RacingLine Stage 3 Front Big Brake Kit VWR650000 - VAG MQB 6-Piston 355/380 mm

All the power in the world is useless if the stock brakes can't keep up. The RacingLine Stage 3 front big brake kit delivers sports-car braking: Forged Monoblock 6-piston calipers and 2-piece floating 355 or 380 mm rotors, for bite, endurance and fade resistance well above stock, plus a look that fills the wheel arch.

Motorsport-derived construction

Each caliper is machined from a single forged billet on a 5-axis CNC. The 2-piece floating cast carbon rotors offer far higher thermal capacity and friction coefficient than a standard steel rotor. The assembly is stiffer and lighter than the stock calipers, which reduces unsprung mass and improves pedal feel. The kit ships complete and ready to install (bolt-on), with braided aviation hoses and street pads.

Frequently asked questions

What is the minimum wheel size required?

Minimum 18-inch wheel for the 355 mm rotor, 19-inch for the 380 mm. RacingLine hub adapters are recommended with the stock wheels.

Is it for track use only or can it be used on the street?

This kit is perfectly suitable for fast road use and handles occasional track days. For very intensive track use, look to the top tier of the range. Caution: fitting on an RS3 2.5 TFSI or TTRS requires spacers to center the rotor, otherwise the caliper and rotor may be damaged. Check with your dealer.

Is the installation reversible?

Yes, it is a bolt-on kit that mounts on the factory fixings. RacingLine hub adapters are recommended with the stock wheels.

Compatibility

VAG MQB vehicles: VW Golf 7 and 7.5 (including R), Audi A3/S3/RS3 8V, TT and TTRS 8S, SEAT and Cupra Leon III, Skoda Octavia and Superb. The exact part number depends on wheel size and brake equipment.

Is the Stage 3 street legal?

This is a performance/track-oriented kit; use on public roads remains possible but depends on local regulations. Check compliance before road use.

Do the rotors and pads need bedding in?

Yes, progressive bedding-in is essential to transfer an even pad layer onto the rotor and ensure optimal, lasting braking.
