Help me understand

So I'm deciding on either the H&R Springs or go out with the BC Coilovers for my 15 Mz3 (~19k miles), but obviously the biggest concern is cost and what I'm really using them for.

I read somewhere that you should really only need coilovers if you are hitting the track, and springs are just fine for a DD. I don't ever plan on driving track or racing, but I rather go for something permanent, and long lasting.

I leaning towards the coils, but considering springs definitely because of the cost. However I see the people who go for springs usually end up also getting new struts/shocks, and in the end paying roughly the same as coilovers minus $100-300 anyway, so I'm confused on what's the point? Is it because they can get the springs now and save for the struts later?

If you want adjustability and height, then you want coilovers. If you are set on a height and find Springs for said height then all good. Just depends on what you want.

What you should be concerned about is how a new suspension will effect how the car rides. For a daily driver, coilovers might not be a good thing. Spring rates can be a problem. A lowered car needs stiffer springs, and stiffer springs need shocks to match or ride will suffer to varying degrees. Most cheap Chinese coilovers like BC are geared more for the stance crowd, less for the daily driver unless you like bouncing around a lot. Low is not necessarily good either as you will be scraping curbs and bottoming out in every parking lot. The H&Rs are just about as low as you want to go with your car and keep it practical.
As far as cost goes, you can get a set of H&Rs for about 250 and a set of Koni FSDs for just under 600 vs 800 - 1000 for a low end coilover setup that you might regret installing. You can get better quality coilovers but then you start getting closer to 2 grand.
If you are going to replace the suspension, its better to do it all at once and get it over with. You have to take it apart to change the springs or swap the shocks, no sense in doing it twice.

My question is what H&R lowering springs work for a 2016 mazda 3 sedan?. Im looking in their website but they don't seem to have it for said model.

The info you need is in other threads that talk about the H&R springs. You just need to look around a little bit.......

If you have a limited budget, you can always go with the springs alone & then add shocks at a later time, when you have more cash. You'll have to pay for installation twice, but you can split the cost up, which may make it more manageable in your budget.

I'd definitely recommend springs & Koni FSD's over coilovers for a daily driver. You'll have a much better ride!

There are many links and references to these springs. Use the search function. There is also a springs and coilovers sticky at the top of the suspension subforum in which H&R springs are discussed.

H&R part 28821-1

H&R lowering springs for 28821-1 Mazda 3 fits Mazda 3 VA 30 HA 45mm | eBay

From here on if you have a question please make a new thread. Don't attach it to another thread.
