Wheels wheels and wheels again

Yikes. I guess for that money you could buy a few sets of ACR wheels in 19 all around. Similar wheel but only black of course.

ACR wheels are heavy, they look good, but do not compare to the lighter aftermarket options mentioned in this thread.

Here are the weights:

For those of you that are interested the stock ACR wheel weights are:
front 26.0 lbs.
rear 27.8 lbs.
My RS 100 HRE's weigh:
front 24.2lbs
rear 25.6
I have a set of HRE race wheels coming, the RC line. Fronts are 22.8 and rears are 23.9.

True they are heavy. But they are strong as hell to resist the 2000 pounds of downforce the ACR-E can generate. They are also, as you say, good looking. SRT was cracking other wheels on track so they went with beefier ACR wheels for production. Also, how many of us will really notice a few extra pounds of the rotating mass. Unless of course you are Arizona.

I lost 80 lbs just from going from stock ACR wheels/Kuhmo's to Forgelines/Slicks. Imagine the lap times Winkler would have got if not saddled with those boat anchor wheels and tires. They were killing braking distances, acceleration and of course handling.
I didn't weigh how much was the wheels versus the tires, I scaled the whole car before and after but I suspect the Kumho's are heavy as hell too. For the ACR I wouldn't run any other wheel but the Forgeline's or Finspeeds. I've had mine at 160mph on wing setting 2. I doubt anyone ever really hits 2,000 lbs downforce, (177 with wing on max setting)

Except this guy when he goes 225.

^ That's junkie's ACR, if that guy had lighter wheels it wouldnt make a difference since the car is making north of 1800rwhp.

Its probably at over 2000rwhp now. LOL

Maybe, but I was warned by SRT's Vehicle Dynamic engineer to keep checking my SWIIs for cracks. I run the SWIIs a lot on my ACR because I have the steel TA brake setup instead of the CCBs. I don't think SRT would have gone with such a heavy wheel if they didn't think they needed the added strength. After all they had lighter wheel designs available.

Keep in mind that every single decision made during design of a car is rooted in money. What you get is the cheapest possible thing that hits the design target of the manufacturer. If you're willing to spend the money the factory wouldn't, you can have "better" parts.

lmao! Have you seen the video of that? It's out there somewhere, the gopro is right on the strakes and you see them grind down instantly. That wing is on #1 setting too, imagine if it was set on #5.

Yeah, I trust Forgeline for sure, but anything can happen. You keep your wing set at #1?

Usually my wing is set to #1. Sometimes I might go to 2 but rarely.

If I'm tracking my car I would 100% ditch the heavy wheels, like Bryan says, these cars where built with some cost in mind. The forgelines are a lot lighter, icing on the cake is they are strong wheels. I dont really know how much stronger, but maybe Tony @Nine Ball can answer that.
Right now im still deciding on two piece rotors or a track set of forgelines.

Yes, the ACR wheels are heavy but I bought an extra set for like $2500. Compared to $8000 or more for aftermarket wheels I can live with the added wheel weight. Heck I've lost 25 pounds myself so I've made up for some of it. I do have two sets of SWIIs as well since I can run 18s on the front of my ACR because of steel brakes.

I thought I'd chime in here. I've been working with FCA over the past couple months to get the sidewinder II's re-manufactured...and I've been persistent. As some may be aware, these have been on back order since 2018. Here is the response I just got a few minutes ago from my FCA contact.... "a new supplier has been selected for the order and our corporate resources are working to get orders filled from supplier to provide an ETA to the dealership. I will continue to provide an update as they come." I'll keep you guys up to date as I get notifications from FCA.

I hope the supplier is up to snuff. Would be bad ass if the supplier is forgeline. Lol

Tell them to powdercoat the wheels instead of painting them. The paint does not hold up on the track and they should also do the inner barrels.

They won't deviate from factory specs. At this point, I'll be happy to get a clean casting...right now you're screwed if you pothole a wheel...that's real easy in New England.

Look at that squat! Seems like there's hardly any contact on the front drivers wheel.
