I went off GCs list
ok, from helping mantiskungfu with his pedders/ss/tc swap, you want/need/should get (from top to bottom) :
new saturn ion redline strut mounts
0ttp spacer (glue it to the bottom of the strut mount to aid assembly)
strut mount bearing (comes with mounts)
cobalt tc top spring perch
cobalt tc strut
new end links of your choice
you don't neccessarily NEED the end links or new strut mount, but if the little screws holding the strut mount together snap, you're stuck. if you can't undo the nut on the sway link(common), you're stuck. so, you might as well be prepared.
we also discovered that the spring coils hit each other near the top, causing a clunk in the front. a little bit of rubber hose helped.
you'll also want to lube the rubber spring isolator on the cobalt perch to allow the pedders spring to settle evenly.
that lube will also help with getting the rear springs onto the bump stops.
Q: What's the difference between a bolt and a screw?
A: First, you screw. Then, you bolt.
I didn't order the shocks and struts cause they only have 35k on them but I got:
Ion redline strut mounts and bearings-last they had
Cobalt Pedder springs
I found a discount code and got em for 322$
Powell ring sets.
