Quaife installed short review
 

wow just got the quaife installed, every things seems to have gone smoothly. My mechanic also changed the crossmember bushing since they were broken.
Alt normal driving, there isnt much difference. Once you gun it on a turn you can fell the grip and the push.
The car just grips better at the rear end.

You should feel it from a break start as well, love mine, grips like a baby on the breast.
