not trying to hijack anyones post.. just posting info upon what people are speaking of...
if the pineapple is like the SPL subframe spacers then this is from their site:
Subframe bushing spacers are used to tilt the subframe to change the rear suspension squat/anti-squat characteristic. Increase squat for drag racing or anti-squat for drift. These spacers cannot be used in conjunction with the collars above, but can be used with our solid aluminum bushings below. We recommend these spacers for drag/drift, and collars for circuit and all-around use.
Set includes 2 urethane (larger) top spacers and 2 urethane (smaller) bottom spacers. Install the top spacers on the front subframe bushings and bottom spacers on the rear subframe bushings to increase squat. Reverse to decrease squat.
