Opel Astra G Caravan T98 – The versatile station wagon for your conversion project

The Astra G Caravan T98 was built from 1998 to 2004 and is one of the most widely used Opel models of its generation. It combines everyday usability with robust engineering and also offers a solid platform for individual tuning modifications.

As an estate car with plenty of space, clean lines, and a wide range of engine options, it's ideally suited for modifications to the brakes, wheels, and suspension. But this is precisely where it becomes apparent: modern components rarely fit without modifications. The bolt pattern prevents many wheel combinations, newer brake systems require new mounting points, and even the suspension quickly becomes technically complex.

Our TuningadapterWe offer you exactly the solution here – precisely manufactured, TÜV-compliant and available directly from the manufacturer.

Brake adapters – For safety and improved performance

When brakes have to pull along

Even though the Astra G Caravan is well-tuned in its standard configuration, those who drive more sportily, use larger wheels, or actively want to optimize the handling will need a more powerful braking system. OursBrake adapterThey allow you to upgrade to more powerful brake calipers and larger brake discs – e.g. from the Astra GSi, Vectra GTS or even from the Audi/VW segment.

This gives you noticeably better deceleration, more control and a modern braking feel – even at higher speeds or when towing a trailer.
