Alignment issue?

[Coyote 2121]

Hey guys,
I just noticed that my passenger side rear tire sits more forward in the wheel well, while the driver's side is perfectly centered?
Not the best photo, but I actually noticed it from this picture on the showroom floor.
I haven't had a chance to measure it yet, but I can see that it's off.
Anyone else have this issue?
If so what fixed it?

I would imagine it is the “tolerance” in the bushings of the irs. I could be wrong but seems this as the likely culprit.

Hey, thanks for your reply.
I'm wondering if the BMR cradle lockout kit would address this? I know it centers the IRS left to right, does it center it front to back as well?
I had planned to add it later down the road anyway.

My front passenger front wheel is closer to the rear of the wheel well than the driver side by about 1/2” - 3/4”. I’ve always been curious about why that is

Yeah, that's weird too. Have you had it aligned since you've had it?
Does it track straight or pull to one side or the other?
Mine appears to be going straight down the road.
Never had it aligned as it's new to me with only 3400 miles on it.
Are your tires wearing evenly?

I am no Sure on the BMR products. But a quick read on the description from their sight says:

“(fore/aft, lateral, and vertical) is nearly eliminated.”

On my Mach1 (it has the stiffer irs bushings) I put the Steeda IRS alignment sleeves and metal bushing reinforcements as well as the IRS subframe connectors.

all in all I believe the BMR kit you are referring to is based on the same concept as what I did.

Also FWIW my car had 300 miles on it when I aligned it and it was off from the factory, within the broad range that the factory states is good but off for my liking.

I only have 4700km on my 2020 PP2... it tracks well, can't comment on the tire wear, as it's just broken in. I'm planning to lower the car 3/4". At that time it will get an alignment and camber adjustments... perhaps that will fit it?

I bet so.
If it does please check back and let me know how it went.
Thanks for your response.

Interesting.
Can you tell any improvement from the Steeda parts and/or your alignment over how it felt before?
Also, I'm assuming they do a 4 wheel alignment?
Did you use the dealer or another alignment shop?
Good to hear on the BMR part. Sounds like it centers/controls all movement in every direction.
But this is my first IRS car, so quite a learning curve.

Big difference! I aligned it at work to Steeda “street car” specifications

My 2020 Grabber Lime is the same way. I got the Steeda dowels and I think they helped? Maybe? But it's still .25-.5" difference in how each sits.

What does your front look like? I'm convinced something might not be aligned up front from the factory, making these measurements appear off even when the IRS is centered.

You can jack up your car and then remove one at a time the four blue cradle bolts. Then position yourself dead on to the hole and see if the thread insert is offset. Start with the two passenger side bolts.

I recommend the cradle alignment sleeves from Steeda or BMR. Combine with a lockout system to do both in the same session.

I also run aluminum sleeves to take up the large gap in the rear pair of diff bushings.

DAYUM!
Somehow I missed your response and pics.
Yours is way worse than mine!
Mine is about half that bad, but still needs fixing.
Did you ever get yours resolved?
I just ordered the BMR cradle lock out and the Steeda inserts.
Then alignment.
I'll check back and report my results.

Where do I find the Steeda street car specs?
I looked all over Steeda website and didn't see anything about it?
Thanks

Yeah it's pretty bad. I think it might be a mix of the front and rear being misaligned. Last time I looked under the car it looked like my front subframe is fully shifted to the passenger's side, with the outermost points touching the frame rail: https://www.mustang6g.com/forums/threads/front-drivers-side-tire-too-far-forward.153871/post-3552260

I only have the Steeda sleeves installed. Here is what my rear wheels look like now:

So my options as I see them are:

- Get a bushing support kit from either BMR or Steeda and see if that removes any uncertainty in the subframe being centered (see here for what I'm talking about.)

- Ask a body or alignment shop to center the front subframe.

I honestly don't know which option to try first. One worry I have is I center the front first, but the rear is actually off and because the vehicle is still off balance, the front is pushed to the side again.
