Will the diffuser scrape on the ground and over bumps/hills?
If your GT-R is lowered, then scraping is possible but rare. If your front clears a bump or incline, the diffuser will too. Our GTR diffusers and bolt-on fins are the most durable on the market.

How difficult is it to install the diffuser?
It’s very simple. Check out our installation video and see how easy it is. The diffuser is a direct OEM replacement. Take your old diffuser off, save the bolts and attach the Difflow diffuser. Sell your old diffuser for a profit and make money off the whole swap!

Do you provide instructions and hardware to install the diffuser?
Yes we provide instructions and beautiful black replacement bolts for your new diffuser.

How long does it take to receive my diffuser after I order it?
If the diffuser is in stock, we usually ship on the same day. 48 hours at the most. If we are out of the diffuser you ordered, then we take aprox 1 week to build and powder the diffuser. Once everything is done, we’ll provide you with a tracking #. We ship FedEx ground, but we can ship faster if needed.
