Big Brake Upgrade from another car

[c7scayman]

Has anyone here done brake upgrade with their Mazda 2 by using brake's from other cars? If yes, how did this affect ABS?

I'm looking into getting larger 16" or 17" rims that should fit the Mazda MX-5 Club Brembo brake kit or a Fiesta ST brake kit. I believe those cars have the same 4 x 100 bolt pattern.

Also, will the tire pressure monitoring system still work with larger wheels and tire sizes?

Fiestas are not 4X100.

Tire pressure sensors are in the wheels so if you get new wheels you either have to get the sensors, or deal with the light being on the dash.

ABS should still work just fine.

A lot of the Mazda 2 front suspension is from Focus SVT last gen stuff so maybe there's an avenue for calipers and brackets.

You'd have to get creative with rotors though. Maybe a VW Corrado, red drilled SVT units or you'd have to go with a custom 2 pc hat design.

Bottom line, how much is it worth to you? Stop-Tech will make ANYTHING you're willing to pay for. As of right now, there's no kit out there because there's not much of a "demand" for it. A great set of pads and rotors is all you need for performance; looks is a different story.

Running a rear disk setup that uses the focus svt rear calipers, svt parking brake cables, custom caliper mount bracket, and fiesta rear rotors. No issues with the brakes as the electronic brake force distribution control module in the abs system does a very good job or sorting out the bias. Honestly, the stock brakes on this car are very sufficient for majority of the applications that these cars will ever be used for. Plus I don't see any real merits with getting a bigger brake setup as these cars really don't weigh that much and most likely won't see any continuous braking from speeds north of 120mph

Nice! I bet a bunch of people would be interested in those caliper brackets if you decided to make more.

I'm going to guess that this is the setup that EF9 is talking about:

Also, you say you have Fiesta rear rotors? How does that work, given that the Fiesta has a 4x113 wheel bolt pattern?

I autocross my Mazda2 often. I go through brakes quickly and I am in the same class as the unbeatable Fiesta ST's and Mini Cooper S's, which have double the hp and torque so I thought the best way to catch up is to brake later and harder than my competition.

At my local SCCA track, the Fiesta ST's run 41-44 seconds and the Mini's run 43-46 seconds. My fastest time completely stock was 46.7 seconds, using stock brake pads and rotors, and mismatched used up all season tires on steelies. I will try the low fade ceramic brake pads first before trying larger brakes. And with better tires and lighter wheels I should at least save 3 seconds.

All larger brakes are going to do is add weight, which is counterproductive. The stock components are more than enough to stop you on an autocross course, even with the rear drums. Upgraded pads, fluid, and maybe a set of steel braided lines are all you'll ever need. Beyond that, it comes down to improving the driver.

A matched set of tires should at the very least be on the top of your priority list before you worry about bigger brakes. (2cents)

I imagine a set of re71Rs would probably knock off more like 4-5 seconds compared to mismatched all-seasons. Auto-x really doesn't put much strain on the braking system. On a light car like the 2, pretty much any pad will work, though some of the cheap pads may not have the best pedal feel.
