Update:
I'm reviving this post as I've been unable to find answers. Perhaps this is part of the secret sauce people use in their setups?
Has anyone had their shocks re-valved for the stiffer rates of the Swift springs. I would expect good gains as the shock must be working very hard to control the heavier springs. Or is there enough adjustment to increase rebound dampening sufficiently? My track time is extremely limited, so I would like to show up with the setup as close as I can get.
Older post from 2021:
I have this suspension on my car, but I'm not able to get the papers needed to get them street-legal ( I live in Europe) because the Swift springs are not TÜF approved. Bilstein recommends reverting to the original springs which will make the kit street legal.
Does anyone know if the shocks are re-valved for the heavier Swift springs?
Here are the part numbers in case it helps.
Part number of the front shocks: VM35252
Part number of the rear shocks: VM35253
