It would appear that the US and Euro eibach Pro kit springs are different. The part numbers are different and US spec springs quoted as dropping the car 5~mm less, US 20-25mm Euro 25-30mm. Are the spring rates any different and does anyone know of where to get US spec springs without having to pay £100+ postage?
Maybe from here: https://eibach.com/de/en/content/eibach-uk
Well you would think wouldn’t you, but they only list the European part numbers. I did ask Eibach if they had different spring rates but did not get a reply.
