I'm not sure how the css bumper would affect the rotor temp, but I think they have extra airflow for the auxiliary heat exchangers mounted in front of the wheel well. What I do know is that we need more airflow through the main heat exchanger stack and all the airflow there is precious. I'm rethinking siphoning air from there for the brakes and going back to looking at my naca duct design we talked about. There's a lot of air that gets trapped in the wheel well, and there's really no room for fender louvres (I'm going louvre crazy over here, lol), so lowered ride height is pretty helpful there.
I'm really not sure why I'm getting fewer bubbles with booster being higher. They're not totally gone, but I can at least make it through most of the day without the pedal going to the floor.
I had the booster set at 5 stock and offset was 5 as well i think. My understanding is that the booster just provides extra pressure per pedal movement while offset delivers the final pressure. This would mean that a setting of 5 and 8 comes to a difference of 3 to have the booster increase pressure by that arbitrary value until pedal floor. Keep in mind pedal floor is far below end of realistic pedal travel to account for fluid loss, fade, etc. By moving to a value of 1 for booster and 4 for offset you'd have the pressure increase be the same, but just less pressure through the system as a whole. This would result in a longer pedal from a lower floor, but the same overall "feel". Going to 1 and 8 (what I was at before), resulted in a shorter pedal with less upfront pressure and a higher floor. With current setting being 4 and 8 I have more upfront pressure, a slightly lower floor, and a more even pressure throughout. It's definitely something to experiment with as it dramatically changes feel on track, but it's hard to summarize without "feel".
Maybe it's the extra pressure that raises the boiling point of the fluid just enough? Fluids under pressure have greater boiling points after all... Otherwise our radiators would kaboom all the time...
That's a good question on rear bias, and not one I can clearly answer as I'm still running the r8 rears that came with the non pp pad shape accidentally, so my rear rotors are getting less torque than usual. It has not drastically affected my trail braking though. I did go slightly more toe in in rear, and I hate it so I'll be backing out even more toe than before (I might just aim for 0 if it can be achieved, but I think the -2 camber might limit it).
