So I have the front of the car already all SPL bushings except for the strut mount bushing, and upper control arm buhings which are whiteline.

Was a decent improvement, but still severely lacking. I've come to the conclusion that no amount of front end bushing upgrades can come close to comparing to the rear end bushing upgrades.

Anyhow I ended up going whiteline in the back, except for the differential mount (SPL) as I could't justify spending $500 for the knuckle ball mounts as the car is a daily driver.

Anyhow all I have to say is holy ****, the car handles so much better with the rear end locked down.

It's like a totally different car. Finally I have the control, and predictability level I was looking for.

Anyhow for those looking, I found this chart to be very helpful.

Get all the bushings upgraded in the back, knuckle ball, subframe, differential, and everything inbetween.

 

Whiteline subframe bushings made a nice difference, so did all my SPL bushing and arms out back. I also installed the W62989 whiteline upper control arm bushings.

 

I went with EnergySuspension bushings through-out the entire chassis F/& R, including the steering rack & diff. What an increadible differance it made.

 

I have to ask, what are you referring to as Knuckle Ball? (I mean outside of baseball context of course.)

 

All those extra groovy bushings in the back of the car. You know the spandrel arm gravity bar side frame bushing?...if you find it, replace that one too.

 

This made me lOL
