BMW M4 Carbon Fiber V-Style Rear diffuser for $320? Install and Review. (Fit's M3 too)

M4/M3 Carbon Fiber V-Style Rear Diffuser: bit.ly/M4V-Diffuser
I picked up a real carbon fiber v-style rear diffuser for my M4 on Aliexpress for $320 shipped! In this video, I review this diffuser and show you how to install it. This piece comes from a professional Chinese manufacturer and is the same V-style replica diffuser you see most lesser-known performance shops selling and even the well-known vendors. I also talk about why buying directly from China isn’t a scary option and bank account friendly.

Was debating, but after this video i feel a little more confident on getting it! Thanks man!!!!

[@novagarage38]

NP tony. I know a lot of people feel are apprehensive about ordering from China/Aliexpress, but that where most companies are buying it from anyway, might as well cut out the middle man. Thanks for watching!

[@fengcoretec9]

Just the kind of diffuser I was looking for at a reasonable price. Amazing detailed instructions too. Will give you a shout if I decide to make the purchase. Thanks!

Nova man, i hate you. I hate you for making me spend so much on carbon bits from their shop BUT i love you at the same time cause it all turned out great. From a front lip, side mirrors side skirts and a diffuser - my car transformed on a budget. Thanks again for making this vid man :)

Nice job, very helpful. Thx!

[@novagarage38]

[@tsamonte]

@@novagarage38 Just curious. Who recommended the seller to you? Sadly i learned the hard way and bought a spoiler from a less reputable seller on aliexpress. I received a totally different spoiler. As you can imagine i'm pissed and feel so stupid for falling for it. Now i'm stuck with a useless spoiler and have 2 options. Return spoiler and get full refund ( who knows if they will actually receive it and I'd have to pay for shipping costs) or 2. I keep it and get half my money back. I rarely get scammed, but they got me this time! Would you totally vouch for HSPEED KSLINE? I'm so hesitant now from ordering through aliexpress. Thanks for any info!

[@novagarage38]

@@tsamonte Aliexpress does have buyer protection so if you have an issue with something you purchased, you should be able to open a dispute case and be refunded. I would try contacting the seller and asking them to send a replacement, I have been sent the wrong items before (albiet smaller items) and have had the seller send me a replacement, they are usually good about this in fear of negative reviews. I kind of found them on my own. I noticed that all the ebay stores and random proformance parts sites were selling the same exact spoiler, rebranded, so I just simply tracked down the source, I am familiar with aliexpress/alibaba as I've used them many times before for ecom suppliers. Once I found JPSportline was the manufacturer, I confirmed with them that HSpeed KSLine was a partnered distributer. They have also been on aliexpress for 9 years and have decent feedback, so its safe to assume they are legit. Scam seller will usually have not been on aliexpress that long as they get banned after enough complaints. Aliexpress is great, just be mindful of the sellers stats (reviews and years on aliexpress) which you can see if you click the feedback tab on the sellers store page.

[@tsamonte]

@@novagarage38 I'm currently in dispute with seller/aliexpress. Its so sketchy. Seller is not offering replacement at all. Only what I mentioned in my previous comment. Seller states he will refund my money if I return product as long as I don't give him negative ratings! I don't trust them at all so i'm trying to to negotiate the highest possible refund without having to ship back this useless spoiler I have! Its a joke! Lesson learned though.

[@novagarage38]

@@tsamonte Yeah, thats an unfortunate situation. I'd say something along the lines of I'm very disappointed that your company sent me the wrong item and now youre inconveniencing me with the hassle of having to return the item, and being how it was not my fault, and being whoever at your company sent me the wrong item's fault, I should not have to incur the return shipping expense. I am very disappointed with your customer service, your company should take full responsibility for the mistakes your employees make. Something along those lines to elicit fear negative review. It's most likely its not worth it for them to pay the return shipping to China and they'd just refund you. What is the name of the aliexpress store out of curiosity?

They have impressed me with a f80 carbon fiber engine cover. It doesn't looked bad at all woth my rk titanium charge pipes

[@markyazurin6304]

Hi, was wondering what size and type of washer and screws did you use? IS there a specific type or name for the side piece screws I want to get the correct and same ones you used! Other than that great video!!

[@novagarage38]

Thanks dude. They’re #10 3/4in self-drilling screws and #10 washers, I believe I got them at Lowe’s but I’m sure Home Depot has the same ones too. Check at 3:45 , I show both packages if you want to screen cap for reference.

[@smithy423]

Great video. Does the boot foot sensor still work?

[@novagarage38]

Thanks! For the most part it does, maybe a little harder to get it to pick your foot up. I notice when I'm trying to use it I have to kick around a bit. But, of course when I am not trying to open it, say when washing it, it will be super sensitive lol.

