My Ride: Audi A5 3.2/6MT
Smile UUC/ Wilwood Brakes installed

After my front right caliper gave me fits for the last 3 months, I decided to move forward with a performance brake kit. I ordered the 4 piston Wilwood calipers, with 325mm (12.8") BMW Motorsport floating rotors (drilled), and SS lines. The few people I know with this kit had glowing things to say about it, so I decided to give it a whirl!

Sure, there are "Bigger" brake kits out there, and it was tempting when looking at Brembo's 380mm (14.9") brake kit. Even kits with 13.5" rotors. But I need versatility, as well as performance and value. It would have been challenging to impossible to use winter 17" wheels, with 13.5-15" rotors! Not all of us live in Texas, Florida or California, lol.


The install process, from the mouth of my mechanic, was pretty straight forward. Aside from finding out I somehow incurred a small crack on one of my Hartge wheels (fixed), and sourcing 6.5mm spacers, all went well. The brake feel is surprisingly OEM. I was anticipating a firm pedal feel, with a "grabby" braking nature. However, brake modulation was very easy and predicatable with no fuss!

I chose matte black finish on the calipers for a more "stealth" look. I know it sort of belies the "other" purpose in getting a BBK (for show, as well as stop). But, I felt Red was too showy for my tastes on a lightly modified car. That and I would've needed the rear BBK, or had the OEM rear calipers painted to match. If I change the color in the future, it'll be silver.

So, stuck caliper issue from OEM brakes = gone. UUC was extremely classy throughout the process, from giving shipping correspondence to overnighting a stainles steel brake line that was defective. I'm abiding by the break-in period, and hope to have more to report later.

Thanks for reading, and have a safe holiday season! Drive safely!

Similar thoughts but i experienced pedal feel that was noticably firmer than OEM. Maybe it was my the 65k miles I had on the original pads/rotors.

For others, here's a tip. Don't order the floating rotor option. Just get the slotted option and then buy the OEM M3 Euro Floating rotors. Same thing as the slotted rotors. So basically you get the slotted rotors + drilled floating rotors for the same price as the kit w/just floating rotors.

Congrats! Welcome to the club

I had fun installing mine! You missed out!!

I am running the 6 piston kit with slotted rotors in the front and I really like it. Much better bite in the wet/snow.

They look sweet! I have just ordered mine and am awaiting delivery and installation. I personally prefer the look of the Wilwood logo and love UUC's products; they are one of the few companies who have consitently spent time and effort to ensure their products were quality and described well.

I simply cannot wait to get mine installed.

I believe the price difference on the 6 piston/4 wheel kit is about $800 between the slotted and the drilled.

I think UUC zinc coats the drilled rotors (the slotted are zinc coated) so you will miss out on that if you buy the OEM M3 euro rotors.

I'm pretty sure you can use any non-ZCP OEM M3 rotor. Blanks or drilled. Another great feature about this BBK!

But pad options are a PIA. Most of them will come with a bolt hole at the top of the pad. You have to grind out a notch to fit under the bridge. At least that's what you need to do if you get the Performance Friction pads.

Thanks, man.

I wish I had the time to install mine. The instructions didn't look bad at all. I salivated over the 6-piston, but couldn't justify it with only 204hp on my car, lol. BUT, I'm sure it still looks good!

Be prepared to go outside, and stare at them for no true reason, lol.

Funny thing behind the "wilwood" logo is that I actually ordered it with the UUC logo. But, my order was fudged and they came with "Wilwood." No complaints from me, as I actually had some remorse after ordering and kinda wanted the wilwood logo anyway. Things happen for a reason!

My friend Alec (HiItsmeAlec) ordered his nearly 2 years ago with "Wilwood," and got "UUC." But, we were both satisfied with the look, lol.

Enough. lol!

Check out UUC's website to get an idea of pricing, options and fitment.




Bigjae, thanks for posting some useful info on the rotors. I'll have to keep that in mind when I upgrade the rears, and replace rotors in the front years down the road!

They have a budget minded wilwood kit and a more performance oriented kit from alcon.

Looks great. Hopefully when my brakes need to be replacing I can go with this kit.
