2011-2016 BMW F10 M5 VSX Carbon Fiber Rear Diffuser
About the BMW M5 VSX carbon fiber rear diffuser:
The PhaseCarbon BMW M5 VSX carbon fiber rear diffuser was designed specifically for the F10 generation BMW M5 super sedans.
With quality and fitment in mind, we wanted to bring only the best to our fellow enthusiasts, so if you've been considering this upgrade but something held you back from pulling the trigger, we believe we have the answer for you.
When you shop with us, you can buy with confidence that you will be getting a top notch product backed by incredible customer service and a money back guaranty.
We stand behind our manufacturer, our products, and our QC process to ensure that you are getting a spectacular hand-made product that looks great and fits great.
NOTE: If you have the M Sport rear bumper or one of our PhaseOne rear bumpers on any of the other F10 BMW 5 series (non M5), you can also replace the rear diffuser with this one. You will however need to modify your exhaust to accommodate the quad setup. Don't worry, we have you covered on that front as well.
We are typically very quick and have a 24-48 hour turnaround time. Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other.
Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)
Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at firstname.lastname@example.org
Yes, we do price match reputable competitors in the marketplace. If you find a product cheaper elsewhere, please email us the (1) link of the product from our website and (2) the link to the competitor site. We will make an assessment on our end if we are able to price match or not and respond to you via email.
Typically you have 14 days to return a product you purchase when you change your mind. Damaged and improperly installed products are NOT eligible for returns. Shipping fees may be assessed and not refunded based on criteria as well as restocking fees. Please see our FAQ page for more details.
Unfortunate Kies Motorsports no longer does customer installs (with the exception of crank hubs - we still do thos inhouse). Our HQ is solely reserved for filming, office space, and shipping/receiving.
