Hi,

As above, looking to fit a set of winters for my 335XD and thinking will a 18" wheels fit over 370mm blue calipers?
Lots of threads about it, but can seem to find a definitive answer.

Thanks

That's because some do... Some don't.. That's why it's not definitive I have 2 sets that do.... You might have to test it to be sure..

Yes oem wheels definitely will, as the 335d comes with 18’s from factory!

No fitment issues whatsoever!

I have 397's which do. Ask your dealer, they will tell you (thats what i did to be sure).

I had the BMW 405m 18" winter wheels which fitted over my 335d with the blue brakes with no issues.

My 18" 400M winter set fit over my blue calipers

No idea sorry mate, not the biggest fan really! In the process of purchasing some 19's so these will be treated as winters!

Brembos with 415 turbines over them.

They won't be 370s though, will they?

They look like my M441's painted black.

My silver ones have served as winters on a 330d and 340i both with 370mm rotors.

Not really surprising, as they aren't designed for the offset on the F3x series of cars.

You might as well comment that headlight bulbs from an E36 / E46 won't fit in a modern F3x.

Looking for a set of 18s for my F30 with 370s. Seen some on eBay but look like they're from an X1 - model 320?

Need to ask the guy to confirm this but anyone know if they'll fit?

[robbiep]

They might fit. But the offset is not correct.

Regularly plenty of wheels on the 'for sale' section here, why not get the right thing that will definitely fit from the word go, rather than wondering ?

Unless the guy you're buying them off has actually had them on an F3x with the big brakes it's unlikely they will actually be able to definitively answer your question.

There is a way to know if the wheels that you want to buy will fit before actually handing over the money. I hope the write-up below helps someone in that situation.

It's the template method that Brembo uses to help potential customers. Essentially you use their method in reverse. You make a cardboard tracing template of your brake calipers mounted on your car. Then you take the template with you and use it to measure against a wheel before you buy the set.

Below is a description of how to do it. I know it's not easy to understand without photos but I'm not able to create photos right now. Maybe sometime when I have one of my wheels off.

To Create Your Own Brake Caliper Template:
1) Remove current wheel from your car.
2) Get a piece of stiff cardboard roughly 8" x 10"
3) place an edge of the cardboard against the surface of the rotor hat surface that contacts the wheel.
4) place one of the perpendicular ends of the cardboard at the exact center point of the rotor hat.
5) I know it's hard to visualize from my description. Right now you should be holding the edge of the cardboard against the rotor hat and in your hands like it was a thin book that you could place a glass of water on top of.
6) Now if if rotate the cardboard around while holding its edge position at the center point of the rotor hat you will go around in a circle until you hit the rotor.
7) Take a pencil and try to draw an outline of how far the caliper sticks out from the surface of the rotor hat. This tracing will form a template showing how far the caliper sticks out and inside of a wheel mounted to it.
The perfect tool to do this would be an inexpensive contour gauge as shown in the attached photo.
8) Cut out the excess of cardboard outside the tracing and you have your completed template.

Take the template with you when you go to purchase the wheels. Turn one of the wheels over. Match up the edge against the mating surface and the end at the center point of the hub. Make sure the template doesn't hit inside the barrel of the wheel and that you have at least 10mm of clearance.

In some cases if just the very front of the caliper template hits the very bottom of the upside down wheel, then spacers may possibly be installed on the hub to be able to use the wheels. But a bunch of other measurements and calculations would have to be done to see if that would look right with tires mounted. TireRack has some tire measurements that may help with that.

If you investigate Brembo Big Brake Kits you will find a Brembo supplied pdf that you print out to use as a paper template.

Instructions below on how to use a Brembo BBK template:
Prepare the template by printing it out. Get a ruler and match it up with the ruler printed on the template. If the two don't match it means that your printer or software is adjusting the image to print a little smaller or bigger. Adjust the image to print at 102%, print and measure. Repeat until actual ruler and printed ruler match. Now your template is to scale.

Take a wheel off the car and flip it upside down. Place the edge of the template at the center point of the wheel. Point the cutout of the caliper down into the wheel. Make sure that it doesn't hit and I think Brembo says to have at least 10mm of space between caliper and inside of the wheel to prevent road debris from wedging in and doing damage.

Note: Brembo Big Brake kits are NOT M Sport or M Performance brakes from BMW. These are kits sold directly by Brembo and are born out of their racing division. For instance the rear BMW MS and MP brakes use a 24mm thick rotor. Brembo BBK rotors are 28mm thick.
