The highly rated (on here) Eibach Street Pro's, which are KW dampers with Eibach springs, are readily available. I got mine from AUTODOC for circa £750.00 including delivery, along with some excellent customer service from them. 👍
Ive been waiting seven months for a set of Bilstein B8s.
They were a birthday gift for a friend, and i ordered them from Demon Tweeks, last November.
I contacted Bilstein direct back in March, and they are have serious issues in obtaining the required steel for manufacture, in their German factory.
Anyone who orders Bilstein shocks that are not currently in stock, may have a very long wait.
Good thing i didn't tell my friend what i had bought for him.
