i just bought a 2004 545i with sports package. are there titanium brake shims out there for this beast?

turboawd

titanium brake shims? what are you talking about?

sickmint79

if i had those, i probably wouldn't have done this

Those are not original parts. 545i brakes are single piston.

that's a pic of my sti. i didn't have OEM shims even, i had crappy shims. too much heat got through and i cooked my brakes on the track. they normally would look like this:



i want to take the 545i out on some bmwcca track days, and would like some titanium shims if they are available

OEM 545i brakes are not for track use. Upgrade them or use added ventilation (intake and hose ducting for front brakes).
You don't want the heat blocked but to be dissipated naturally by improved ventilation. Use race brake fluid with higher boiling point.

i'd only track it 1-3 times a year, for 15/20 minute sessions. doesn't bmw require all (*all*) cars do 10k km on the ring before they go to production? she's chubby but i figure she would be just fine... plan on doing high temp fluid (rbf 600) and nice pads (thinking carbotech xp8) - like the idea of having these on too.

so how exactly do the titanium shims not absorb heat?

Upgrade the breaks...
M5 set or Brembo's...

can go with the R1 disks,new pads, and SS lines and new break fluid.
Ti shims...

sickmint79

they don't, they just retard some of the transfer from pad to pistons/caliper, so the fluid stays cooler. and happy!
