adjustable control arms?

[AUcobra94]

I am going to buy some UPR control arms in the near future. I was just wondering if it is worth getting the adjustable ones and do you need both upper and lower adjustable or just one? thanks

You dont need both but it would not hurt to have both.

You don't "need" adjustable one but if your trying to sqeeze evey little tiny bit out of your car while launching then yes. You can use the stock uppers just replace the bushing with poly's.
