I’ve recently purchased a used X3 35i and was disappointed in the brake feel and perceived braking performance. My last BMW and Mercedes both had fixed caliper brakes. The existing front pads were fairly low although they passed the state inspection.
I’ve replaced the pads myself with hawk 5.0s and the braking was only modestly improved. It just happened that I didn’t complete the bedding procedure. A few days later after completing the bedding there was a marked improvement in bite while pedal feel improved as well. It’s clearly not as good as bigger fixed caliper brakes on summer tires, but it is pretty good, where before it felt like the pads were glazed. I would guess replacing the LS2 runflats with super sports or similar will just improve it more.
I wonder if we can get a center to center measurement of the spread between the bolts on some easy to obtain fixed calipers to see if there is something that will bolt up to the carrier.
