I have a 2015 Charger RT. I'm planning to lower it for my next mod. I plan to lower on the Eibach Sportline kit (springs & dampers). I also want to upgrade to a hellcat replica wheel with larger tires. (probably 9.5 wide/275/40/20 tires). Has anyone actually done this with these parts and had no issues? No rubbing or fitment issues. I've read a lot over the past year about this and checked forums, articles, youtube videos. My next step is to talk with a suspension specialist at a MOPAR shop to get another opinion. I would like to hear from anyone that has the same car and has done this. I am well aware of the pros and cons of upgrading to these parts and what it can do. I am looking for firsthand knowledge from someone who has actually done this mod. I'm not asking if you prefer Eibach or another brand. Just what your experience has been in detail and your thoughts. Thank you!

Haven't done it but you will need spacers for 9.5s.

jt2016,

if I plan to go up to 275 size tires will they fit on a 9inch rim? It seems a 9 inch rim there is no rubbing from what I can see. Trying to avoid the spacers if necessary.

I've read about plenty of people lowering and not having any issues with wheel fitment.

FlyersHockey,

with what size rims though? Some guys do the same size all the way around and some stagger. I've seen the stagger where they do 275 up front and 305 or even 315 in the back. Right now I'm just planning on doing 275 all the way around. I've seen rim sizes for 9inch and 9.5 and am not completely sure if I need to go up to a 9.5 or not to fit a 275 tire on it.

I have a scat pack with eibachs. On 9.5s in front and 10.5s rear. Which is way lower than you will be I don’t rub, and I don’t run spacers so I don’t see you having any issues.

Standard RT's have different parts in the front the a scat or srt. The spindles & the knuckles. You will need spacers on the front with 9" & 275's. Rears should fit 275's. But being lowered may change that & spacers may be needed there too.

The 275's will fit almost perfectly on a 9" rim.

Punisher69,

with a slight bulge right? From what I've read from people doing 275 on a 9 inch rim is that they have a slight bulge but that it does not effect performance or safety correct? When I say slight I mean within acceptable standards still.

Here's what a 275 looks like on a 9" rim....my fronts are 275/40/20 on 20x9" wheels.

There is no sacrifice in performance or handling. There are quite literally hundreds of people running 275's on 9" wheels.

Awesome! Looks good and seeing the pics help even more. I feel better about settling for 9's instead of having to go 9.5. Mine is a daily driver and I don't think I will go any bigger than that for the street than 275s....at least right now. :)

The problem you'll have is in the front with the steering knuckles. The rims off set is more negative than stock and will be too close to the steering knuckle (touching it actually). I'm running those rims on my r/t with 20mm spacers. These were the 3rd set of spacers I bought because the first 2 were too small in my opinion even though they worked it was still too close for comfort. I have pic posted somewhere on this site showing the knuckle issue. I'll see if I still have it on my phone to share.
As far as the lowering springs, I suggest against it. Honestly I've done several sets on my mustang and wish now that I just stayed stock. The ride is horrible with eibach. One of my favorite things about my charger is the way it rides honestly. Couldn't be better.
