on my next track car, I've planned to use Wilwood 11" BBK front and standard 1.8 rear. I find when I use sport rear, I get too much rear bias (when I run same pads front and rear). make sense ?

just for clarification, on an ABS miata how many channels is the brake system? some cars have 4 channel independent brake system so you would either need to re pipe the system or perhaps use 2 bias control values, one for each rear wheel. on a 2 or three channel system with 2 front one rear, or one front one rear then one bias control would be fine.

perhaps someone with a more in depth knowledge of the ABS system can chime in. I don't have abs

great, well that makes is simple for the abs guy. I think the late NC cars are four channel but I might be wrong on that.

cant wait till my car gets to the point where I need to tweak the brake setup further! so far I hardly use the brakes and have yet to even light up the lowest temp range on the caliper temp strip. Im sure a track with hard braking zones will yield different results but so far, these are the best brakes Ive ever had on a track car and I'm not even running aggressive pads.

For those who are somewhat new, I would not worry about changing masters or rear calipers until you experience issues first hand. with the bbk and medium track pads I think you will be fine on most tracks. that said, I was focusing on other aspects of the car, so i'm sure my brake zones were somewhat lazy compared to the guys turning good times an a equivalent car. still a little paranoid about flat spotting tires after my last car, awful brake lock issues and I was running the "right" parts, user error I guess.

I don't think so. 2-channel systems typically run diagonal corners on different circuits, which requires two hydraulic lines going to the back of the car. The Mazda parts diagram for ABS on a 91 only shows one, still with the junction block near the passenger rear wheel.

My 1.6 car with the Sport master has a front line on the bottom, a front line on the side, a rear line on the side of the master.

My '93 1.6 had a 3-channel ABS system.

I think the +05 abs cars are 4 channel but I could be way off on that.

The NC (2006 and up) has traction and stability control, which require 4 independent channels.

The 2005 is still an NB and has the same single line going to the rear.
