1. OEM rotors are not heavy duty enough to cope with track use if you change up your friction material. They will crack out from the drill holes.

2. In respect of the above, if you get BBK, make sure you get slotted rotors.

3. I run a Brembo GT 380 front and 365 rear. Cooked a hardware set using Hawk DT 60. After replacing, Brembo recommended Pagid RS29. They have been really very good.

4. COOLING is vital. If you drive hard and want to get the most from your track sessions, you need this. I have custom backing plates (Cantrell racing)
that direct ducted flow from my duct inlets (on front lip) to the centre of the rotor for centrifugal venting, which is basically A race car setup.

5. Don't buy all the tales about DD use. If you can tolerate at bit of noise and a slight hit on cold brake performance, it's not worth the hassle of constant pad changes.

6. SS lines and high performance fluid a must.

7. Don't remove the backing plates - they are heat shields that protect lines, sensors, ball joints, etc from rotor heat

If you are track-serious, go a BBK. Brembo, Stoptech both good. Also locally, a poster on this forum (can't recall alias) produces Harrop - look quite nice.

Thanks JP,

OEM brakes at the local track hold up fine on 15min sprint sessions, so will be interesting to see the difference after mods. When my car does back-to-back sessions though it does get a bit hot.

Was looking at cooling but the GTS duct kit is too dear. If only someone made an entire aftermarket duct, pipe and back plate kit... Also can't believe this feature didn't come stock! I think cooling alone would probably make the OEM setup miles better.

That's good to know about DD track pads. I heard the hawk hp+ are very very noisy and will chew through rotors when cold. I have to swap wheels, so pads would take an extra hour probably. Could probably leave them in during track season though.

I'm just happy and privileged getting out to a track in an M3 for a bit of fun It's an addiction
