Sure the ride is softer and quieter, though the car is bouncing all over place and forget precise cornering, I now lack confidence in hard or fast cornering.
As a person who has modded a few cars in the past (mainly VAG cars), this is the first I have found such a terrible response from just changing tires.
I am now confused on how to correct this and have read so many different responses on this issue.
I was thinking that from my past experiences that it be best to get a set of KW V3 coilovers rather than playing around with so many factors and see if that can maybe help the car get back to a least a spirited ride.
The bouncing is caused by the OEM dampers being tuned to the rock hard run-flats. Coilovers, while nice if you can afford them, are unnecessary. a good set of Koni/Bilsteins will fix you right up. I got my Bilsteins for $470 from Bavauto.
