list of brake upgrades for bg

[300BHPZE]

Took me about a year to find them through a board member over there. It's the same swap that DaveOr did in that other thread.

This is my list of supplies...

323F BA V6 spindles...$110 (I got a wicked deal from a UK member so that was mostly shipping)
EBC MX-3 blank Rotors...$100 (incl. shipping)
SS Brake lines...$40 (this is half the cost of the set I bought last year)
94' Subaru Legacy Turbo Wagon calipers...$115 ($45ea + shipping from a wrecker in Calgary)
89' MX-6 caliper brackets...$15
Brake pads...$70
Wheel bearings and seals...$80
MX-3 hubs...$60 (didn't want to have my car off the road while I take them out of the stock spindles)
Proportioning valve and front hard lines ...$30 (ABS delete)
Misc...$30 (paint for calipers and brake fluid and stuff)

TOTAL: ~$650

But with all these parts the whole thing bolts on. Easy peasy.

What about a 929 master on a bg? bolt on? Good upgrade?

The 929 MC has larger bore (1") than the Protege (7/8") so with the same pedal travel more fluid will be pushed through the system. This would be helpful if you were upgrading to a caliper with more piston area than stock. It also may allow you to generate more brake force, but I think it would be marginal. You should try it and report back.

I have talked to another member who has done the swap I'm doing and he's using the stock MX-3GS MC and has not had a problem.

the 929 and Protege use external proportioning valves, right?

[Mazda_Powered]

correct

[mazda1993]

Yeah i will try it, i'm gonna have my 5 lug swap in about a month so when everything is gonna be on the car i'll let you know!

oouuuh GTR spindles?

Another point that no one has really hit on is that, because we know that the Miata rear caliper bracket bolts up to the BG rear spindle, we can infer that the Monster Miata Big Brake kit rear brackets will also bolt right up and allow the use of RX-7, 4 piston calipers and Wilwood vented rotors in the rear. So if guy could get a hold of a pair of those calipers I'm sure you could make your own brackets and spacers easily enough.

Fronts are a bigger challenge because of the position of the mounting points for the stock caliper but with the BA V6 knuckles that shouldn't be a big problem anymore when I can put together enough money to try some stuff out.
