Hello,

Im trying to raise my rear coilovers, but the rear coils is seperate ( the strut and spring ) what should I do to make the ride height higher? Do I unbolt the screws and lower the LCA or I can do it without taking out any bolts? If so how? Thanks! ( the spring perches is at the bottom of the spring )

 

It's going to be a lot easier to change the ride height if you drop the spring cup. It's only 3 bolts (shock, control arm and endlink) and then you can press down on the spring cup to pop the spring and perch out to adjust the height. They cup also lines up easily when reinstalling. If you have adjustable height shocks with that kit you will need to re-set those accordingly as well. Shouldn't take more than 1/2 hour if you have the vehicle on jack stands and use the jack to push the control arm back up to align everything. Also I know with my Teins all the adjustment collars get torqued to 40ft/lbs, I would imagine yours are close to the same.

 

How do I adjust the spring if my perches is at the bottom of the spring cup? My friend told me the perches should be on top.

 

It depends on the design of that suspension. On my Tein's the spring perch is on the top. I would think generally they would be on top to help prevent the threads from rusting/seizing.

You will have to remove the spring from the vehicle to access it, then move the perch closer to the base to lower/farther to raise.

I don't have a pic with my new Flex Z's, but this is how the rear setup with my old Tein Basis kit looked:

 

Can I adjust my ride height through the strut only? If I move the perches one inch through that metal thing the spring will not fit, or unless i customize my rubber on top?

 

No, that will only damage your shocks. The spring controls the height. If it's too high for you with the perch, there's nothing wrong with removing lock rings or removing the perch/rubber all together, but that might create some NVH in the back end.
