my car butterflies and i want to get some cambers but not sure which is good. theres the bolt ones and the arms. anything will help. thanks.

 

To my knowlege, if you have spring/shocks combo the stock adjusting bolt should be good enough for camber adjustment.

If you have coilover and dropped it more than 1.5 inches then a Rear Upper Camber Arm RUCA would be needed. There are expensive high quality RUCA's by kazama and other jdm companies and then there are the EBAY RUCA's that are similar to alot of other brand's but might lack quality. I myself bought an ebay one for 100 something dollars. Works well so far but i haven't really driven it hard. The price difference is huge but you get whatyou pay for i suppose.
