Really pleased with this diffuser...this is the 3rd part I've bought from bulbexpert. The holes lined up exactly as they were supposed to for the center piece. I took the old one off and installed this one in maybe 20-30 mins. The construction feels very solid and sturdy...even better than the other CF parts I've ordered from bulbexpert.

I did look for issues with the weave and the only issues I saw were around the mounting tabs but no one can see that anyway. Some scratches in the clearcoat on one of the mounting tabs as well but once again...this is underneath the car and covered by the side pieces.l when installed.

The side pieces I used 30lb extreme 3M double-sided mounting tape to attach. Everything is installed now and feels solid, doesn't move one bit.

Highly recommended...10/10 for fitment and 9/10 for finish due to the scratching on the tabs/weave pattern. Packaging was extremely well done and shipping got to me a day early from CA although I'm in VA.

Here's a link to some pics:

Nice. Question, is the middle piece of your diffuser loose and swing back and forth when pushed? Or is it pretty solid and stays in place? I have a similar style diffuser from a different manufacturer and it just hangs there somewhat loose.

Does not move whatsoever even when I pull on it

Why do all the aftermarket diffusers seem to be pinched towards the center of the bumper at the top of the diffuser? I haven't seen one good replica that has been straight. Does anyone know of one?

LOW4LYF · 03-27-2019, 01:12 PM

Wish they would fit somehow our bumpers

Quick question as I'm thinking of pulling the trigger. I'm assuming to install this, we replace the existing diffuser with this one right? Is it held just by 3M tape or are there screw holes in the OEM positions to install this with? Thanks!

jaspirr · 04-01-2019, 08:54 PM

So I've ordered a V style front lip from the bulbxpert guy that everyone in this thread is pretty pleased with. It says it comes with no installation instructions. I assume that means it comes with zero installation hardware as well. I saw someone else in this thread struggling to match some installation hardware with OEM parts.

Is there some sort of OEM front lip installation hardware kit out there? Or a list of what kind of hardware I need to buy? Thanks.

I bought those. Its honestly super cheap quality (what I expected) and the bottom of the skirts are essentially just the raw fiber underneath.

I thought it was full carbon all around but its just on top

but fitment is 9/10 and it does the job

Dumb question...I got these too. Does the end with the little nub go towards the back of the car? ... and the end that's even go towards the front? Hope that makes sense haha
