Spring pad thickness - ??

[5five]

Hi,

I have a 230E and I would like to lower it. So, I bought H&R springs (lower by 30mm).

I am not sure if I have the Bilstein B4 or the Bilstein HD.

I need to buy spring pads but I am not sure what is the correct thickness for my set up.

Thanks for helping

how much lower do you want to go? Once you know that, you can choose shocks to suit.