[@autobothaus6903]

Shipping brings cost to 399.00. Great vid.

[@novagarage38]

Yeah, they seemed to raise the price a bit as of late, still a great deal though, they usually sell for $500+ with additional shipping cost.

[@waltercheung9804]

Great vid! Who is the seller on Ali express of your diffuser? Was shipping to the states long? I live in Canada.

[@novagarage38]

Thanks man! The link in the description is directly to the seller I purchased from. It took about 20 days to get to the US Mid Atlantic Coast.

[@swiggityswag7866]

What size screws did you use for the side pieces? looks like 1/2?

[@cozee69]

At 13:41, is that a gap between the center portion and the rear bumper? When you were outside with the car it looked great. Just wondering if it’s the angle or what.

[@novagarage38]

Theres no gap at the center, at the edges it tapers to the edge so theres no gap towards the back on the edges but it does pull away from the edge of the bumper as it tapers towards the rear.

[@sjlnmusicmix1780]

How is the sound on the go, like do you have some awkward noises coming from the diffuser? Is the left side sitting well? Thanks!

[@novagarage38]

Not at all, no rattling or any sounds. As long as you install it properly, it's pretty solid.

[@reifyywaa2277]

how long did it actually take to arrive, and also did the side carbon pieces come with the diffuser? Thank you again!!!

[@novagarage38]

About 20 days to the mid-Atlantic USA. Yup, the side pieces came with it, made sure you select the option with the side pieces because you can buy it without as well.

[@ilginuzzo2635]

super clean, where do you get those rear carbon side extensions?

[@novagarage38]

Thanks! The side pieces are part of the diffuser, they are included with the kit.

Nick Nova Garage do you know if they are sold separately by any chance? And thanks btw

[@novagarage38]

@@ilginuzzo2635 NP. On the site, they sell the main part separately if you dont want the side extensions, but theres no option for just the extensions. Worth a shot to shoot them a message and see if they'd be willing to sell separately.

[@lav773]

Was yours hitting the exhaust?

[@elliottdavies8177]

Did you have issue with the centre part hitting the exhaust muffler as have a friend and his hits

[@novagarage38]

Not at all, mine cleared with no problem, but thats usually a simple fix by loosening the mufflers from the exhaust and repositioning, I've had to do that on other cars I've owned.

[@victorlee2902]

How is the piece holding up now? Are you having any issues with it at all such as the carbon cracking?

[@novagarage38]

Looks exactly like the day i installed it.

[@thaebalwaisi3307]

When u when drilling the side part where we’re u drilling them in too

[@novagarage38]

To clarify, are you asking if I was drilling pilot holes? I did not drill pilot holes, I positioned the side pieces, held them in place with painters tape and then used self tapping screws.

[@MB-js4us]

@@novagarage38 I think he was asking if the screws get drilled into body metal or just plastic... I was wondering the same thing. Thanks for the awesome video!

[@wilmimunoz4524]

Does your trunk open with the kick and that diffuser

[@novagarage38]

It’s definitely less sensitive with the carbon fiber one, probably to the point where you wouldn’t bother to use it, though it’s a gimmicky feature anyway imo

[@autobothaus6903]

Since install how is it holding up? Clear coat, rock chips?

[@novagarage38]

It has held up really well, looks the same as when I got it. just wax it when you wax the car or give it a nice ceramic coat and it's good to go.

[@samouraitrading3665]

I have the same diffuser but totch the muffler and i cant screw it do you have the same probleme ??

[@novagarage38]

No, but mufflers aren’t always installed perfectly from factory, you can try loosening the bolts where the muffler mates to the rest of the exhaust and adjust the tips down more on the hangers.

[@BosaFTW]

Is your trunk spoiler lip also from the same seller from Aliexpress? I need some carbon parts and thinking about ordering everything from this seller on aliexpress.

[@novagarage38]

No, the spoiler is the BMW OEM, but judging from the quality of the diffuser, I’m sure their spoiler is pretty good too.

[@wesameghneim2597]

i was trying to purchase the rear diffuser you said you got it for $320 with the shipping correct ?? because i got $400 i also live in the US

[@novagarage38]

Yes, I paid around $320 back in October 2019. It looks like they increased the price of the unit and the shipping, most likely because of increased demand or because of price changes with the pandemic. $400 shipped is still a steal for this piece though.

[@wesameghneim2597]

Nick Nova Garage one more question does the carbon fade ?? Thank you

[@novagarage38]

@@wesameghneim2597 Mine has not faded at all, they state the resin they use is UV resistant plus most waxes, sealants and ceramic coatings usually offer UV protection on top of that. It should not be a concern as long as you take care of it.

Yes, all the holes are predrilled, really easy to install by taping it in place and using self tapping screws for the sides and the main piece holes match the OEM mounting spots.
