Bought my e89 with Continentals - non RF. Handling and cornering grip - superb ! Epic !
Had to replace the rear tyres due to unrepairable puncture and figured I’d try non RF Falkens. Well - what fun I had for the first 1500 miles. At 80 mph , the car felt I was towing a snaking caravan . The slightest steering correction resulted in over correction . I had to keep both hands on the steering wheel. The car did not feel safe.
On country roads - Entering corners with the slightest of down hill gradient at speeds I was used to with conti’s , resulted in DSC kicking in . Too easily .
After 1500 miles and plenty of burn outs , the Falkens came good. Throwing the car into the corners and getting the car weighted on the back tyres was the way to go. The car drives in a perfect straight line over at 80+ now and I feel safe again and am quite happy with the ride.
If you put Falkens on your car - bare with them - they need about 1500 miles to run/bed in and several burn outs.
