Right hand Caster out of alignment

clkio

Hi guys, 4 month ago I bought my used 2009 370z, the car was completely stock. I recently did some work to the car including swift springs, koni yellows shocks, spl rear arm and spl upper control arms. At the alignment shop, the tech could not get the right hand side caster to be within spec. the driver side caster was 5.5 but the passenger was 7.5 (WAY TOO HIGH). The 2 degree difference in caster at the front now is noticeable when you try to steer straight or brake over a bump.

I am very pissed about this, I tried looking under the car to see if I notice anything bent like a control arm or the knuckle but it's hard to tell by looking at it when it's only a degree or two off. Should I go to the dealership or a bodywork shop? I did lots of research about this but mix answers came out. any help would be great guys.
