I have a couple of questions about coil overs. The rear coil overs I bought are an all in one design (spring and strut) I asked the guy over at the company I bought them from (ksport) if I would need to get a replacement for the rear lower control arm (the bucket thing that the original springs go into) and he said no I could just delete it and not replace it. Is this right?

My 2nd question was will i need adjustable end links ?...I bought the stillen RSB and I will be doing all my end links front and back so I really need suggestions for good quality long lasting end links plz
