Default Ok, this might b a stupid question about lowering

If one were to get 20" wheels and put tires that would make the diameter larger than stock (ie. An inch or so,) wouldn't lowering it an inch equal the same ride height as stock?

Or is that possible?

that doesnt sound correct... if you lower and go to bigger wheels it would be more than stock...

Technically, pretty sure you're right. If the overall diameter is one inch larger than stock, then you're right height will be an inch taller.

Yes you'd increase ride height, but say goodbye to accurate speed readings.

If you put tires that have an outside diameter 1" bigger than stock and lowered by 1" your ride height would be 1/2" lower. It would be the same with a tire that is 2" larger in diameter (1" larger radius)

If you put on a 1" larger diameter tire it would mess up your speedo and likely create a lot of rubbing issues, not to mention it would probably look huge. That is regardless of rim size.

It's all starting to make sense now. After looking at all the dropped cars on twenties, I thought the ride height looked the same as stock on a few.

If this is the case, I can go with 20s and have the same ride height as stock and be okay in the winter

So, all the lowered 3is on here with twenties have lower ride height than stock?

It doesn't matter what size the rim is, the overall diameter doesn't change. As you go up in rim size you reduce the sidewall thickness, not the outer diameter.

A car lowered by 1" will be 1" lower than stock with any sized rim with the correct tire on it.

"Correct tire on it" is what I am referring to. A lot of guys put lower profile tires on them.

I understand the wheel size doesn't change anything. My goal is simple. Run twenties without a big gap between the tire and wheel well, and have the same ride height for snow. Or at least within a half inch or so.

By the sounds of it, this is possible with RS-R downs that go 1"

If one were to put the correct sized tire on, the overall diameter should not change (relative to the stock diameter). Sure you can put an "incorrect" sized tire on to counter the lowering of the suspension, but you will run into issues that were mentioned above. Therefore, keeping the car at stock height with lowering suspension and running on correct-sized tires is not possible. If you can tolerate half an inch of change, then get coilovers since there are currently no springs that will give you the desired height. Someone correct me if I'm wrong. Thanks!

Guess I'm screwed for twenties.

Personally, with a right-styled wheel, a 19" could look as large as another 20" wheel. The Niche Targas you're considering are a good example since the spokes reach to the edge of the rim.
