UPGRADING SUSPENSION:

[AndersLS]

Hello guys/gals......I am upgrading my suspension to full m-tech.
What is the difference between B4 dampers and B8 dampers (bilstein)

Anybody got a good deal on mtech ARBԚ´s ,...both front and rear?
Are EibachԚ´s just as good...better?

Anders.

M tec fromt arb's are 20mm but the 6 pot convertible ones are 21mm so you would be better with them.
