The MHC+ BMW F80 M3 and F82 M4 aggressive 3-piece rear diffuser is the ultimate rear diffuser upgrade for F8X vehicles, manufactured from pre-preg carbon fibre. This carbon diffuser has OEM BMW quality and fitment with a stunning carbon fibre weave that matches that of BMW Carbon. This diffuser is easy to fit at home - alternatively, we offer expert UK fitting at our London-based workshop.

Why choose pre-preg carbon fibre?

Unlike normal carbon fibre, pre-preg carbon is reinforced for increased strength and durability. It can also be an astonishing 70% lighter than other carbon options, ideal for weight-saving. Quality-wise, pre-preg carbon is far more consistent meaning the chance of imperfections is dramatically reduced. The manufacturing process eliminates undesirable air bubbles and results in a perfect, sleek, smooth & high gloss finish, making the ultimate part to complement your vehicle. 

When you buy pre-preg, you are investing in a higher quality, longer-lasting part that will outlast other forms of carbon fibre and potentially save you money in the long term.

*Please note: The bumper will need to be removed for installation and the heatshield may need to be altered due to the aggressive design of the diffuser. We offer expert fitting at the R44 Workshop - email or call to book in. Click here for our contact information.

He loves it! It will probably be destroyed soon though...
Size: For Medium Dog, Color: Green, Size: For Medium Dog, Color: Green
Update! This toy has definitely withstood my boy's daily chewing! It's lost some pieces for sure, but overall it's holding up and I'm very happy about it. The only downside is the squeaker is rather difficult to get to make noise. Will still definitely invest in another when this one finally goes. Original review: I bought this for my handsome pitbull/boxer mix -- the boy loves to chew toys up! He's an aggressive chewer and he was bored with the current toys we had. This toy is advertised for chewers, and I imagine if my boy wasn't such a great chewer, it would be amazing! We've had it three days now and he's already gotten a few big chunks off of it. It is definitely entertaining him though! He loves it and he seems like he's chewed himself into a daze. There is a squeaker in the bottom that seems difficult for him to get to so it doesn't squeak often -- when it does though he freaks and it's hilarious. Overall I'm very happy with this purchase. My boy is a very aggressive chewer and I know pretty much anything we get him will be destroyed soon after he gets it. With how much he is enjoying this toy, I will be buying it again for him.

Outstanding Chew Toy
Size: For Large Dog, Color: Green
My dog is beyond an aggressive chewer. Toys are in pieces in minutes no matter what the manufacturer says. The squeaker? Forget it gone immediately. She has had this toy for two days and not only is it intact but she hasn’t been able to remove the squeaker!! Great product!!!

Be careful. Prices come off
Size: For Medium Dog, Color: Grassgreen
My dog loves it but it does come apart. He’s not a dog that destroys things but he bit prices off of it.

Heavy duty
Size: For Medium Dog, Color: Green, Size: For Medium Dog, Color: Green
I just unboxed this so I will update if my opinion changes. I bought the medium dog toy, it’s a a great size, perfect for my 110 pound lab and my 60 pound pit terrier mix. It’s heavy duty so I don’t see this being torn apart anytime soon, it has a slight mint scent (mostly rubber). As of right now, I can confidently say that I see myself buying more from this brand. Hopefully it helps with their stinky breath, if not then at least it’s a fun toy for the pups. Update: after over a month of play I can say it’s still going pretty strong. My dog did manage to damage it a bit but if you have dogs who are rough on their toys, this is a good option. I was also surprised to find out that there is a squeaker in the base of it, the pups have to bite really hard in order to hear it, heavy duty toy. I will say one of the only downsides is that it doesn’t seem too appealing to my pups. If there are other toys around they’ll go for the other toys but occasionally will pick this. I still recommend it. Has been lasting us awhile (I have 3 pups).

Dog ends up eating plastic ends
Size: For Medium Dog, Color: Grassgreen
At first I thought this would be a great toy but in reality the design doesn’t make sense. The little pieces ‘pricks’ of the cactus get chewed off and swallowed by the dog. So you’re essentially feeding them plastic.
