Before i dive in and change my setup again i would like the opportunity to see how it rides.

Fyi i live in Clarkston so metro detroit area would be preferable. With the dream cruise coming up it may be easy to meet up, shoot the sh$? And talk cars

Thanks in advance

Hey Marcus,

Sorry to hear about your back. I literally feel your pain, as I broke my back in a racing crash in '91. Hurts everyday. Some days less & some more.

As far a ride quality goes, the linkage system will have very little contribution. Regardless of brand of 4-link ... or torque arms as some like & have mentioned ... the ride quality is going to going down to:
* Getting rid of the articulation bind you have from your ladder bars
* Getting away from solid rod ends & monoballs & going to something with softer bushings, preferably Delrin.
* Spring rate
* Shock valving

If you're not going to autocross or track the car, I would suggest a rear spring rate around 175#.

For shocks, you want a monotube shock with relatively low rebound & compression rates in the 5" to 20" per second range. That is the range where shocks respond to bumps & dips in the road. IMHO, I would not "save money" by buying the lower cost twin tube design shocks. They can not provide the same response rate & ride quality.

In my experience from dyno testing all the shocks commonly available in the PT world ... the off the shelf Ridetech singe adjustables will provide the best control & least harshness. You want the single adjustable shock to dial in the feel to want you personally find

All rear suspension styles ... 3-Link, 4-Link, Triangulated 4-Link, Torque Arm, Truck, Arm, IRS, etc .... ALL have differing pros & cons. If you want to talk grip ... not ride quality ... bring that up. Otherwise, all will work. And all of them can be made to achieve your ride quality goal.

As far as which 4-link ... or other suspension style like Torque arm ... I'd make sure they have delrin bushings, easy pinion angle adjustment & a quality reputation. From there .... IMHO ... it would come down to dealer relationship & customer service.

Best wishes.
