you get a good set of tires.

What are some recommended tire sizes on 18s? Preferably the more sidewall the better.

The usual 255/40/18 or 265/35/18. If you’re planning on lowering in the future, go with 265/35/18.

I just switched last week to 18 inch wheels with a 255/40/18 tire. I feel like I lost more direct feel than I thought I would. The car is smooth and it seems easier to drive fast without worrying about potholes. To me its a much more comfortable, softer ride but the car did seem to lose a little of its edge at least with my set up.

Everything listed here is from tires pretty much.

1. Less direct is because of tires. Feeling from Sport to R being similar (assuming you mean when turning) is due to wheel weight.
2. Less grip = more spinning in this case.
3. Less grip again.
4. More side wall.

I’m running 265/35-18 Michelin Pilot AS3 and there is definitely a difference in ride quality.

You think none of these changes would’ve happened had I gone with PS4S for example? I guess what I’m trying to say is, the point of going from 20 to 18 is to add some sidewall. Extra sidewall will be responsible for all of these regardless of which type of tire.
