Is there a reason you want a license plate mounted wing as opposed to a "regular" wing that you'd mount on your trunk? Is the thought to remove it for DD duty and just install for track days?

 

Yeah mostly because I think wings look stupid on a street car. Plus I want to keep my big carbon RNT wing on there that I have now - I have some ideas on how to pull this off. I think this might actually be more effective back behind the car a bit like that, vs the BS wing.

All sorts of reasons, but mostly so I can take it off and not look like a ***** driving down the street.

 

Gotcha. All good reasons.

 

How would you guys feel about an aftermarket "active aero" dynamic wing? Wing stays close to trunk at low-mid speeds. Then goes up once car is at a higher speed. Would this be a good pet project? I think I (and some engineering buddies working in schools) can hook up the car's speed to a small microchip that raises/lowers a hydraulic wing. I guess the real challenge is making it resemble an AMG quality product and not a hacked-together school project accessory.

 

See this thread for some ideas. https://rennlist.com/forums/racing-a...e-of-time.html

In short, if your active aero wing fails at an inopportune time on track, it's going to send you into a wall. That's why it's banned in most forms of racing. No disrespect, but I'd hardly trust experts like Aeromotions with it, never mind a bunch of amateur engineers.

 

They're probably selling because it doesn't work lol

 

Thanks, good read.

 

Yup.





Needs some work to fit - no mounting plates or hardware - but looks like it will do the job.

 

How light is it? Looks sick!

 

Yeah I'm pretty happy, thanks again for the tip on that auction.

It's light. 8.5lb all in. Couple of pics below. The carbon weave is gorgeous and mirror-like. This is kinda dirty too, and should look amazing once cleaned and properly waxed.



1. One thing I'll have to change are these turnbuckles. The body is plastic and has some sort of horrible possibly fake carbon wrap around it. The end adapter things are cheap, not tight, and not very secure on the ends either. The DIY endlinks project gives me some ideas here, and I'll order the parts later today. I think I want more adjustment on the wing angle, because it doesn't currently sit high enough over the back (from pics) to be truly effective IMO. If I can make more adjustment on the angle of attack, it looks to be an effective enough airfoil shape where it could help mitigate the height problem. I think.


The other things I need to figure out are:

2. Notch/shave my rear trunk carbon wing in 2 places to allow the aluminum wing support scaffolding to sit inside. Maybe put some sort of notched rubber bushing in there to help absorb any movement of the supports, while also giving it some lateral support itself. My carbon trunk lid wing is much bigger than the one in this pic where the supports are almost touching it, and the notches will likely be 1-2" deep. I imagine that it will also help direct air closer to the underside of the Renntech one. In theory.






3. Fabricate a mounting plate/method. I think that the mount works just by throwing bolts through the license plate area and into the trunk to a mounting plate inside the rear hatch trim. I don't know if I like that, and it's hardly "removable". I might fab a support plate that anchors to the inside hatch structure, and then has big studs that exit out that license plate area through another support plate, then there would be nuts holding the wing support on. Big nuts.


I'm starting to sketch things out. Am I over engineering this? Probably. This is going to be an interesting one though. .

 

Yup

Tired. Will explain tomorrow. It was a lot of work to get it mounted the way I wanted it.

 

Looks sweet, but what's the story with the California plates?

 

Thanks!

I bought my car in CA and drove it out here. CA keeps allowing me to re-register to my home address in NYC, so I let them (especially because they let me switch to the custom black plate a couple years ago). And I've been pulled over enough times to know it's fully legit. My 6yr CA emissions exemption expires next year, so I assume the party's over then...

 

That is looking nice - I'll be interested in hearing how it performs for you. Nice Magno Night Black G wagon back there too

 

it looks sick. how stable is it? does it bounce with the mount point only being the license plate? or is it light enough so it's solid?

 

Thanks guys. I'll take more pictures of the mounting after work today. I ended up putting 4 3/8" stainless studs through the trunk, then a 1/4" T6 aluminum plate directly behind, and another one attached to the scaffolding inside the trunk over where the trim attaches. It's not going anywhere, and I can put as much weight on the wing as I could without damaging the surface. Side-to-side stability isn't great, but I have some ideas on how I might fix that.

Also made some new turnbuckles with stainless ends (from a yacht parts supply shop of all places), and it gives me another 3" of rear wing lift/tilt if I need it.

Overall pretty happy, and the wing is much wider and sits higher than I thought it would. Should be effective.

Oh, and it's not removable. Like, at all. But the wing comes off which doesn't look bad actually.

 

Looks great.

Interested to see how you installed it in detail.

Car cover fits funny now. My wife said people are going to think Batman lives here.

 

That last pic is epic.

 

Yeah thanks. This angle makes me laugh, it reminds me of a profile for an old CanAm car with the cover on LOL. The wing is huge.

 

Looks awesome im sure it will benefit you on the track. Nice fab work!

 

Looks great Blkrokt. It looks like it cleared your other spoiler, and you didn't have to put 2 notches in.

 

Good job with the install! The spoiler set up looks choice.

 

Wing is starting to grow on me. Got the angle dialed in better. *** end feels more stable already.

And the wing itself is super stable. Doesn't bounce around a bit.

 

Wait, I'm confused. So is this the renntech one you bought off of ebay or some other place?
