I am facing an issue with my car, a 2008 Mini Cooper S R56. I have installed a big brake kit with a 350mm disc diameter and 32mm thickness. However, I cannot fit the wheels due to interference with the calipers. To solve this, I added a 15mm spacer. Now, I want to remove the spacer, but I need to find a solution to replace the calipers with a thinner or smaller one as I am lacking 12mm of clearance space.

The reason I need to remove the spacer is that my car is due for registration soon. In my country, using a wheel spacer is strictly prohibited, so I need to take it out.

Is there any solution? I cannot replace the entire front brake system to get the original one as my original set is damaged and rusted and cannot be used.

Can I use the original calipers for a 32mm disc thickness?

 

What country and why cant you use a spacer? You would have to go all back to the stock set up.

 

Some of those European countries have those regulations.

I think you're only options are going to be find a set of wheels that will clear, or go back to stock set up to clear your inspection. I imagine going back to stock brakes will be the quickest and least expensive option. After the inspection, swap back to the big brakes and wheel spacers.

 

Where I am currently living, the process of getting a car inspection is very illogical. My car was manufactured in 2008, so I have to get it inspected every six months. Every time, they come up with all sorts of reasons to reject it, such as the headlights not being bright enough, the wrong type of headlights, not allowing spacers, not allowing larger tires (for example, going from 205/45/r17 to 215/45/r17), not allowing changes to the grill, and not allowing body kits. What's even more amusing is that the people who do the inspection in my country often have less experience than the car owners themselves (in most cases).
