So I've put coilovers on and at nearly the highest setting I'm maxed out at -3.2 degrees of camber
The car has a camber kit of some sort, I'm assuming Eibach since I bought the car from the PO with Eibach springs.

Are there any control arms that I could dial in +1.5 to +2 degrees of camber in the rear? I've seen the Exact RCA, but I'm not sure if my coilovers at their highest with another 1 inch drop from the RCA will be a desirable ride height. Just want to see my options, but if I have no choice I guess RCA it is.

 

I'm pretty sure you can dial in positive camber with any of the adjustable control arms available: FIGS, SerialNine (only goes to +1), TCSportline (for IS300 but fits our cars), and of course Ikeya and the other JDM brands.

 

You cannot get anywhere near stock with SERIALNINE front uppers. They are -20mm shorter than stock.
