Just throwing this out there in case anyone has one they'd be willing to part with. Ideally, a damaged one would be even better, as I only really want the license plate mounting bracket.

It's this one here: http://www.renntechmercedes.com/inde...ing-lpm-detail

PM me if you have one. Thanks

Free bump. So there's a 7.4L in that beast?

Also curious how that mount location would hold up at high speeds. The bolt holding on the plate bracket is tiny.

BLKROKT

I thought the same thing until I read the installation instructions (the pdf is now gone with their new site layout). The bolts go all the way through the trunk, and have backing plates on both sides. It's not flexing or going anywhere, and the forces from the wing push the bracket forwards against the license plate area (not down). It looks pretty stout.

The price on the Renntech is horrific.

Some CNC/plasma cut and welded aluminium?

BLKROKT

Yeah it's pretty obscene.

Getting all that cutting and welding right would take way more trial and error than I need right now. If I don't find one before winter, I'll tackle it then.

tpliquid

doesnt look like it needs to be welded. just laser cut then use a brake to bend it.

BLKROKT

Appreciate the responses, but you guys aren't seeing the entire thing. There are mounting plates perpendicular to the uprights, and those would have to be welded. The support docs are now gone from the Renntech website, but they were very illustrative of the whole thing. They did a good job on the engineering, as you'd expect.

I was just going to bump this thread today, when I finally got what you were saying.

Something roughly like this, folded with a brake at the license plate bracket. Looks like a Transformer head now, but folded, it looks like the bracket in the pictures above.

Doesn't look too hard to do, will need to collect some cardboard for templates so I can get the size/shape/angles right.

Thanks for the idea! Does anyone have a good contact for a place that can do this if I send them an AutoCAD or something? And would 3/8" thick Aluminum be ok, or should it be made out of steel?

tpliquid

give me the measurements and i can draw it up for you when you are done mocking it up.

Moving to Japan?

What the fxck $4k USD for a rear wing from Renntech?

Hey Rokt,

My sisters hubby is a machinist at a machine shop and specialize in prototype stuff. If you get it in a CAD 3D, I could put out the word for you. He's a car guy too. Let me know if your interested.

BLKROKT

Thanks dude. I taught myself AutoCAD a couple years ago, and it was apparently good enough for my carbon diffuser things to get made. Could always use help though, appreciate it.


Haha, no I'm not HIRO. But I do need way more downforce for high speed corners on track - car is getting too light and sketchy for my liking. But I want to be able to take it off and not look like an idiot when I'm not on track. So this is the answer.


Yeah it's stupid. I can probably get it made for 1/2 as much. The APR wing I want to use here though is like $1500.


Thanks JD - let's talk about it for sure. You down for this too?

NotABaller

Definitely interested in getting a wing too. It looks great.

BLKROKT

Stay tuned then

JeffDL

no it's the standard 6.2 the 7.4 is something to do with how wide the track is or something strange like that.

I'd think with just the plate mount that wing would be super bouncy. other wings that i've seen like that are chassis mounted and you can stand on the supports.

most of that renntech kit was super *****ty it had a great name or backing but the kit was horrible.

jd_hinks

Lol always down for a performance DYI

BLKROKT

Hmmmm. Good point. The idea was to have something removable, and the chassis mount wings definitely are not. I wonder if a couple of removable supporting brackets (or extra links/buckles like in the picture) could be attached to the bracket and go to the front corners of the trunk lid.

Will rethink, thanks

Jasonoff

If that rentech wing mount is not wind tunnel tested I'd stay away. Or unless it's actually used in competition.

Even with a rear mounting plate to sandwich it, I bet the rear wall of the lid would still flex.

jd_hinks

IMHO I think if it were anchored at and thru the back of the trunk lid with a rigid enough brace, given material used(aluminum and carbon fibre) I don't think a little flex will matter all that much.
As long as you can adjust the wing to compensate for if any flex at high speeds.

For a product like this to serve as a weekend racers spoiler with the ability adjust and install when racing and remove when back to DD is a good idea.

Yes the only way to truly set up any aero component would be to wind tunnel test. This can really only be done on a car by car basis.

Here is a sweet you tube link about wind tunnel testing spoilers and canards I came across a few months back.

What about a black series wing mounted to another trunk? Swap trunks for track days, swap back for street driving?

kjkidd21

THIS... or just mount a BS wing to your current trunk and call it a day.

I think Blk might be dead-set on having it be removable and provide even more downforce than the BS wing...

WHOOP! There it is.

Interesting.....

However I found one on eBay last week thanks to Kriston. It gets here tomorrow. And it was only $1000
