Car does NOT like to stop after a run

is there a good way to measure braking power? 70->0, 100->0, etc.

That's part of Track Apps.

Joe, an R8 pad would give you more initial bite, have greater fade resistance and offers a wide temperature range. You can run them on stock rotors or our Slotted rotors. This combination can be run on the street without issue. If you want you can also add R8's and rotors to the rear of the car to help balance the braking and also give you more stopping power.

Exactly the sort of thing I'd recommend, and I'd run the R8's or R8-equivalent pads all around. Did, actually.

Carbotech's version of G-loc's R8 pad was enough pad even on smaller rotors than yours for making one 125 to 65 and one 100 to 50 deceleration every 85-ish seconds for 25 minutes at a time. They shouldn't even be breathing hard making one stop from 130 every . . . how many minutes between each run?

Caution - you may get spoiled by the strong initial bite. Spoiled in a good way.


On edit, if your current pads have in fact glazed, scuffing them up will only be a band-aid fix. They'll just do the same thing again and you'll be right back to where you are now.

I put a powerstop z26 kit on mine, made a big difference with the aggressive compound and drilled/slotted rotors IMO

This sounds like a serious brake system issue like loss of brake assist.
Do you notice it occurs at lift throttle from high rpm?
Brake booster or vacuum failure or leak or collapsing vac line.
Please check your vacuum line routing to brake booster.
Check brake booster or just replace with a new one.
Check if your throttle is closing all the way and check any SC bypass valve.
Check throttle plate actuator/motor lag.
If necessary, add a T into lines and put a vac guage inside.
Properly bleed the brakes.

could just be something wrong i don't know about yet. I do notice that I can't use the line lock because there isn't enough pedal pressure. It goes to the floor before that bar for the line lock fills.

Holy crap dude!
If you are not leaking brake fluid and your levels are good, then you might have a crappy master cylinder.
Replace master cylinder and might as well upgrade brake booster to the PP brake booster.
You might also want a back up vacuum source, there are electric back up vacuum pumps that insure vac even if motor explodes: imagine doing 140 between concrete walls with an oil covered windshield and be surprised to find no vac assist on your brakes.
