Thumbs up
for another TF running on Bilsteins.
One of the best £600 I've spent on my 2003 135 so far.
As VX54NEW states the major difference is in the smooth but controlled ride they give, even with the original springs. When I first got my TF I was convinced that it was going to shake itself apart, but now it's totally different with far less crash bang motoring.
If you do decide to go down this path I suggest you deal direct with VHS as they have the Bilsteins available at the best price.
