I used Pentosin Super DOT4 so the DOT5.1 is likely just as good or better. I wouldn’t use anything that isn’t clearly DOT rated

The rotor bolt is for nothing more than holding the rotor in place while the wheel is off. Don't waste your time with new ones unless they're just rusty or stripped.
Bosch ESI6-32N is excellent fluid for anything but track use. It's quite a bit cheaper. I use it in all my cars (except the E82 right now which has Motul RBF600).

Personally, I really like the BMW DOT 4 fluid. Our cars actually call for a Low Viscosity DOT 4 that allows quicker response by the DSC unit so the ABS, traction control and stability control work better, especially in colder temps.
This is another option:

Probably the same as the factory fluid. There is zero need for anything else on a street car.
If this is for a track only car, the only thing that should ever be used is Castrol SRF. |
The BW price on the Ate SL6 is really a good deal. I'd probably go with that for street use if our cars actually benefit from low viscosity fluid.
