Now onto the s13 to s30 coilover conversion!
- Prep the coilovers you just bought:
- Remove lower perches
- You can choose to cut off the s13 mounting brackets (They do not interfere on the Z, but removal makes for a cleaner install).
- Measure how much smooth tubing is inside the perches (from the bottom, before the threads). This is how much of the Z strut tube you'll want to keep when cutting the Z struts.
- Cut a notch in 2 of the perches. This is to accommodate the notch on the spindle that prevents the perch from sitting flush on the hub spindle. (dremel can be used as well)
- Remove top hats
- Thats it for the prep
- Disassemble your factory strut/hut assemblies.
- Factory service manual comes in handy now along with a spring compressor.
- Cut off your Z struts
- keeping 1-2" of strut tube left depending on your previous measurements of the coilover perches)
- PRESS on 4 front perches onto the remaining section of tube.
- This will be a VERY tight fit, so you'll need a press. Press it on all the way flush to the base of the z car spindle.
- You can now weld the tubes in place on the spindle.
( it is suggested that all welding be done by a reputable welder or shop... The welds are the most important part of this conversion, and if done wrong, the suspension "WILL" fail. It is suggested that welds be done by TIG, for the best weld outcome.)
- Now onto the camber plates.
- Start by unbolting the front fenders. (10mm bolts)
