I was led to believe that all
Mk4 Ibiza Cupras came with Sach's suspension as standard, I have clambered under my car and it certainly has Sach shocks, I dunno about the Eibach bit, I had the Sachs/Eibach handling package on my Leon Cupra and although you knew it was on, didn't look far different from the standard set-up. Enlighten me.
