so in a few weeks i will be ordering my upper hpm control arms. the lowers were great quality and worked really well so far. so now here is the question. hpm makes a single adj. upper conrol arms and a double adjustable upper conrol arm. the single is only 219.00 for both and the double adj. are 260.00 for both. what ones should i go with?

Alot of people say that theres no need for upper control arms. I'm not exactly sure why but thats what they say. I have the steeda double adjustable upper control arms and they seem to be pretty good but I did break a bushing on one of my first runs this year.

i dont know why people say odnt do uppers as well. the uppers are what adjust the pinion angle (thats what i was told) i think im just gunna go with the extra 40 bucks and get the double adjustable ones.
