depends on personal choice. I don't like bling so silver is my choice. Also, I'd go with the Foliatec 2 part paint as seems the most robust unless powder coating.

 

Puce.

You need to decide what it is you are really trying to accomplish. Is it all about the rust or are you looking to introduce an accent color to your vehicle.

Your rims have a lot of spokes that are going to obscure the view of the calipers regardless of the color your chose. Silver will show the least as it will almost blend with your rim color. Bronze/gold will provide a subtle hint of color and blue would stand out the most though I'd personally not use the M-color with non-M calipers.

Are you planning on replacing the stock calipers with larger ones or just using what you have? The stock calipers aren't that big so painting them a loud/bright color would only draw attention to the fact you have the smaller stock calipers.

If you're just trying to just get rid of the rust and not worried about introducing an accent color then I'd recommend just painting them silver or black. Whatever you decided, good luck with your project

 

if you have just the stock calipers, they’re really not very sexy.
just paint them gloss black.

 

Silver. Keep it simple.

 

Stock silver or gloss black. Leave the lairy colours to the modified Japanese car kids.

 

Mine are yellow.... at the wife's request. Lol

 

If you have stock brakes, there is nothing to showoff. I paint my stock brakes black otherwise you're a poser.

 

For stock brakes I always go silver. From the factory they were plated with a silver colored anti-corrosion coating so I'm mainly going for that look and to match the silver on the coated rotors. The caliper paint below is eastwood 2k silver and I put on a handful of coats to build up thickness and prevent rust.

 

For a stock E46, I like the clean look of silver wheels and all black background.

 

Alright guys I made the decision until the time I upgrade to 330i brakes I will keep mines silver since they are small and not aesthetic looking. Thanks for the great tips I’ll drop a picture here when it’s done!🫶

 

well you could split the difference and go with a golden Cad plating. it’s kinda like a silver-gold color. some brakes calipers come stock with it.

as for sexy brake calipers, BMW really was late in the game compared to others. even the CSL (BMW’s flagship E46) still only got black powder coated single piston calipers.
