This is a thread we need. However I don't think I'd put any of those coilovers up on there, except for the RS-R ones. Anything that says it works for previous gen and current gen Mazda 3s is sketchy. The suspensions are different and shouldn't work the same
I'll just mark them as unconfirmed for the time being. That way when we have users that have tried them out we can update the thread. The BC racing BR coilovers were listed the same as these others at one point. Then CarbonSmoke got a set and proved they work.

That works. Carbon smoke got his specially made. These listed from ebay are for the hybrid version, which I remember needed some sort of special adapter or nut or something

@known2ridenaked, Amazing job!!!
When I asked for a list of springs/coilovers I never expected someone to put together something done as well as you have, especially in such a short amount of time.
:D
Thank you very much!!!

Nice compilation. I've made it a sticky and will be adding it to my welcome letter.
My Body Kit thread didn't get stickied!!! :(
Lol.

I looked a little deeper into it and made the proper corrections. The link now directs the user to a set of N-03's and a note has been added that they need to contact their dealer for additional parts. Sorry about the mis-post and thanks for catching it for me.

(EDIT: Please disregard Topic 1 due to what I discovered and listed in Topic 5)
Topic 1: Visual estimation of the AutoExe difference in ride height from stock...
Okay, I'm listing this in order to see if you guys are seeing the same thing as me.
In terms of drop (from least to greatest) with lowering springs, the order seems to be:
Stock/OEM: 0.0"(F) / 0.0"(R)
Eibach: 1.0"(F) / 1.3"(R)
RS-R: 1.2 - 1.4"(F) / 1.2 - 1.4"(R)
AutoExe: ? ? ?(F) / ? ? ? (R)
Corksport: 1.75"(F) / 2.0"(R)
Would you all agree with where AutoExe is placed?
It's kind've hard to compare the image above for AutoExe with the Eibach pics since the Eibach pics are so small.

Topic 2: Providing more pics of the RS-R springs and details on those pictures
Also, @known2ridenaked, for the RS-R springs, it might be better to use the image from this post, which has the side view of @dennisheffner's car.
Alternatively, I've added a picture that simply has both of his pictures side-by-side which might be better to have for the OP. I just thought it might be better with this picture since all the other ones have side views of the car so it would be helpful for comparison.
Either way, the image has now made it to the thread, even if it doesn't get included in the OP.
Also, HERE is a link for the RS-R Spring Kit since there isn't currently a link to them in the OP

Also, since @dennisheffner doesn't have stock wheels, I'd figure I'd list details about it in this thread so people did not need to search through the other two threads:
Tire Size Specs: +42, Factory size stretched. Wheels are 18" x 8.5".
Settled ride height was 1.2" after 200 miles in comparison to the estimated 1.2"-1.4".
I'm not sure what half of these numbers mean, but hopefully it is meaningful to others.

Topic 3: Mazda UK happens to have OEM lowering springs, but they give very very few details about them (they give none actually). Here is the link to them:
Mazda3 Accessories
While the link has "2013" in the title, the lowering spring kit is actually linked through the accessories for the 2014 model. Perhaps Mazda UK goofed up, but they are listed. I believe someone mentioned that they were a 20mm (0.787 inches) drop some where in the forums.
Price in U.S.Dollars = $277.10
Here's the topic I started about the Mazda UK Accessories in case anyone wants to check whats in it: http://mazda3revolution.com/forums/2014-mazda-3-skyactiv-discussion/55386-mazda-uk-accessories.html
About the only thing to take from the thread (in terms of the springs) is that there is a kit for gasoline engines and a kit for diesel engines.

Topic 4: Corksport Installation Instructions
Can be found at the link listed in the OP, but here is a link that will take you directly to the PDF.
The instructions seem pretty thorough, and I assume that these instructions would work for any of the spring kits above, not just the Corksport ones. Assuming that's the case, I wanted everyone to be sure that they knew about it.

Topic 5: I'm simply going through all my bookmarks to make sure you managed to include everything, I mean... it's no fun to leave any details unspoken, right?
Anyways, based on THIS link, it would seem as though the image you included for the AutoExe springs is actually an image for the RS-R Ti-2000 springs.
I'm not sure if these are the same RS-R springs that we have listed above or if they are different.

AutoEXE does still seem to be offering their own set of springs though.
While AutoEXE does not have details for their springs on their own website, I have found them being sold here:
????.?????:a5a8a5f3a55:HYOGOPARTS - T?????????????????? - Yahoo!??????
There are 4 spring kits, I have no idea what the differences are between the kits, but they all have a picture that says 20-40mm.
There also seems to be a set of coilovers on the page as well. It has an image towards the bottom that lists specs for the BM.
I'm not sure if any of those options can be trusted since I don't speak Japanese and therefore don't know what they say, but I felt like it should be mentioned.

Topic 6: In addition to dennisheffner's pictures, I'm also attaching some other pictures of 2014 Mazda3s I've come across on the internet and the forums that have not already been shown in the OP.

EDIT: Found a spec sheet for AutoExe parts, image is now attached.

EDIT 2: I remembered ATH also listed some springs on their website. They appear to be H&R springs
Option 1 (Gasoline) || Option 2 (Diesel)

@WandererTJ
I've made some updates to the OP from the list you provided. Thanks for pitching in. I knew when I first created it that I would miss some things. I really appreciate you going over it with a fine tooth comb and picking out the deficiencies for me.
@Oshiguru
Thanks for the part #. I've added it as a note to the BC coilover portion and when retailers start offering the part number I will change it again.

Right. So they should just be removed altogether
The RS-R's haven't been confirmed by anyone. Once someone tries them out they will be moved out of the unconfirmed area. The BC Racing BR's (hybrid) was a mis-post on my part and has been updated and corrected. At this point they are the only ones who are making coilovers for our cars that someone has installed (at least on this forum). There is no way I'm going to remove them.

Yeah I was just talking about removing the BC racing hybrid coils. Since those definitely don't fit and the BC coils that are built for our cars are only about a month away. So there's no need to keep those ebay hybrid ones up there

After seeing a nearly identical 3 to mine this week, I've decided that I can't wait on an airbag kit to be ready.
As such, I will be ordering the Eibach springs. While I like that the RS-Rs ride a little bit lower, Eibach's website just looks more professional, plus they give additional details on the alignment and such.

Once they get in, I'm going to need to find myself an installer I can trust. Maybe one of the mechanics I go to for japanese cars will be able to install them.
