I purchased gloss black MRR HR6 rims with Nitto Invos.
Rear - 20x10.5 +25mm 315/35/20 69lbs
Front - 20x9 +20mm 275/40/20 61.5lbs

To get the rears to fit we drilled a new hole in the inner fender well plastic toward the back of the car. We also had to use a heat gun to mold the front of the fender well, where the rib is.

Here are a few pics.

Sexii!

Those tuck up in there great! Nice guess/work! Looks great. How do the 315's bite with the 10.5"? Noticeable?

Could you tell us how much work you had to do on the front rib? Did it just press back with heat? How far did you press? I don't think anyone has done that yet. Both sides left and right side rears? I really need to know, I have the same sizes on the way as you know.

Do u think if u would have went with a 305 nitto , would u have had the same issues ?

 

[IA_Cat]

I have no idea if they bite. I still have a few hundred miles to go before I can test them.
There is metal right behind the rib so you can't do much. We just heated it up, kind of right in the middle of it where the tire could contact it, and used a piece of metal to flatten and smooth it. We had to do both sides. It was really easy.

Lots of guys do 305 and I don't think they have to manipulate anything. With a 315 my speedometer is still correct though.

 

[DGatzby]

I have the 305's on the stock wheels now. 18.5mm offset, you have just more than 5/8" to spare. He took out about 1/4" with the 25mm backset and then some with the 315's. We knew it was tight, but thought success could be found, he did it!

Looks great. Are these hub centric or did you nee hub rings?

 

[IA_Cat]

I had to get hub rings.

Nice IA Cat
As you know I've been looking and speaking of using 10.5 inch rear wheels with 315/35 tires as well.

Really hard to find good wheels that come in those sizes.
The MRR's look good.

Did you weigh the wheels and tires separately or just while on the car?
Seems you gained about 5 lbs each on the rears and dropped 2-3 lbs each up front.
Stock wheel/tire combo (with summer tires) is right about 64.5 lbs
But that's hard to tell how much of that is from the wheels and how much is from the tires.
I'm guessing here, but in the case of the rears it's probably 2-3 lbs from the wheels and another 1-2 from tires.
But the fact you dropped 2-3 lbs up front using the stock size tires and wheels that were only .5 inch skinnier confuses me.
I'd think the Invo's were similar in weight (35 lbs) to the Pirelli PZero's and the 9 inch wide MRR would be similar in weight to the forged 9.5 inch stock wheel, so not sure how 2-3 lbs were lost up front??

The wheels came to me with the tires mounted. The hub centering rings are thin adapters that allow the wheel to fit more snug on the hub. IIRC, the wheels were 73mm and the hub was 71.5mm.

Oh those thin polymer like rings? Oh yes I have seen them on some of the wheels I've gotten. Popped them on before.
Had a brain fart.
Thanks


The MRR's look sick in Black Diamond too.

 

[IA_Cat]

I ordered aluminum rings and used lots of anti-seize.

 

[Driver72]

BTW, IA Cat,

The wheels I'm looking at getting in 20 x 10.5 inch size come in an offset of
20 mm or 25 mm

I'm thinking of going the 25 mm route. However that means they will be further IN towards the suspension by 4 mm (.15 inch) than what your MRR wheels are.
Do you feel that with the heat gun you used and the molding of the plastic wheel well liners you had to do, there would be an additional 4 mm clearance which would still safely be enough?
If so, I'll go that route.

If I have to go the 20 mm offset route, they'll be very similar to yours, but stick out a measly 1 mm more.
Which is no big deal, but I'd prefer to have the additional 4 mm going in, than sticking out.
I want to limit how much debris and shizzle gets thrown up onto the car.

But if with your 10.5 inch wheels and 21 mm offset you think there isn't enough buffer to have them go in another 4 mm (again which is just a gnat's arse more than an 1/8th of an inch) then I guess I have to go the 20 mm offset route.

Thanks brother

 

[IA_Cat]

Driver72,
My rears have a 25mm offset. So that answers question, right?

 

[IA_Cat]

I should add that many of the MRR wheels can be drilled for our bolt pattern even if that is not a listed option. I bought mine from Tiko at Need 4 Speed Motorsports. They took care of the powder coating and all.

Can you post pictures of the wheel well modifications?

...At some point I'd like to try and shoehorn 12's under the rear fenders, and 10.5's up front. I've pretty much modified every car I've ever owned, and never took no for an answer from shops and people that say certain things can't be done to a car. So, I hope that I'm one of the first people (but not the last) to fit a wide wheel on the Charger HC. I would imagine the Hellcats at the 2015 SEMA show will be pretty aggressive looking, with performance upgrades to match. After all, with orders delayed as it is, I probably won't get my 2016 until... 2016. That'll be plenty of time to get some ideas.

 

[DGatzby]

Good luck. Tonight I will be attempting to press the rear liner (front side) just a bit. Expecting the 10.5" wide wheel with an identical offset to the OP next week. As you can see that combo will barely tuck even with the exterior sheet metal. Coldheartid has a great thread showing the clearances and his rear liner (back side) mod which is simple. He also mounted some 315/35's up. We have determined a 10.5" with a 20-25mm backset combo will probably accept a 305/35 with just the rear mod. A 315/35 may or may not need the front side tweak. Any wider and you WILL extend about any size tire outside of the sheet metal. After we mount up I will hope to shoot some suspension pictures and look at the critical clearances for others, to see if more room is available. I think someone may have even put some 10.5" wheels at the 30mm backset, but I will not post for him. There may have been other mods required.

Not even looking to change anything in front.
