Hey Guys,

I was just curious has any one installed this EOS rear diffuser?

https://extremeonlinestore.com/colle...46628177445034

I really like the aggressive styling. I also have the Morimoto tail lights so losing the reverse lights is not a concern. Just curious about how the fitment was?

have found many install videos of their OEM style carbon rear diffuser, seems fitment is spot on, but none of this one. I have seen people get different brand diffusers similar to this design and fitment was awful, which is making me a bit hesitant. I do have a few of this companies other products and so far fitment has been great.

 

That does look nice. Wish they made it in gloss black. Another option is C7 Carbon but just checked their site & their prices have skyrocketed.

 

This looks to be a new diffuser by them. Can't find anyone who has this installed or even purchased yet. I'm curious as well.

 

If the fitment is like their other parts, I can’t see why they wouldn’t be good to go.
Isnt C7 carbon basically the same nurturer in China just with a silly markup ?

 

That would be interesting to find out. So many vendors out there with horrible customer service too.

 

I can confirm that c7 Carbon is worlds above EOS on quality (can't confirm where its made but I was under the impression its made here in the US). That being said EOS makes some pretty nice stuff these days for the price. Been eying this diffuser as well.

 

I went ahead and pre-ordered it so I guess sometime next month I will let you guys know how the fitment is!

My experience with EOS customer service has been great historically. My hope is if it the fitment is not good I can just exchange it for their OEM looking one, which I know fitment to be great on.

The only thing with this diffuser I am confused about is I really wonder how you bolt in the tabs that sit between the exhaust tips? Unless the photo's are misleading and that "under tray" does not extend fully out I don't know how you would get to them? I guess maybe from behind that tray reaching in? Unless it is not as tight against the exhaust tips as it makes it appear in the images.

I am going to give them a call today and see if they maybe have a PDF instruction guide they could send me over on that part.

 

Please keep us updated! Take some install pics and let us know how it goes.

 

I had some C7 Carbon parts on my GS & they were great. Their gloss black race diffuser is $1,250 & I remember when it used to be ~$700. These "aero" parts prices way out of hand. It's the same with my new M2 unfortunately, splitters for $1700-2200+, side skirts the same. Get out of here.

 

I'm pretty sure my spoiler is C7 Carbon though I have no way to confirm (bought it used). Super happy with the quality though. I will say the actual aero stuff seems wildly overpriced but like you said, seems to be the theme these days. If I wanted the look and performance though they for sure have the nicest looking aero out there. Function over form though, 9 Lives Racing all day long lol.

 

Absolutely! Fingers crossed fitment is great, I really love how this thing looks. I have the stock NPP axel back and I am hoping the design of this diffuser, surrounding the exhaust tips, helps eliminate my not liking how small the tips are haha.

 

Updated info.

Called EOS today and it turns out this is a brand new product. There is indeed no information online for fitment or install.

They told me to email their technical support for my fitment related questions. Pending the answers, if it requires any modification, I may alter my order to the OEM style diffuser. Will keep you guys posted.

 

Like it but wish it had other options like flat or gloss black

 

I agree, I’d buy a flat black one to match the rest of my ground effects.

 

Hey Guys just wanted to keep you all in the loop.

I reached out to the EOS customer service number. Unfortunately, they did not have any answers to the questions I had pertaining to fitment / installation. They advised me to reach their technical support email. I went ahead and did that and they were also unable to answer any questions I had. I also was curious if the 5-6 week lead time was accurate, they informed me that it was not. They told me they really do not know when it will be in stock but probably 7-8 weeks. Then probably a few more weeks to ship out to customers. Between the long and unclear wait time as well as lack of installation information I decided to cancel the order. I still really like this design so perhaps over the summer when there is more information I will go ahead and order it. I am just imagining myself waiting 2-3 months getting it and it requiring a bunch of modification and me losing my mind haha!

All that said I went ahead and ordered the carbon fiber oem style one from another vendor who had it in stock. Should be here next week will let ya'll know how that install goes.

 

I'm leaning towards getting the ARP diffuser. I've read a few threads about fitment and installation being a bit rough, but I'm guessing most of these need a little persuading to fit properly.

 

Yeah I have seen some hit or miss reviews on the install / fitment. From what I have seen the OEM style one's seem to go on fairly smooth. Pending on the vendor it seems the L brackets on the diffuser can require some modification. We'll see my diffuser should be here sometime early April so I should have a good idea on fitment by then.

I will wait and see what others have to say on EOS new style diffuser maybe I will get it down the road if I do not hear m any horror stories.

 

Hey guys just an update. I ended up ordering a OEM style diffuser of EBAY absolutely HORRIBLE fitment do not order off there. Thankfully got a full refund.

I ordered the EOS OEM style diffuser came in and the fitment was absolutely immaculate. Really cannot speak more highly on their products they are a "reasonable" price compared to competitors. The fitment has been great ( I run their ZR1 style lip, skirts and spoiler) no different with the diffuser. Only thing I will say is if you are running the stock NPP exhaust, like I am, getting to 10 mm bolts is a pain in the butt! The passenger side one is not to bad you can get a long extension on it. The driver side on the other hand I had to remove the one hanger kind of pull down on the exhaust and get a ratcheting wrench in there no easy task. Other then that the install was not bad between removing the old one and installing the new one it took about 2 hours.

I also spoke to them on their new more aggressive style diffuser they expect it to be av available sometime early June. Based on my experience with the OEM style, which has way more room to work then new style, I would not recommend that new style if you have NPP exhausts. I have no idea how you would get to those 10 mm bolts with the exhaust enclosing.
