Yep that adjustment will be enough to get you within oem spec if only on eibach pro kit. Sorry, the J power, while cheaper, isn't half the price when buying the camber arms only.
What I should have said was for the price of the SPC 1 arm kit (1 degree adjustment), you can almost get the 3 arm J power kit (3 degrees adjustment). The 3 arm SPC kit costs around 400 ish.

The megan ones are overpriced for whats supposed to be a budget chinese name. SPC (eibach) are cheaper and are a better name.
