Are there any other retrofit options other than F80 M4? The used caliper/rotor kits are selling for ~$1,500-$1,800, so with the price of the knuckles, we’re encroaching on StopTech prices.

Any other OEM Brembo or M Performance kits will work??
I did the math when I was looking at that option, it will most likely cost somewhere around $2100-2300 if you go the F8x retrofit option. The F8x retro is probably the cheapest and most compatible kit you can find.

Sometimes you see the F8x OEM kit for $1000-1200 range but you have to be very lucky or patient. I have seen the calipers only for $600 and that's the lowest I have seen in the US.

No respectable BBK or retrofit options are available for considerably cheaper as far as I know.

IMO ST40 Front+OEM Rear>any retrofit around same price range.
How do you suppose the F8X brake retrofit compares to the StopTech ST40 kit in terms of performance?

Are the StopTech brakes a lot better? Or similar?
