I think you need to add an exhaust. Mazdaspeed 3 exhaust to be exact. I can provide if needed. ;)

I believe that is a dual tip muffler, right? I don't think it would play nice with my single exit bumper. I've thought about an exhaust, but it is nice to have something quiet while cruising around town. The Subaru is straight piped with an external wastegate dump so it is on the other side of the spectrum.

Nice job. That's a lot of good work you've put into the car. Now hurry up and get some good pics. Right thumb!

Nice mods list!............and STI!
Thanks, everyone. I tried to clean the car and get some pictures for post #1.

Only because you are a student, which typically means time and money are limited.
Where did you come from?

Nice build and mods....
Thanks. I come from the middle of the corn fields, part way between the East Coast and California crews.

I've never felt so patronized! lol. I'm just a student for one year. Saved up enough from working to pay for everything, debt-free, etc. as long as I don't go completely nuts. I certainly couldn't justify buy all the things you have on your car, but I can MacGyver and design my own bits to work. :)

Good deal, one-n-done. I only patronize because I admire your dedication and resourcefulness, not to mention the stones needed to push 285 extreme summer tires on the street. With my luck, I would round a blind corner and rear end someone, especially since the Mazda3 likes to come into a corner hotter than the space shuttle entering atmosphere and delicately trail brake all the way past the apex. My car is neutral while coasting or light trail braking, but it can easily scoot the rear end out with enough braking force.

All the bracing AND the jbr comp bar must be bonkers! :Racing 1:

Love the build!
Thanks. The 1.25" competition 0.250"-wall rear sway bar was needed to balance the 28.5 mm solid front sway bar. Not many people stiffen the front sway bar, and I can see why.

Me stones may have gotten me in trouble once or twice lol... Not proud.

Are you getting any one-wheel-peel with the front bar in place? I have not heard of anyone who has been able to use it in a competition setting, even with a big rear sway.

Yes and no.

No, because I don't try to put the power down during >95% of corners.
- Enter corner fast
- Brake late and continue trail braking past the apex
- Wait for it
- Get back on the throttle when the steering wheel is nearly straight again
- Regain speed for the next corner

Yes, because a FWD car wants to light up the inside tire if trying to put power down immediately upon corner exit or throughout the corner. An example on the street is an exchange ramp from one highway to another; if maintaining a constant speed while trying to take the corner as fast as possible, it wants to spin the inside tire, but I'm still going 30+ mph over the suggested speed so it doesn't reeeaaally need to be more capable.

If you can't accept the 'wait for it' step, then you have to soften the front sway bar and use stiffer springs for roll control. I would argue my setup is more comfortable than a car with stiff springs yet it still manages to be fun and capable on the street; mine it not meant to be a track or autox dual-duty car.

I've been playing with mine for a while to see how early I can get ON the power as that's what generates the lowest lap/sector times. Streets of Willow was killing me when I had to wait to hit the throttle. I've been slowly retooling the setup -- stiffer rear springs, more front rake, aero -- to be accept more power 'cause it only gets worse above 200hp.

I installed the Ultra Racing UR-FD3-1961 fender braces today. I haven't driven yet though. This was a worthwhile mod on my Subaru (even though Subaru provided flimsy OEM brackets) so I figured I'd try it on the Mazda3, which required importing the braces from Malaysia. I thought they'd bolt on if I just pulled the fender liner, but that was not the case.

There are no holes for the forward mounting location. I had to pull the fender so I could drill holes.


Drilled 1/4" holes with the bracket mocked up, then tapped M8x1.25 so the bolts were held captive as I tightened the nuts

Yeah, I understand. My biggest gripe on the street is that when I do get back on the power it's 150 lb-ft. :sleeping:

Holy taught!! I like where your mod mind is at. Well done!
Thanks.

I think the front end feels firmer, but my results are a bit confounded (installed upgraded brakes and drove the STI before the afterward test drive). I figure anyone who wants to source the fender braces and install them will already know they want it.

The upgraded brakes feel great when stopping. I was able to have a friend help me flush the brake fluid so I didn't dink around with the caliper paint. While the car now stops like a sports car, it was not without some tradeoffs due to the increased weight and inertia - slightly slower to accelerate, slightly longer distance to coast to a stop, slightly less agile since each corner feels heavier, and a little different feel over bumps.

The better front caliper design also helped eliminate this intermittent brake squeal I had up front. I felt the pad was lightly touching the rotor after releasing the brakes, and I tried everything to stop it: re-bedded the brakes, lubricated the slider pins, added anti-squeal on the back of the pads, and even visited the stealership.

It is now officially cold so I switched over to the winter wheels and tires. I also installed the UltraGauge and aluminum pedal covers. Pictures added to post #2.
