I have a Mazda3 2011 HB 2.5L mileage around 118k.
My front struts have signs of oil leak. There's no rattling or noise, but I want to change them before it gets worse.
I need suggestions as what are the best options (brand, model, where to buy).
I use the car for regular driving, nothing fancy or spirited.
If with not much $ difference from the regular ones I can get something better than OEM, I'd be interested.

Do I need to change to coilovers as well (just curious)? or they don't need to be changed?

Thanks

sorry for late reply, you only need to replace the strut, you can keep the stock spring assuming you are staying stock height, and not lowering.. The strut is the thing that is leaking, but you may or may not want new tophats or strut mount too, I replaced my struts and springs with koni yellows and lowering springs but my tophats (strut mount assembly) seems to be giving out now, maybe cannot handle the new spring rate or just getting old and making noise.
I recommend the brands kyb, or monroe for OEM like performance.

If strut mounts or struts goes bad, it wont be a loud sound, maybe some minor clunking sounds going over some bumps.
but if you hear louder or lots of clunking sounds its possible it can be endlinks also going bad.
I just replaced both strut mounts + the front endlinks and no more clunking sounds are coming from the front end. (note I already upgraded my struts and springs to koni yellows with lowering springs.)

And yeah the clunking was never there until after I lowered my car (old oem junk endlinks and strut mounts might not handle the new sportier struts and higher spring rate from the lowering springs)

Any particular reasoning for getting KYB or Monroe if they are the same as OEM? Are they cheaper? Or better stability?

Asking as I’m looking to replace my OEM shocks as they are reaching their end of life.

Thanks

KYB makes Mazda struts, why pay dealer prices when the GR2's are pretty much a stock replacement?

Koni Special Active are really good. I just installed the front struts and am loving them. Much better than stock and pretty reasonably priced.

I'm going to do the rear dampers tomorrow too.

Proof or conjecture? Ive been happy with any car ive put them on.
They are better than blown out OEM dampers and not a lot better than new OEM dampers.... There are much better options available. KYBs are for the ricer crowd who want pretty on the cheap and don't really care about actual performance.

Thanks. I’ll have a look and see how the pricing compares

What options would you recommend for me other than KYB and OEM? My Mazda 3 is a daily driver with a young baby. I would like a comfortable ride but with a more stability around corners. Thanks.

If you want better dampers, the Konis are pretty much the go to parts it seems. Bilsteins are ok but may be a little stiff.

With the Koni, would you go STR.T (orange) or sport (yellow)?

My basic understanding is that the sports have adjustable dampening while the STR.T doesn’t. Any other significant differences?

If you can find them, the red Special Actives or the gold FSDs are the way to go. What year is the car?

2012. I’m assuming that the red special actives and gold FSDs are quite pricey. Don’t really want to drop much on this car as I’m not looking for performance.

Yes, about $500. If you want something better than OEM, its going to cost more than OEM. Thats just how it is, you get what you pay for.

Just installed the Koni Special Actives.. they work amazing on my lowered ride that has a pretty aggressive negative camber. For a stock DD you will be super happy with them. I got mine from tirerack. Arrived in 2 days in perfect condition and they were on sale..
