826M Square Set Up

While working out offsets for our new wheels we thought it would be cool to see how a square set up would look like on the car.

It looks good! Only driven the car around the workshop so can't give any feedback on whether this would work in the long run but there seemed to be enough clearance.

This first picture is lowered in the edit to see what that would also look like.

Nice, is it possible to do a square of the 19's?

Does look so much better. Unsure why they come from the factory staggered as they just look under wheeled at the front.

That first shot is money... IIRC, the offsets of the front and rear wheels are the same, is that correct? ET 20 or 25 I think?

They explained it in one vid, because of driving dynamic as more sidewall helps quite a bit in a dynamic drive

I wonder - In what way does the driving dynamic change, going to a square set up?

In general if you go square (usually wider front), you produce more front-end grip and may reduce understeer, creating a bit more neutral handling.

But I can't say how the dynamics may change on a G8X in detail...

By the looks of this it appears that there is plenty of room with that 10.5 in the front, confirming my suspicion all along... possibility of running 11"square.

Track rats rejoice!

What's the square setup entail? Simply spacers add front and rear? If so, which ones were added? 15mm/12mm front/rear?

And please let us know if there's any rubbing with extra passengers, big dips or bumps on the road, or turning from lock to lock...

It's more about the wheels and tires. He's got 20" wheels (rears) all around.

The car looks perfect with 20s on the front, I get the performance benefit of the 19s up front but it really should be an option for customers who are willing to sacrifice a small amount of track performance

I assume they are just one one side of the car IE he moved the rear right wheel to the front left, making the left side have both 20" wheels

You're probably right. But either way, the concept holds up.

20's all round looks so much better.
Staggered diameter setup looks ok on a sports car like a Porsche etc but not on a sedan. Yes I know there was reasons for it, turn in, understeer, blah blah blah but it still looks wrong imo.

With 20" in the front how much performance you think would be sacrificed compared to a staggered setup say with just street use non track? Would a normal driver even notice the difference?
Since i feel BMW nailed the front end traction with this car dont really want to mess with that

The big difference with the F8x platform was that the traction and stability system was programmed for the shorter front tyre. If people changed sizes and made them the same diameter overall the systems limited power quite a bit as they thought the rear was spinning.

I think you'll notice that more than any actual handling difference tbh.

Square set would be ideal for AWD set ups too. A clean tire rotation would maximize tire life as well.
