Alright a quick update - I buttoned up the front suspension and back on the ground.
Replaced the following;
Upper control arms
Lower control arms
Sway bar links
Tie rod ends
Upper and lower coil spring shims
Springs upgraded to DINAN
Bump stops upgraded to DINAN Stage 1 Rev.A
Rear sway bar links
Height sensor rods - center-to-center set to 69.4mm per DINAN recommendation
I had to replace all 4 bump stops and fronts were somewhat straightforward, while doing the rears I had to take off the struts and the strut bolt that goes into the swing arm wouldn't break lose, after numerous attempts and with a long breaker bar I broke it lose but turns out the threads are gone, not sure if it was overtightened by whoever took them off last or galvanic corrosion played a part here - replacement swing arm runs about $600 a piece and they're both shot - used off of ebay or part-outs cost around $150 each. I plan on using heli-coil to fix it rather
I wasn't expecting this setback but I'll continue to make progress with other things, I haven't even had the chance to get to removing exhaust manifold and downpipes for ceramic coating.
Will update later on.
