Replace 18's With 20's?

I can replace the 18 inch wheels on my R/T with 20 inch Heritage wheels from Challenger 2008-2010 - Take Off Auto Parts.com OEM Wheels & Parts at DIY Prices! Buy and $AVE! correct? I peeked into the wheel well and to me it doesnt look like it will clear the upper arm. I am no Tech, what am I missing? Please educate me.

The search function doesnt like things like "20" and"18", couldnt get anything to come up.

Yes, it will fit...they came off the same exact kind of car as yours.

Thats what I thought, it just doesnt look like the suspension piece hanging over the wheel will clear it. I thought maybe the vehicles with the Heritage wheels had a different suspension option. I am not having much luck finding detailed explanations as to what my option codes are. What does a front suspension parts module consist of?

Front Suspension Parts Module

I'd swear I saw something around here that explains things such as these but danged if I can find it now.

They will work, no sweat. I replaced the 18s on my Charger with 20s from an SRT. I had to use 3 mm spacers in the front to keep from rubbing on the control arm at full lock. The wheel shop had the spacers. Have had the Charger for almost 5 years and no issues.

Thanks guys, I was actually looking around for something for my wifes charger, she didnt like those but they kind of caught my eye, always liked the Heritage wheel. I have also been eying up the police steel wheels, they will fit in nicely with the blue/black theme I have going.

Unless I am missing something there is no way 20's are going on this car. There is only about 1 1/2 inches between the nut in the picture and the tire. So what am I missing?

How is it going to fit beneath the arm/link/sub frame, whatever you want to call it? I can barely get my hand between the nut and tire. The 20's look more than an 1 1/2 inches taller. I was at a dealer today and the Tech was telling me they tried to put them on one of their used R/T's and they would not fit, I had actually forgotten about it for the time being until he mentioned it. None of this computes with me because they should fit. Do you have to have the Track Pack to get them on?

All I can tell you is that I had stock 18s and went with the same tire size 20s that come on the R/T and have driven 8k miles so far. The 20s don't have as much sidewall as the 18s I know that.

My car came from the factory with 18" wheels, but 20" wheels were put on at the dealership. No fitment issues.

The tire with the 20" wheels will be approximately the same diameter as the tire on an 18" wheel. The 20" wheel is bigger, but the tire has less sidewall.
