Astra J (2009-2015) B12 Pro-Kit Suspension Kit - Bilstein + Eibach, 46-188779

The Astra J isn’t a race car. Yet. But with the Bilstein B12 Pro-Kit (46-188779), it’s closer - and you’ll feel it before the third corner.

This isn’t ‘OEM replacement’. It’s a purpose-built fast-road kit: monotube Bilstein dampers matched to progressive-rate Eibach springs. Delivers 25-40mm drop, reduced body roll, sharper turn-in, and no jarring compromise on UK B-roads.
