Q60 Lower Half diffuser
1 - 19 of 19 Posts
Don't buy those Southbay autoworks, jaliscos, markie bang etc etc diffusers. They are all garbage that they buy wholesale from Allibaba and resale them to people here willing to pay a high price for something not even made in-house. I purchased one myself and the fitment is garbage. Gaps everywhere no matter how much I played with fitment. Zoom into the pictures people put up and you will see what I mean. Don't throw cheap parts on your car.
Love your Seibon Diffuser, there are too many out there that look cheap w/ the LED light. Thinking of going this route.
Here's where I purchased it from:
Seibon TB-Style Carbon Fiber Rear Lip Infiniti Q60 2017-2020 | RL17INFQ60-TB
Yikes! Prices have increased. I paid $664 w/shipping back in November 2020.
I will take 10-12 weeks for Seibon to produce the diffuser.

these guys are pretty big in the Q scene can you recommend any manufacturers with serious quality
Yes go with EMM TUNING. they have been making quality Q50/Q60 parts since these cars first launched. They are pricey. But then again you get what you pay for. Everything is bespoke and made to order.
The only reason those other vendors are big is because their prices are cheap. And people like cheap. But honestly all the stuff they sell is resold stuff they bought from China on Alibaba. Nothing special about what they offer.
Here is an example of those poor quality diffusers going around the Q community with that rear foglight built in:
You can clearly see how the top part has a huge gap where the diffuser meets with the bumper. I too experienced this. The issue is that the diffuser doesn't replace the factory diffuser. It just sticks on with tape over the factory diffuser.

How was the install? Did you have to remove the front bumper? Was it pretty hard?
I think you meant rear bumper, but no, the only part that was removed was the stock gloss black valance panel. I push the upper clips out from the back of the valance panel, which attached it to the main bumper cover, after removing the lower push rivets and two screws on either end.
To install the Seibon rear diffuser, it has thin metal tabs that you thread through rear bumper cover eyelets (instead of clips), and then bend down, as the rear crash bar is right behind the cover. I used larger diameter washers for the screws on either end, and you have to push either end of diffuser inward (against the bumper cover) to make the bottom push rivets & holes line up for assembly.
Otherwise, it was a straight-forward install.

Thanks! And you were right, I meant rear bumper lol
No worries... and as you can see from my photos, the Seibon diffuser replaces the stock valance panel and it fits good (with a little push here and there while inserting the push rivets)
No doubt the fitment is spot on. Does the color and pattern match up perfectly with the oem CF?
Wait jk I think you already posted on my other post sorry
Seibon manufacturers some of the best CF pieces for the Q60, so go for it!Wait jk I think you already posted on my other post sorry
I know im back and forth on it. Might just grab the unpainted stillen one and do a paint match.

Yep. Price today is a lot more than when you got yours. To add insult to injury, shipping is $250
Great information on the diffuser and install.
Did you have to adjust your exhaust tips in or out vs. OEM valance?
I like a little poke
VIVID
No, the FI Tips were not moved from the OEM to Seibon Diffuser, but you could easily loosen the last pinch clamp and slide the muffler & tip assembly more rearward.

No. The upper tabs were bendable metal "fingers". The end caps had two screws each, just need larger-diameter washers, and then the plastic push rivets along the bottom.
