Hello together,
thanks for all the replies!
Just like Dennis stated: For insurance/registration reasons only setups for 15" wheels are an option. At least from the outside it needs to be remotely stock or period correct appearance
As far as I take it the SSBC-kit seems to work OK regarding fit of the adapters, calipers and so on? This would stay a setup with power booster anyhow!
I am also somewhat concerned about is brake balance. Does the SSBC setup overbrake the rear really bad? Is it fixable with a regualtor valve?
Best regards
Florian
