New wheels soon 19x10.5, need help with offset/spacers

[Mr_McShane]

Hey all, first off thanks for the add! Long time lurker here.

I have a 2019 Bullitt currently on project 6GR seven wheels, and I’m looking to get a set of Gramlight 57CRs soon since I found a potential deal. Looking at 19x10.5 +25 and to ideally run 285/35/19s (or 295 if that would fit better) squared so I can rotate my tires. Currently staggered with 305 rear and 285 fronts.

From what I’ve found, the +25 should work on the front with 285s, but for the rear am I going to need a spacer? If so, what size would be ideal for the 285s? No plans to lower the car for now, so that’s not a concern, car is stock otherwise.

thanks in advance!

Well, my phone decided to add more pictures than intended, and i can't seem to see how to delete those...so enjoy the pics of my most recent knife purchase as well

From that first picture I thought "Is that a shift knob made to look like a knife? "


I remember the Gramlight name from my time reading Sport Compact Car.
I looked up Gramlight 57CR, and confirmed those are some good-looking wheels.

The Mustang GT-PP2 came with 19x10.5 in the front and an "ET24" offset, the tires stick out from the fenders, and nobody likes that about their PP2.

I'm rusty on this stuff, but I'm looking at my notes and I think "ET24" means the face where the wheel touches the hub is offset 24mm outboard from the center plane of the rims, and it's really just 1mm different from what you're talking about.
If that is true, then you need a look for a bigger number than "+25", or accept that your wheels will stick out in the front.

The have a square setup and be able to rotate tires - at least with 19x11s - I think people tend to get ET52 offset and use 25mm spacers in the front. Then, they can get the top of their (305mm) tire under the fender if they have enough negative camber.

Since the offset dimension is measured from the center plane of the rim. Between a 10.5" and 11" wheel, the center plane makes a difference of 6.35mm.

...So for your 10.5" rim width, you might need an ET45 offset (and still 25mm spacers for the front).

Edit: Unfortunately (at least according to Fitment Industries) 19x10.5 with ET45 is not an option.

The front likely would be fine (depending on your camber), but your rear will poke out significantly (by about 16mm). Nothing that you can do with a spacer to help that. you'll have to run pretty aggressive rear camber to try to get them to tuck in.

You'd rather have a wheel which is more conservative offset and fits the rear better, then use a spacer to get the front fit correct.

10.5 +25 is somewhat aggressive. No need for spacers since that would poke out your wheels even more. I would say the front is doable with camber around 2.0 degrees. The back will definitely poke unless you want too add a lot of camber back there.

I personally run 19x10.5 +35. I personally would not go more aggressive then this for the rear.
