BILSTEIN B12-Pro-Kit Advice

Post by BeardyJon » Wed Mar 13, 2024 2:08 pm

Resurrecting an old thread (as I think it's useful to the discussion) but also to save multiple threads on similar topics.

I'm looking at the Bilstein B12 Kit and understand it's a combo of Eibach Lowering Springs and Bilstein Shocks. I'm noticing on Autodoc there are 2 listings... Bilstein B12 Kit for £965 and an Eibach B12 kit for £682. Are they not the exact same thing? Eibach's website clearly describes the kit as a collab with Bilstein but Bilstein's website doesn't acknowledge Eibach at all.

The Eibach kit says just coil springs in the 'contents' section.

B12 Kit definitely comprises both springs and dampers, the springs are supposedly matched to the dampers for this kit.

I think both kits show as complete, but unless it's a stock photo there's a huge difference in the springs.

A bit more digging and the product photos on Bilstein's online store show Eibach labels on the springs in the B12 kit. So I've got to assume these are the exact same kits just branded differently?
