Product details
A 290 × 20 mm rear rotor for the matching classic Porsche 911 brake setup. It uses vented iron construction with an integral hat. Sold as one rotor.
Fitment that matters
| Porsche application | Years | Position | Required configuration |
|---|---|---|---|
| Porsche 911 with the matching original brake arrangement | 1969–1983 | Rear | 290 × 20 mm; matching original hub, rotor mounting dimensions and internal parking brake. |
Check the rotor thickness, mounting dimensions and actual brake hardware before ordering. Model year alone does not identify a converted or Turbo brake system.
The 20 mm and 24 mm classic 911 rotors are different parts. Do not choose one by diameter alone. This listing does not establish fitment for Turbo, Turbo-Look or other upgraded brake packages.
