I've ordered new wheels for my 2024 JCW F57. Sadly, these Advan TC-4 +43 in white are a special order only, and will take at least 8 months before they make them in Japan.

So in the meantime, I want to use spacers to get a similar look.

The Stock Mini is set up with a slightly wider track width in the front, which is typical for a FWD car, and probably done for a very good reason.

I see that a lot of folks use spacers in the back that are 3-5mm wider than the front spacers, to make all 4 wheels have the same fitment.
So the obvious question:
Will this adversely affect handling or steering? (Road driving only.)

Any real-world feedback out there?

 

Your steering feel, feedback, and control will be affected from spacers, but you may not notice unless you go with more than 10mm. I run 18mm spacers in the front to clear my brake set-up. I have noticed an increase in torque steer, and an increase in turning effort.

In the rear, I doubt you'll notice at all.

 

Thanks, Nik.

How much of a problem would you say this is? (For spirited street driving, not track.)
And if it's so noticeable, why haven't you changed back to stock?

I'm planning on changing the stock JCW scrub radius by somewhere between 15mm & 19mm, so this is really important to me.

 

For me, not really a problem, but it is noticeable. Whether its a problem for you or not, will be up to you. I have not changed back to stock because I wanted to run the GP2 brake calipers. Running these calipers requires some compromises. The big compromise is wheel clearance. I also wanted to run late model MX5 Miata wheels. And, while these wheels are light weight and look cool, they do not have much for brake clearance. Thus the 18mm spacers in the front. So, my setup is a compromise for the wheels and brakes I wanted to run.

Is there a reason for your wheel / spacer choice?
