Hi Chaps and Chapet's, I may be returning to the Audi brand after a couple of years away and I'm considering a S4/S5 B8.5 if the right Saloon/Avant or Sportback spec'd car turns up. Looked at a very clean example earlier in the week, so it's there for the taking if I decide that's the way I want to go. Based on this cars spec' I do have a couple of questions (see thread title). When I was last frequenting this forum there didn't appear to be any options for the CREC ECU, which I believe replaced the SIMOS unit in earlier models. This car is a Sept 2015 vehicle, so I assume it will be CREC. If so, what are the tuning options ? Also this car has 'Damper Control' and I seem to recall there was an issue with these when fitting Eibach Springs. If I remember correct there was an additional 'doughnut' somewhere preventing the car lowering on the Eibachs, perhaps just on the rear. If someone could confirm it would be appreciated.
