I say buy tools and do it yourself. That way if issues arise like clunks and squeaks, you can diagnose it yourself rather than relying on a shop. The first time usually takes longer but it gets easier every time you need to remove and reinstall.
So I was on the phone with Tein today... Now waiting for them to analyze my pics and see if it can be fixed/replaced. How important is that top part (from the first pic)? Will I be able to use the coilover without it? There's still space for the lug nut...
" The broken piece is part of the piston rod. The piston rod is very important to the coilover application an should not be used in this broken condition. You would need to send in the damper for repair, starting price is $75 this covers the clean up replacing he seals changing the damper oil and labor. The new piston rod will cost $55 and would have to be ordered from Japan*... " Not sure if I should try to install them again by myself lol.
