While the 1969 917 K was unstable and very difficult to drive, the rear end was completely redesigned for 1970, to finally generate downforce instead of unintended lift. The 1970 car was sorted and ready to take on the competitors. The cars built in 1969 were converted to 1970 specs. The first major victory arrived right in the beginning of the season - the Daytona 24 hour race saw a 917 K 1-2 finish by team John Wyer Engineering.

1970 Ferbuary 1, Daytona 24H winner 917 K-70 (chassis 917-015) #2 Pedro Rodriguez/Leo Kinnunen. The front end of the car has a lot of taping done to it - a usual sight of the car of the hot-blooded Mexican. Second place went to 917 K-70 (917-014) #1 Jo Siffert/Brian Redman and third place to Ferrari 512S #28 Mario Andretti/Arturo Merzario/Jacky Ickx© unknown (please inform us if you know)
1970 April 12, Brands Hatch 1000 km, Porsche 1-2-3-4 victory: 1. 917 K-70 (917-016) #10 Pedro Rodriguez/Leo Kinnunen, 2. 917 K-70 (917-023, the car that would win the Le Mans after 2 months) #11 Vic Elford/Denny Hulme, 3. 917 K-70 (917-020) #12 Richard Attwood/Hans Herrmann, 4. 908/02 K Spyder© unknown (please inform us if you know)

The 917 K-70 of the J. W. Automotive Engineering team + Leo Kinnunen & Pedro Rodriguez proved to be the winning formula. They took already the third major win in the season - after Daytona 24H and Brands Hatch 1000 km, also the Monza 1000 km. Another evolution to the 917 is seen at the Monza 1000 km - the 4.9-litre engine.
