Took fuse out for ABS and did some low speed test runs, under 50 and applied firm brake pressure and car rear wants to jump to right so car like what is stated is rear biased. Want if possible to stay away from proportioning valve so have some questions. Car set up is 305 square slicks, AST 4300 double adjustable shocks, 1200 front, 900 rear springs. Akebono sport brakes. Working now on brake ducts for both front and rear.

Has anyone got a track day pad set up that bias car so it can be ran without ABS? High temp rear low friction, high temp front medium friction?
Was a thinking about putting base brakes on rear, smaller rotor, single piston caliper less braking force, has anyone done this, was it sucessful?

Thanks
Most run the Carbtech's X10 front and X8 rear. A few run X12 front and X10 rear.

I'm somewhat new to tracking in general
I'm running into an issue where I feel like ABS is kicking in waaaaay too early under heavy braking and I can feel the drumming in the wheels. Is that what's considered ICE mode?
Always end up seeing nasty marks on my rotors whenever that happens

My setup is RE-71Rs - XP10 - XP8

Ice Mode is when you have a solid brake pedal and no brakes. Usually happens on entry with a bump to up step the ABS.

I have the same pad combo. On hard braking. It feels like the pads are chewing through the rotors, but they are not. Is that the drumming you're feeling? What rotors are you running?

yeah it feels like somethings "pumping" against the rotors or something. Currently running Z1 2 piece front rotors and z1 perf rear rotors
I end up with pretty nasty marks on my rotors.

I'm thinking that maybe I'm just braking too hard, these carbotechs are like on-off switches unlike the club racers I'm running on the s2k

Drumming feeling is most likely the ABS doing its thing, grip, release, grip, release, over and over very quickly.

yup, that's what I'm thinking, but it's kicking in WAY too early, sometimes when I barely step on it

There is a lot of info in this thread... I read through the first 5 or so pages and I have a question for everyone: Does this only happen around turns, or in complete straights? We write software for ABS modules, and lateral acceleration factors somewhat heavily into the algorithm. If this is an issue when primarily in the turns, I'm curious if disconnecting the yaw sensor would make this go away.

almost all of the HEAVY braking is done on the straight away

Yep heavy braking done while the car is still straight, and trailing off going into the turn apex if braking late. Not sure if doing the yaw switch mod would alleviate this since the ABS sensors are still reading each individual wheel speed, and when you are braking into a turn the outside wheels are turning faster than the inside wheels. I'm sure the makes the algorithm a tad more complicated to write.

Sorry, I meant to say disabling the yaw sensor and the ABS as well.

Anyone got any solves for this? or did all y'all crash??? I saw that ECUTek tune and maybe a vacuum to the breaks may help but I haven't seen anyone say "fixed!"

Just trying to bump an old thread as I plan on tracking the car soon and putting new brake pads on it...

Some get it. And some don't. You have to track it to find out.

ive dealt with ice mode quite a bit... hard braking will lock up the rears 1st... since the fronts are still rolling, ice mode......

the best way (using carbotechs) is to back it off and use more inertial into as many turns as possible.... hammer on throttle until the corner will keep this problem surfacing,,, and you might blow a brake sensor, which dumps you into limp mode until you fix it.
