Red Q3 Calipers: Choose the Product Type First
Key takeaways: identify the product first
A single search phrase can mix cosmetic covers, stock-style red replacement calipers and complete brake kits. They are not interchangeable purchases.
| Buyer option | What it covers | What this page supplies |
|---|---|---|
| Cosmetic caliper cover | An appearance accessory outside this product record | Not included |
| Stock-style red replacement pair | A separate replacement purchase outside this product record | Not included |
| GT6 six-piston front kit | Two calipers plus the listed rotors, brackets, hubs, pads and hoses | This product record |
This page is about the complete GT6 front-axle kit, not a cover or a stock-style replacement pair.
If the buyer needs a replacement for a damaged stock caliper or a purely visual cover, this product is the wrong purchase and a different product record should be used.
The GT6 Front Kit in Plain Terms
The Audi Q3 GT6 front brake caliper kit is a complete front-axle set with the red six-piston GT6 hardware named in the supplied record.
Recorded hardware
The caliper is GT6 with six pistons, supplied in red for the Audi Q3 front axle.
It is sold as one complete front-axle kit, with the component quantities listed below.
Not added here
Piston count is a hardware description, not proof of stopping distance, fade resistance or lap time.
We keep those performance claims out because no product-specific test report was supplied.
The Vehicle and Wheel File Before the Quote
The first quote file starts with a masked VIN and model year, followed by engine and brake option codes.
Public Q3 wheel tables list a 5 x 112 PCD and a center bore of 57.0–57.1 mm, but the custom hat still needs a drawing.
| Control field | What is known now | Required from buyer |
|---|---|---|
| Vehicle identity | Audi Q3, 2011–2024 request window | Masked VIN and model year |
| Engine and brakes | The exact build remains open | Engine code and brake option codes |
| Original front axle | The original setup must be checked | Caliper photograph and current rotor dimensions |
| Factory wheel | A vehicle-specific review is required | Diameter, width and offset |
| Aftermarket wheel | Diameter alone is insufficient | ET, J, spoke photograph and inner-barrel photograph |
| Rotor interface | Public Q3 reference: 5 x 112 PCD and 57.0–57.1 mm center bore | Factory hat drawing and vehicle-record confirmation |
| Rim clearance | Clearance review note | Measured rotor-edge-to-rim gap with the intended wheel |
Four Rotor Rows, Four Clearance Decisions
The wheel and rotor row must be chosen together; rim diameter alone does not approve a build.
A wheel-led rotor choice still needs spoke, barrel, ET/J and measured rotor-edge clearance.
Geometry matters.
| Wheel size | Rotor options | Check on the actual car |
|---|---|---|
| 18 inch | 345 mm or 355 mm | Spoke, barrel, ET/J, disc position and measured gap |
| 19 inch | 362 mm or 380 mm | The same checks with the final wheel and tyre |
| 20 inch | 380/405 mm | Caliper-to-spoke clearance and intended rotor thickness |
| 21 inch | 405 mm | Barrel contour, spoke path and measured rim gap |
Clearance rule
The 6.5 mm value is a clearance rule from the supplied record. If the measured gap is below it, a spacer may be required; if clearance remains short, the wheel cannot be fitted.
Red Finish and Material Choices: What Changes the Build
Changing the finish can change the look and quotation, but it does not create a new fitment.
Appearance and caliper material
- Red is the supplied caliper finish; other caliper colours and a custom logo are available.
- The standard caliper is cast aluminium; forged aluminium or titanium is available on request.
- Bracket and hub choices are listed as 6061, 7075 or 8085 aluminium; the 8085 grade is not yet documented.
Rotors and friction material
- The seller describes the rotor as forged high-carbon iron; alloy cast iron and carbon-ceramic are listed alternatives.
- No rotor forging record or test report was supplied, so that wording remains qualified.
- Ceramic pads are standard; metallic, semi-metallic, carbon-ceramic and carbon-carbon are available options.
A colour choice and a material upgrade are separate decisions from the caliper or piston count.
Inside the Front Axle Box
A single caliper is not this product; one set contains the complete front-axle group listed below.
| Component | Quantity | Interface still to check |
|---|---|---|
| GT6 caliper | 2 calipers | Casting identity, pad profile and spoke clearance |
| Q3 adapter bracket | 2 brackets | Vehicle-generation upright pattern and bracket geometry |
| Brake rotor | 2 rotors | Selected diameter, thickness, center bore, PCD and hat height |
| Brake pad set | 1 brake pad set | Pad shape and selected friction material |
| Braided brake hose | 2 hoses (braided) | Inlet fitting and routing through the full steering range |
| Aluminium hub | 2 hubs (aluminium) | Hat height, hub-face fit and rotor fastening |
Confirm before order is a fitment requirement: check the interface first. We won’t call it a no-modification fit without a Q3 drawing or measured record.
The export reference is 45 x 45 x 45 cm at about 45 kg measured gross weight.
What Changes the Written Quote
No price is published, so the written quote follows the selected configuration and delivery file.
Pricing remains open.
Rotor choice
The wheel, diameter and final thickness determine which rotor build is quoted.
Materials
Caliper, bracket and hub material choices can change the component specification.
Finish
Colour and logo requests change appearance; fitment still follows the vehicle file.
Order scope
Quantity and destination belong in the quotation because no price or currency is supplied here.
Owner, Workshop or Reseller: What to Send First
Q3 owner
Q3 owners should start with the intended wheel and a measured clearance, not with a colour choice.
Tuning or repair shop
A workshop should keep one VIN-based build file for each customer car.
Parts reseller
A reseller should quote the complete front-axle set only after the vehicle file is checked.
Supplier or installer
Provide the missing drawings, interfaces and measurements that would move this draft into review.
- MOQ: 1 set.
- Production: 3–7 business days after the approved vehicle file and deposit are received.
- Delivery: about 20–35 business days.
- Payment: production starts after the 30% deposit is received; balance and route follow the quotation.
- Warranty: 5 years against manufacturing or quality defects only; wear, incorrect installation and unauthorised changes are outside that scope.
- Availability: Made to order.
Q3 GT6 Questions Still Open
Does this page prove that every 2011–2024 Q3 will fit?
No. The year range is the seller’s product window. The VIN, engine, brake option codes, wheel and measured clearance are still required before a vehicle-specific fitment decision.
Will the largest listed rotor automatically clear any matching wheel?
No. Spoke shape, inner-barrel shape, ET/J, rotor thickness and the measured rotor-edge gap still need review.
Can I buy only the calipers from this listing?
The supplied record is a complete front-axle kit with two calipers, two brackets, two rotors, one pad set, two hoses and two hubs. A caliper-only option is not stated.
Is rotor thickness known before I request a quote?
No. The record lists diameters but leaves thickness open for each selected wheel-and-rotor row.
Why is there no fixed price on the page?
No price or currency was supplied. The written quote must follow the confirmed vehicle, selected configuration, quantity and destination.
What evidence would support an independent fitment approval?
A masked VIN, vehicle generation, brake option data, wheel evidence, measured clearance, rotor thickness and a bracket/hub drawing are needed before an independent reviewer can decide.
Real Images, Public Sources and the Next Step
Audi’s production release records series production from 2011 and the second generation from 2018. Audi’s new-Q3 release separates the 2025 third generation. Neither source proves GT6 bracket or wheel clearance. This page was reviewed by SteedLuxParts’ product desk on 2026-10-24; independent fitment review is pending.
