Hey All,

Apparently I drive aggressively (heh) and I have a tendency to warp my Mazda3 2007 hatch front rotors easily.

I was thinking of stepping the front brake set up a notch by running steel braided lines and upgrading to the Mazda Speed 3 rotors for a tad more braking power.

The stock Mazda3 hatch rotors are 10.6" diameter and the Speed 3 rotors are a smidge over 11" (Yes—I'm aware I need the Speed3 caliper and caliper bracket to run the slighly larger Speed3 rotors.)

Here's my question.

The stock Speed3 rims are 18", and I'm running some Motegi aftermarket 17" rims on my 07' hatch. It "looks" like there's going to be enough clearance to upgrade to the stock Speed3 rotors/calipers, but I was wondering if there was anyone else out there who did this upgrade? ..and are you running 16", 17", or 18" rims??

Thanks!

Do you really warp your rotors? See Tech Article: Warped Brake Discs and -Warped- Brake Disc and Other Myths

Thanks for sharing! Very interesting. I'll bed in the new set (due for replacing anyway) and see if it makes a difference.

I have also found that going for a quick fang running some highly metalized sintered, street legal. track day type pads also deglazes the disks and gets rid of the "warping". I keep a set of these pads specifically for this use but run normal pads the rest of the time. These pads are extremely abrasive and if used all the time would soon take the rotor down to its minimum thickness. You would not want to run them all the time. Note this is not on a Mazda 3 but on larger Oz made Ford Falcons and Fairlanes and on a Mitsubishi LC Lancer (same as the Plymouth Arrow in the US).

A quick "fang"? What on earth does that mean? Like, a "zip around the block" or something? Just enough to bite them in?

Sorry; it's a local Western Australian slang and apparently some think obsolete terminology see AUSTRALIAN SLANG | Western Australia | www.wanowandthen.com Though I see the Kiwis use it too https://www.brenontheroad.com/travel...zealand-slang/


I suspect it's an abbreviation of Fangio (the F1 driver of the 1950's ) but in any event go for a spirited race car like drive involving some heavy braking.

And I'm not the only one still using the term. https://www.wheelsmag.com.au/reviews...-review-part-3



So go for a quick fang in it Fangio :-)

Australia did try and indoctrinate you all with such great automotive terms through the Mad Max movies but I guess we failed. See https://www.quora.com/What-does-fang...Fury-Road-mean

Ah, you are from down under, that explains my not knowing it. (Although I'm Brit born, but it must never have made it to the UK either, hah).

I'll try and use it here and see if I can get it going! I like it! heh

But the poms use it already (albeit perhaps only the ones of my ancient generation) e.g. Jaguar XE feature review: a 1351-mile drive to Gibraltar by CAR Magazine Daily grind as well as the occasional country fang.

Mazdaspeed3 brake parts won't fit your 3 unless you swap out the whole shibang: Calipers, rotors, brackets, lines, master cylinder.

The rears are interchangable/the same. A lot of people, when doing the MS3 brake swap, put Mazda5 rears on. The swap right in and are a little bigger.

I did the MazdaSpeed Mod.

They are 12.6 inch rotors. Got the rotors from a online dealer, the calipers from a junk yard, braided brake lines, new lower control arms and Koni shocks.
