Installing RSNV Wing Risers On The 718 GT4 

hamann 😂

RICARDO More than confident in our price, as are our customers. Compare around and you’ll see.

RICARDO it’s called Porsche tax

There’s #’s posted by pro drivers available. You don’t need to pretend to be some racecar driver to find out the potential. Let the car nerds beat up their cars

@@mperformance3502 That sounded ridiculous

@@mperformance3502 real cringe

Lol wannabe race car driver nerds

@@mperformance3502 lol. The only wannabe is the person that dresses their car up to look like a race car, but doesn't use it. Thats you

Matt needs a wing like a chicken needs a suitcase

Definitely 😉👍🏼

Great tip, that’s what we typically do. The bolts are light enough to not really damage anything but washers get lost easily!

Hey, Reezy didn't expect to see you in here! Hope all is well.

🙌🏼

Have you had it in a wind tunnel?

@@jamesbaggaley1460 exactly, Porsche spent a lot of time and money to dial in the front to rear downforce balance so if these actually do increase rear downforce, what are you doing to the front to compensate? BTW, I doubt they really do much and it’s highly likely they reduce downforce. If someone has done a wind tunnel test then I’ll stand corrected. Otherwise this is purely cosmetic.

Also 40 and agreed. I am getting old.

Agreed, factory height is perfect

Raising the wing 3” inches had no discernible impact on downforce. Takes 6” rise to get the wing above the roofline and then turn the angle using the 3 degree hole option, then you get downforce. The RSNV are cosmetic.

Onlyfans

Alex gotta be top 1% for sure

Happens time to time! Seems more often lately. Is yours a 718 too?

@@rsnv_co Yes it was a 718. May be helpful to put a note in the install directions. Other than that it is a great product, and easy install.

It will be just fine the way it is.

@@ObsessedGarage but it will affect the super long 2-5 gears now! :)

Only if Matt changed the angle of the wing. If so, Porsche says remove the front diffuser blocks, not the screen. If you want pics, let me know.

Unbalance in terms of aero/downforce? No, because this is simply a riser kit. Assuming they don't change the angle of the wing, it'd have 0 effect on the downforce. It might be a little better in terms of air flow though - potentially cleaner air the farther up you go above the car (ie. why you see some race cars with wings mounted 2 feet above the trunk).

😂😂 pretty sure it’s fine

Only if you use the 3 degree angle adjustment on the wing hardware. If you use the higher angle, Porsche sys remove the front diffuser blocks. I can provide pics if you need them

Upon further research, the 3” increase in height of these risers has NO discernible impact on downforce. If you do not get slightly above the roof line, there is not much additional air hitting the airfoil to create downforce. Getting slightly above the roof line and using the Porsche provided hole on the upper rear bolt (the lower cutout) that rotates the wing forward at the leading edge creates 3 additional degrees in the angle of attack, creating substantial additional rear end downforce. The RSNV risers are, therefore, cosmetic (but if when you do mount them and you use the Porsche provided hole, you will get additional downforce, just not due to the RSNV risers, rather due to the increased angle of attack). Aerodynamics and math for friction coefficient and drag, it ain’t that complicated. Just like a wing on an aircraft, differential pressure. Again, with the 6” rise and the 3 additional degrees in the angle of attack you must remove the front diffuser blocks to balance the car. Removing the front diffuser blocks creates the front end down force necessary to plant the front of the car and balance it. If you do not remove the blocks, the air flow in and through the front end does not change and the wing angle creating rear end downforce will create front end lift, just like an airplane, At speed, the imbalance can, under the right air flow circumstances, can be enough lift to create imbalance. Imbalance is always potential disaster. Think of a heavier person on the end of a teetertotter, Most will never see the difference unless they track it, but it is discernable on the track. Since I am not an aerospace engineer, I strongly recommend anyone doing this consult Porsche and reference the booklet that came with your GT4, which does discuss the necessary adjustments for the additional downforce. DO NOT USE MY EXPLANATION!

Mid engine>rear engine IMO, and now they are actually sexy

A week is a good idea.

Obsessed Garage cool, thanks!

Yes a lot! He mentioned that in his livestream. 👍🏼

No but looks cool at the grocery store

Looks like it ended up right to me - the rounded nut is on the inner side, flat top screws from the outer side.

But will he check 😜

Small increase in downforce and decrease in drag. +5lbs downforce @ 80mph, about a +20% increase of the stock wing. Less turbulent air.

Would love to know who can make these for us for $5! 😂

I don’t think most people think those look comparable at all.

And therein lies the reason for options. Form, fit, function, performance, looks. Looks rank last on the list and.one has to get real close to see that difference. And while most might like logos on their stuff, honestly, Porsche should be the only logo on a Porsche. Your product is quality and I appreciate that, but it is not worth the 66% price difference when looks is the only variance that differentiates it.

Wes Smith If it’s not for you, it’s not for you, no problem. But those extenders are worthless to most owners. Full risers feel OEM+. Those are hacked together. Honestly, their margin % has to be higher based on the simplicity of manufacturing those. No hate towards them, just different buyers. But we’re fully confident in our offering and our buyers are our biggest fans.

It is absolutely worth the price difference of that option. Those would never go on a car of mine.

If stuff you sell is all you advocate for, that’s cool. Your really just a store and not an enthusiast. I guess your partner Soul should stop giving you stuff since they rep auto quest also.

I doubt that. It cost way most to make these than that.

Far higher. They’re much more complex than you’d guess until having them in your hands. Look at how we compare to our competitors on price/quality. We sell direct to consumer, no wholesale to cut out insane markups. They are 5-axis CNC’d from billet 6061 with extremely high tolerances - nothing is straight, everything is angled from the mounting holes, to the angles of the riser, to perfectly meeting the wing mounting points and maintaining AOA. Until you look at the car you’d think everything is just straight, but it’s not. Quite a complex shape.

RSNV I’m sure your staff would like their paychecks and benefits to continue as well!

Paul Farmer Gotta make some money to keep us going and make more products! Exactly. 👍🏼

The magnetic box is the difference. I’ll take mine in bubble wrap!

Julian 987R They definitely don’t care.

It does not void the warranty. Heck the dealer would install this if you needed them to dot it.

He’s an amateur driver like yourself. Every mod us amateurs install are race boy mods. Unless your a professional driver, which I doubt

I would be surprised if it made much difference in downforce/balance given the angle of attack hasn't been changed.

dont be jealous
