I've also now installed the assembled rear subframe. Info about the subframe rebuild can be found earlier in my build thread.
I used new bolts to secure the subframe.
The rear 8 x bolts were torqued to 58 Nm. The same torque is applied to the 2 x nuts that secure the rear bushes the the actual subframe.
The 2 x front bolts were torqued to 175 Nm. Remeber to install the two lower cups too (easily forgotten).
I then installed my new HKS Hipermax S rear struts.
I used new bolts, nuts and washers to secure the suspension. There were also a set of spacers that came with the HKS kit to ensure the correct fitment of the rear stud to the lower suspension arm and associated bolt.
None of the other suspension bolts have been tightened. I'll do that later when the car is ready to be taken off the body dolly and the wheels installed. I'll jack the hub /knuckle to the correct ride position and then tightened everything up.
Final thing was to ensure the ABS sensor leads were pushed up into the cabin from underneath.
