anyone like racing with ABS?
I've used this car a few times now in wheel to wheel racing, and when I really start to pick up the pace... and go deep in the braking zone, I have problems judging just how deep to go. I'm running an 04 miata with ABS.
There is no feedback. The pedal doesn't kick back; you don't hear any pre-lock-up squeel; the pedal just gets... well: hard. Kind of like brake fade. It's not at all confidence building. Worst, I can't seem to judge how deep I can take it. Anyone like racing with the miata's ABS? If so, what do you feel for with threashold braking? |
Sounds like you need more time on track.
What pads, fluid, rotors are you using? |
Newb thread. you need to confirm a good bleed, then practice.

In the wet, yes I love it.
With a proper "motorsports" tuned ABS, yes, I like racing with it because it will be faster. With a shitty OEM ABS system, and upgraded brakes so the ABS gets a confused, that I don't like so much. |

I mean it stops... I just can't reliably find the edge. In the past I was a racer that really used up the braking zone... now, not so much. Can you explain your "motorsports" tuned ABS? Do you do something like unplug, fine adjust/tune your bias thru prop valves or dual pedals and then plug the abs back in? What braking technique do you use other than just the "plant it hard and pray" technique that I'm currently using? |
IIRC Emilio uses ABS on all his race cars.

At this point I'm not feelin' it... and want to unplug the abs fuse. |

This man speaks the truth.
In the formula car, you can feel every little twitch and hear each wheel for feedback. In the MSM, the brakes are just heavy and there's so little feedback. |
If you haven't added a prop valve to the system, you're not going to be faster than a non-ABS car.

It's 2013, stop using pads from the 80s.
Sav: I'll take you up on the prop valve. I suppose I'm supposed to dial in more front brake bias until I get reasonably even f/r lock and then plug in the ABS? |

I don't know of any such thing for a miata... |

Motorsport 4-channel ABS like the Bosch M4 system is ~$10k IIRC. Since I'm already adding ABS hubs/rings to Theseus for the Racelogic system, I briefly considered adding an M4 ABS system too, until I saw the price tag. $10k buys an awful lot of flatspotted Hoosiers. |
Ah, finally a plausible explanation how the 01+ EBD works.
FWIW the 99/00 systems have a prop valve and don't use ABS for proportioning. Wouldn't the EBD system cause heavy understeer during trail-braking then? |
NB ABS + prop valve = win
Take some practice to get the most out of and nothing I can write here will help. Just go scare yourself until you get the feel for it. 949 Racing SuperMiata - YouTube |

Factory ABS relies on the ABS to do all the proportioning. The caveat here is that you have to actually engage the ABS to get the proportioning working - it will add rear brake after the ABS engages on the front, but that happens way too early.

do you mean the 99/00 abs and replacing the factory prop valve, or taking an 01+ with ebd and adding in a prop valve?
