Maxton Design Diffuser: Kpeng Improved

[tlr1000]

Two updates. 1. The diffuser does nothing to keep the back bumper skin and trunk hatch from getting fouled in bad weather, driving on dirt roads, salt flats etc.

2. Efficiency and aero appear unaffected OR actually improved a marginal (almost immaterial, within error) bit. Drove the car as I usually on a 1.5K mile road trip. Mostly highway, some rural roads, lots of mountains (including scaling Mt Washington as the first car of the day) and seeing the same per trip and avg Wh/mile and 100% SoC guesstimated range as before.

Fun fact - Driving up Mt Washington, used up approx 10% SoC on a cool July morning at 8AM. The car was completely unphased by the grade and climb.

Coming back down, with regen on high, gained back 9% SoC and never had to touch the brakes... in fact a few times I had to use the accelerator to keep the car from stopping (lol).

Thanks for the update.

1. As long as it doesn't accumulate dirt faster than before, I'm good.
2. Again, happy that there's no negative impact on efficiency.

Car is looking good. Did I tell you silver is the best color?!

Looks great! Thanks for sharing your install tips, guys! I think you've helped me decide to go with this mod.

I would love a functional rear diffuser that could replace the stock panel.

I found this diffuser that replaces that entire rear undercarriage tray, but it's pricier plus larger piece so steeper shipping. It does seem to protrude beyond the rear edge of the bumper as well.

You mean the one I have been looking to sel since Winter:
FS: NY NJ CT Revozport Model 3S ‘Strasse’ Rear Diffuser

Its also mostly, if not purely, cosmetic.

 

[tlr1000]

I like the idea of replacement vs add-on but don't personally like it protruding so that part would be a deal-breaker.

LOL...didn't realize that was you. If you were local, I would've bought it!

Any of you guys installed the v1 lip? I think that’s the cleanest lip I’ve seen the for the model 3 by far.

 

[Perscitus]

Yup there are a few on here and elsewhere who have.

Mine is on order, ETA mid August.

Thanks for the detailed photos. It looks good overall, but that gap along along the whole rear would bug me. Wish it was more flush there...

 

[Perscitus]

Its flush, the gap you are seeing is likely more of an optical illusion than anything else.

Or perhaps you are talking about the curvature along the passenger's side , which is a tad off. Still no gab just the leading edge of the diffuser is showing.

It is what it is and as good as it gets with plastic fantastic accessories and OE piece fitment.

Where can I buy this kpeng edition of the diffuser?

 

[Perscitus]

You can't, you have to make it yourself.
kpeng is a member on here and you can see what he did to modify the stock Maxton Design unit.

Else, if you want the default look, just order one up from your regional Maxton Design distributor (US, Canada, UK, Poland, etc).

I'm not funny, I get it.

 

[aspec818]

So what I’m gathering is this whole mod is unnecessary...

 

[Perscitus]

Indeed. Personal preference and a compromise, as with almost everything else on here.

Not talking installing the diffuser itself. But cutting and modifying the edge. It doesn’t protrude out when installed as is I’m seeing.

 

[Perscitus]

Correct, I understood what you ment first time around. the kpeng mod is the personal preference I had in mind.

 

[kpeng]

I just do what I want.

 

[aspec818]

Well it looks like kpeng got banned. Wonder what happened lol

That's unfortunate. He can be quite abrasive and receives/gives a lot of thumbs down...maybe that factors into it? Who knows. But, I am thankful he created this thread and shared insight with the community.
