Evo sport disc and pad up grade track report
Well Tuesday i had a epic track day with my big heavy E55. last time out i was on stock tires and brakes, and thoughs of you who know they both suck!
After upgrading to the ps2's and evo sport disc and pagid pads, i was really anxious to get out on the track to see the difference. the Ps2's on the st are like night and day compared to the contis but the track is a different beast and yes they worked excellent, to say the least. now to the brakes, After passing lambo's M5's, M3's,gt3's, turbo p's etc etc The brakes worked so good i had to post about them.
They not only stopped the big boat better i was so confident in them i was out braking just about everyone on the track except a few race cars.(now most of this is from the skills i have of running it in deep
) but if you don't have the confidence in your equipement you can't do it. and yes after 5-6 laps in the advanced group They DID NOT FADE! Yes the brakes are hot warning came on every time out, but of course I don't give a F about that warning, i think unless you put air directly on the disc you'll get that every time out.
Now most of you are thinking "were's some pics or better yet video of this epic track day??" ITS COMMING SOON!!

PS2's around the circuit for a day, they are truly fried around the outside edges
The reason your "brakes overheat" light cames up so soon every time is because your tires are not up to it. After overtaking everybody down the straight bits, you are forced to brake late to slow right down before every corner more than necessary or you would have slid right off the track.
If you use R compound tires around the circuit you will cut the brake use by 70%. It is a real shock to a Porsche driver on street tires when you stay on his tail around the apex only to blow him away on exit
Good to see another E55 driver who is prepared to take his car on the circuit track rather then just go drag racing in a straight line.. yaaaawn...zzzzz.

As far as brakes are concerned, I disagree. You need to use brakes far less since you can hold more speed into corners. With street tires you go flat out down the straight only to jump on the brakes before every turn, otherwise you just plow into the paddocks.

With the greater available grip, the r-comps allow for much greater braking forces to be exerted before lockup (or ABS threshold)
Measured on a G-meter, It was the difference between just over 1.0G on street tires, to 1.18 to 1.2 G on r-comps.
For my brakes, it was the difference between 4 sessions before the pads were toast (street tires) and 3 sessions on the r-comps.
Your mileage may vary.

Which leads to higher entry speeds, requiring more braking, etc.....

Sorry, but that does not make sense!
Higher entry speed requires less braking, not more!
If you are going at 140mph on stock Contis and you have to brake to 100mph to enter the turn you need to stomp on the brakes all the way to ABS in the last 200m, or you will hit the tire wall 300m away.
If you are on semi slick R-compounds, which allow you to go through the same turn at 120mph, you just tap the brakes gently and you quickly lose the excess 20mph.
The difference over 12 turns/ lap times 8 laps is huge. After overtaking all 15 cars in the group, my "brakes overheated" light hardly ever comes on and then its in the pits.
Check out this video to see the difference between our "German Taxi" on semi slicks compared to sports cars on street tires

If indeed, it calculates the number of applications times the pressure applied to the brake pedal, you will apply less pressure, less often and the warning light will not come on at the same time as on street tires.

If that is the case, why does the warning message "brakes overheated" come on rather than "brakes over-algorithmed" LOL?

Can we agree that you can brake harder (ultimate g-forces) with r-comps?
Can we agree that harder braking uses pads faster than softer braking?
I don't see the issue?
Perhaps if you wanted to put down identical lap times to those on street tires you would use less brakes, but I use the additional available grip to go faster, brake later (and deeper), and turn shorter lap times.
FWIW, the brake light is mathematical calculation, not some temp sensor output.
As always, your mileage may vary.

I'm not debating whether r-comps make you faster around the track or not - they do.

I guess if I pushed the car to the absolute limit I would end up with no benefit to the brake use.

i thought it was already established here that the brake warning is not a function of temperature, but a mathematical function of brake applications and pressure. you can change them to whatever you want and the warning will come on at the same time..... no?

I always assumed it was brake fluid temperature, which made the use of high boiling point race fluid all the more confusing. The warning light goes off prematurely as the sensors are calibrated for stock fluid only.
