Well, just got an email from the seller in Germany who said they cannot get this anymore. It was a really good price I paid so maybe they realized they sold it too cheap when they went to get it from another vendor. In any case back to square one. I'll now research on here the different setups, H&R sport springs and bilstein sport shocks seem to be the most popular but will check out all combos.

This is still likely a relevant thread for people to weigh in on the sport cup kit which does look really cool.
