Opinions on rear coilovers?
What does everyone run on the rears? I've heard very good reviews of Viking, but would like other opinions. Strange, QA1's, etc. Car is a 99 Z28. TIA.

Hello,
There is really no cons to running a rear coil over kit, performance wise. The pros are you have ride height adjustment, also the availability to swap out spring rates if needed very easily with many options. Running a good shock and a good standard spring can have the same performance results of a coil over. I really can't think of any cons to running the kit...
The UMI kit uses the Viking shock, it is a double adjustable shock with 19 compression and 19 rebound settings. You can basically adjust the shock for drag, street and handling by just clicking. We then offer three spring rates we found best. The kits are bolt in with two holes to drill. We also include a spacer kit that allows our rear end brackets to work on most aftermarket rear ends and to work with already installed control arm relocation brackets.
Here is the kit, also below are some installation pictures as well. The last picture is the UMI test car that ran this kit all season, no hiccups!
We also have a new front kit coming out very soon, might want to stay tuned

When Viking came around it was kind of a game changer as they have DA with 19 adjustments on compression and rebound added in with the two year warranty.
We sell a ton of all the brands still to date so if you have any questions please feel free to give us a call to help get you into what you need.

Can't go wrong with Vikings. They are great products at a great price, and have a ton of adjustability. However, one thing to be mindful of the upper mounts for the rears. There are 2 styles that are offered. I have heard several complaints about the stud mount top that goes through the factory shock hole. The best setup is like the bracket UMI posted that braces over to the spring pocket and has a transverse mount with the bolt in double shear and a bearing on the upper end of the shock. This eliminates binding, noise and distributes the load across a larger area. This is the style that we offer as well. Shoot me a PM and we can talk pricing and see if I can set you up with some for less than you might think

We have been selling stock style upper mount coil over from Strange, Afco, and now Viking for a long time with out issue. I'm glad you are happy with everything you purchased so far.

Heh..... Lets take our cheerleading dresses off for a second....Lets get real. The OEM shock and spring move on a bolt or piece of rubber top AND bottom - just for reference. MWC moves on a bolt on the bottom and a rubber bushing up top. The up/down movement is huge, lateral is near zip. It could be near hard mounted and I wondn't really see the issue. Imagining a rear end articulating.....no need for a bearing mount in my mind.

For those that are not concerned with noise that a solid upper mount will create we also offer an upper mount to convert to a bearing and been doing it for years but most street driven vehicles choose to do rubber mount upper. We have been selling Strange and Afco rear coil over conversion shocks for years with stud mount upper and now that we are selling Viking we sell them the same way unless while discussing an order with a customer we go to bearing top.

As for lateral movement, the control arms and torque arm will swing on an arc, so any compression or rebound of the rear suspension will make the axle move forward and back some. True, not much, but enough that it does need to articulate. Granted the front uses a similar design, it also floats in a large isolator bushing, in a heavy plate mount.

All true, and good points. Its just, the backs of these cars aren't heavy, and though I haven't looked closely, I suspect structure is similar around the OEM coil and shock locations at the body, and we know they reside physically close to each other. Meaning, if the area for the spring pocket is reasonably stiff, and the shock mounts a few inches from it, its reasonably safe to say thats not paper thin.
