When do most go to an Adjustable rear shock, like the QA1s or Strange?

 

personally I went to rear adjustabls when I decided to go full race and was having some consistancy problems. C/E make a decent set for a very good price also. But they are not adjustable by turning a ****, removal is required to set them.

 

I have a set of QA1's on the front and KYB AFX 8-way's on the rear.
