G4 ACR spoiler wing on SRT10

[96TTtrqmnstr]

If I wanted to install a factory ACR wing on my Gen4 base coupe what all is required to do that? Are all the brackets and mounts a direct bolt on affair to the chassis (other than drilling the hatch of course). Thanks for any details you can provide!

[z20ateU]

The ACR wing produces substantial downforce.
The stock rear springs more than likely would not be suitable at speeds over 100mph.

[96TTtrqmnstr]

I've read this and have also read a lot of controversy about this theory. For that reason I am strictly asking what is required to physically attach the spoiler please. I'd rather not re-hash the debate about the extreme downforce crushing the rear of the car so badly that it ruins it beyond mechanical use and State Farm must cut me a check for a salvage vehicle.
Thank you for that though!

I have been to 120MPH at 18 degree and no problems. This wing dose have base plates to distribute the load.

GTC-500 wing. That is only 500 lbs down force.

PartsRack can provide that wing, BUT:

....if you plan to add 500 lbs of REAL DOWNFORCE to your brick-like chassis, you better damn-well not poo-poo the need for SOME ADDED DOWNFORCE AT THE FRONT to balance the chassis at speed. FACT. If you go OE G4 ACR Wing as stated, its WORSE imbalance...


I can give real-time examples of owners at 130-150 mph travelling in AZ, NV, OR, and encounter a mere KINK in the wide-open road. Think Silver State Classic, and Pony Express 100 country....

What they dont realize is that the front tires get 'skinny' at the front as the contact patch is minimized by Rear Spoiler / Rear Wing add-ons.

They power thru the kink, but THE CAR STAYS STRAIGHT. Classic "UNDERSTEER" , already a noted Viper issue, now magnified by added rear downforce alone.

They OHSHIT panic, and lift off, diving the nose. The car now reconnects at front and DARTS in the direction they were under-steering. Most good drivers correct; some soil themselves. Some few lose the car.

Im not wanting any liability for a customer making a dumb, cosmetic move. So I wont sell just the wing withought a signed discalimer. I dont want to be sued by your estate.....

^^^^^^

True but hilarious

[pokeyl]

All correct, that is why I added the front splitter and 2008 KW ACR suspension front/rear. Some day I may do sway bars.

Downforce imbalance is just "theory", Jon. He doesn't want to re-hash the subject.

So is gravity, but why let little things like that get in the way of a cool lookin ride.

Pretty straightforward. If you do buy one send me a PM and I can give you detailed instructions from the Prefix manual that shows how to install all the ACR aero. Mike

Pokey, thank you. That looks very similar to factory shape etc exactly. I'm impressed!

Jon, thanks for the reply. I do appreciate your experience and opinion. The rear downforce setting the car off balance I can definitely believe to be true. I do have plans to do both the front and rear for this reason as well as cosmetics. I think the rear alone is a bit too aggressive to NOT have a front splitter. I'll keep you in mind when i'm ready to make a decision. Thanks again.

[96TTtrqmnstr]

Downforce imbalance is just "theory", Jon. He doesn't want to re-hash the subject.

I have absolutely no issue with a reply like Jon's with real life concerns. The topic I did not want to re-hash was related to all the claims of too much downforce that it will crush the chassis, crush the rear hatch, needing heavier spring rates, etc. (whether true or not) You may have misread my post?

[96TTtrqmnstr]

Thank you very much! I was hoping somebody would reply that has actually installed one. Much appreciated.

ACR's have different trunk struts too.

Pretty funny. How do you think I got the install manual??? Ebay??

[SA Heat]

Bruce

Yep....and as of a few months ago, boxes with the "non-ACR" SRT10 strut part number on them had the ACR part numbered struts inside. I tried to find SRT10 struts at several Dodge dealerships and with Jon B. All the same thing.

Nope, didn't misread it. But it looks like you may have misread the post @z20ateU wrote. He didn't say anything about crushing the chassis or hatch or the rear of the car. When you're talking about bolting a surfboard-sized ACR wing on the back of an SRT10 without all the bits that should be on the car with it (including coil-overs with the correct spring rates), the concern is about the way the car will drive/handle at triple digit speeds when hundreds of pounds of downforce are in play. I'm pretty sure that's what he was referring to.

[SilverACR]

It’ll be fine just toss a couple bricks under the hood.

lol. No I meant that sincerely! I was saying thank you and I'm glad I had somebody replied with real experience like yourself!! lol. Holy hanna.
Everybody's so sensitive around here.

Nope. I didn't misread at all. I already have coilovers here with different spring rates...which AGAIN, is why I have no interest in discussing this portion of the install. And again, this is a HIGHLY debated item which is why I don't want this thread to turn into another debate. All I asked about was the install process itself. You were the one with a smart comment mocking me about rehashing the subject with nothing valuable to add to the thread. It appears as though you have a bone stock viper so that explains why you have nothing of value to add. I will wait for the next thread you start asking about bone stock Vipers and be sure to add my $.02. Thx

You get your feelings hurt too easily. Lighten up a little.

He has a bone stock Gen IV ACR, which has the exact wing you want to put on yours. There is a reason the bone stock ACR was designed differently than the regular SRT10. There is a reason the ACR is reinforced.

I couldn't care less what mods are done to your Viper. You have never owned a Viper with an ACR wing, or an ACR Viper. So there is a good chance a guy with a bone stock ACR is going to know more about the aspects of the wing than you.

[SilverACR]

I’ll qualify some things here and painfully admit I too have a stock ACR problem;( the stock ACR going into a high speed kink does have significant front end lift that needs settling with a little tap of the brake to shift the weight even with aero to plant the fronts for the most efficiently to hit the turn without pushing the front through the turn. On the exit of the turn the backend squats with the aero that help to keep the ass from going around. Now... if you’re not tracking the car on a road course and doing straight line stuff I seriously doubt a wing on the back is a concern as you will just keep pushing the back down throughout the run and as long as you don’t do anything stupid or it’s not super windy you’ll be ok. If you will be challenging a road course or ripping high speed canyons then take the aforementioned warnings seriously. You won’t crush the car you’ll find oversteer and understeer unmanageable at some point and none of us want to see a viper owner hurt. Yes a lot of smart asses here including me with the penny car (miss those things) but, but, we actually care. No need to internet fight just think...
