Appears to me that it's too tight and you are shaking it loose.

Bob East had the best observation I have heard about race car drivers and them telling you how the car feels....I'm paraphrasing some...but Bob said that most drivers only remember what the car did last and that isn't always what the problem with the car is. Meaning that if they are telling you that it's loose....often times it is actually tight and the driver is making it loose. Without seeing a full night in person it's hard to tell.

Just remember that little changes in
Driving can make as big a difference as changes on the car.
