BMW M3/M4 (G80 G82) CARBON FIBRE WING - MP STYLE

I purchased this carbon fibre wing. The 'MP Style' in its name led me to believe that there wouldn't be significant issues with installation, and I expected a premium product that would align with BMW's M Performance aesthetics and general fitting standards. However, this was far from the truth, and the product description is severely lacking in crucial information.

Upon arrival, the spoiler had visible glue residue on one of its inner edges. While this was a quality control oversight, CT Carbon offered a 15% partial refund, which I considered a nice gesture, thinking a professional detailing studio could easily handle the stain. So, that specific issue seemed manageable at first.

However, the real problems began when it came to installation. After receiving the spoiler, I asked CT Carbon directly if the bolt holes and support brackets were identical to the OEM M Performance spoiler, aiming for a direct fit. They completely failed to provide any clear answer on this vital pre-installation query.

The most critical issue, which the product page completely fails to mention, is that this spoiler does NOT fit standard OEM trunk holes. Despite being marketed as 'MP Style', the spoiler is actually slightly wider than the original OEM part and has a completely different base hole spacing. This means no OEM mounting kits will work with it, and you absolutely cannot use standard OEM mounting points. Furthermore, CT Carbon provides no mounting hardware whatsoever, stating 'we don't provide the mounting hardware for these as so many places mount them differently,' leaving customers to source essential components and figure out a complex installation process entirely on their own. It quickly became clear that a specific mounting kit was absolutely necessary to install this spoiler, but even with that, the base didn't align with OEM holes. While I understand that an additional mounting base might be needed for certain aftermarket parts, this critical information (that it doesn't fit OEM and requires a special solution/kit that also doesn't align with OEM holes) is entirely missing from the product description.

The lack of transparency regarding the non-OEM hole spacing and slightly wider dimensions led to significant problems during installation. In my case, a mechanic, expecting straightforward compatibility given the product's 'MP Style' designation and CT Carbon's complete lack of clarification, proceeded to drill holes in the trunk based on OEM measurements. While this was ultimately a mistake by myself and the mechanic for not double-checking the measurements before drilling, this costly error could have been entirely avoided if CT Carbon had provided precise, explicit information in the product description, or responded accurately to my direct questions.

On the very day of installation, due to the complete incompatibility and the issues encountered with the CT Carbon spoiler, I was forced to purchase a brand new, genuine carbon M Performance spoiler that does fit the existing OEM holes to match the newly drilled holes in my trunk. This was a significant and unexpected additional cost. It's truly a shame, because I genuinely preferred the CT Carbon spoiler's aesthetic – its wider design looks far more aggressive and awesome. This unfortunate outcome was incurred solely because the CT Carbon spoiler did not fit as implied by its name and as expected based on their lack of clear warnings and failure to answer crucial questions. Ich poor communication effectively prevented me from using a product I actually liked more.

Consequently, I requested a refund for the CT Carbon spoiler itself, as I now have no use for it. However, to this day (July 8, 2025), I have received no response from CT Carbon regarding this refund for the unusable spoiler.

If you expect a straightforward installation based on the product name, or rely on accurate pre-sales information, look elsewhere. This product caused immense frustration, unexpected additional costs, and a prolonged installation nightmare. CT Carbon needs to drastically improve their product descriptions to be transparent about what's actually required, including explicit details on dimensions and hole spacing, and respond to pre-purchase/pre-installation queries about fitment, especially when using terms like 'MP Style'."
