Description

Opel Astra J / Astra J GTC V-Maxx Big Brake Kit 330 mm 4-piston

For the Astra J with PCD 5×115, this big brake kit Astra J is the complete V-Maxx solution for the front axle. The kit consists of 330 mm two-piece brake discs on ultralight aluminium bells and 4-piston calipers made of forged aluminium, and fits the Astra J, the Astra J Sports Tourer and the Astra J GTC.

If you use the Astra J or GTC on the track, you want braking performance that stays stable, even after a series of fast laps. V-Maxx achieves that with aluminium calipers, brackets and bells, which conduct heat about 5 times better than steel, and with discs that have directional cooling channels. The kit comes ready to fit with sport brake pads and adapters, and has a TÜV certificate according to §19.3 for public roads. V-Maxx Autosport is a Dutch manufacturer and gives a 2-year warranty.

Fitting and delivery

Fit the kit using the V-Maxx fitting instructions supplied and observe the tightening torques. The original steering knuckles are a requirement for fitting. Do not use wheel cleaner, as it attacks the aluminium; a mild soap is sufficient. V-Maxx recommends removing the dust seals from the calipers for heavy track use.

The kit can be extended with a different caliper colour (black, blue or yellow at extra cost), V-Maxx Steelflex steel braided brake hoses for the front axle (620 mm with convex-concave adapter set, set of 2, PTFE inner hose, with TÜV approval), Ferodo brake fluid (500 ml), a V-Maxx wear indicator set and an extra set of Ferodo FDSR216 DS Performance brake pads without TÜV approval. Delivery time: 4 to 7 days.

Three body styles, one PCD, one goal: an Astra J that keeps braking consistently on the track.

Why choose this big brake kit Astra J?

The big brake kit Astra J tackles the biggest problem of braking on the track: heat. Because the caliper, bracket and bell are made of aluminium and the discs have directional cooling channels, the kit cools down much faster. As a result, you keep braking consistently, even when you have to brake at full force several times in quick succession. The complete delivery, the TÜV approval and the 2-year warranty from V-Maxx make the kit suitable for both the road and the track.

Frequently asked questions

Does the big brake kit Astra J fit the Astra J OPC?

No. The big brake kit Astra J is intended for the Astra J, Sports Tourer and GTC up to 147 kW with PCD 5×115. The OPC is not included.

Which brake hoses go with this kit?

You can keep using the original rubber brake hoses via the supplied adapters. As an option, V-Maxx supplies 620 mm Steelflex steel braided brake hoses with convex-concave adapter set (set of 2), with TÜV approval.

Is the big brake kit Astra J suitable for a car with more power than standard?

Yes, definitely. An Astra J with more power than standard benefits most from this kit: 330 mm discs and 4-piston calipers give more braking power and much less fade. The kW limits in the application list refer to the original factory output, and with an officially approved power upgrade the TÜV approval remains valid.

Does the kit fit behind my 17 inch wheels?

17 inch is the minimum wheel size. Use the fitment template (WFC) to check whether your wheel fits; a wheel spacer is sometimes required.
