I was wondering if anyone knows the OEM front brake rotor diameter for a 89 200tq and a 96 A4q. Ned Ritche once told me that switching to A4 rotors was a good upgrade for the 200tq. What would I need? From what I understood, it was just the caliper carier and rotor from an A4. Anyone BTDT? For now though, I mainly want to know the rotor sizes for these two cars. thanks, erik
