Audi Q3 8U V-Maxx Big Brake Kit 355 mm 6-piston

This big brake kit Q3 8U 355 mm from V-Maxx is the performance brake kit for the first-generation Audi Q3, with 355 mm two-piece brake discs and 6-piston calipers made of forged aluminium for the front axle. The kit fits all Q3 8U versions from 66 to 195 kW with a steel knuckle.

An SUV like the Q3 has to bring a lot of mass to a standstill with every stop. Under repeated hard braking, such as in the mountains or at a track day, the temperatures in the brakes therefore rise quickly. This V-Maxx kit dissipates that heat quickly via the aluminium caliper, bracket and bell, and the discs have directional cooling channels. That way, the braking power stays consistent.

V-Maxx Autosport is a Dutch manufacturer and gives a 2-year warranty on the kit. Thanks to the TÜV certificate according to §19.3, the kit is approved for use on public roads.

Fitting and delivery

Fit the kit according to the V-Maxx fitting instructions supplied, using the tightening torques from those instructions. The kit only fits cars with original steering knuckles, on the Q3 8U the steel knuckle with Ø55 mm clamp. For cleaning, use a mild soap, as wheel cleaner attacks the aluminium. For heavy track use, V-Maxx recommends removing the dust seals from the calipers.

Available as an option: V-Maxx Steelflex steel braided brake hoses for the front axle (620 mm, set of 2) with PTFE inner hose and TÜV approval, Ferodo brake fluid (500 ml) and a V-Maxx wear indicator set. Delivery time: 4 to 7 days.

The heavier the car, the more heat is released with every stop: this V-Maxx kit with 355 mm discs and 6-piston calipers gives the Q3 8U the capacity to get rid of that heat.

Why choose this big brake kit Q3 8U 355 mm?

This kit gives the Q3 8U a braking system that matches the weight and power of the car. The 6-piston calipers and 355 mm discs give plenty of braking torque, while the aluminium parts make sure the kit cools down quickly. The kit already fits behind 18 inch wheels; for 19 inch wheels, there is the 365 mm kit. You get everything in one package: sport brake pads, adapters, TÜV approval and a 2-year warranty.

Frequently asked questions

Both kits have forged 6-piston calipers and the same application. This 355 mm kit (20 AU355 03) fits wheels from 18 inch; the 365 mm kit (20 AU365 03) requires at least 19 inch and gives more braking torque thanks to the larger disc.

Can I use the big brake kit Q3 8U 355 mm on the road?

Yes. The big brake kit Q3 8U 355 mm has a TÜV certificate according to §19.3. The kit also remains approved with an officially approved power upgrade, because the kW limits refer to the original output.
