Default Alignment Question. Suspension Gurus please chime in

So i just finished replacing my rear knuckle bearings thanks to FIGS Engineering and working on getting my car perfectly dialed in and track ready. I have BC coil overs, f sport ways, figs mega arms in the rear for my mechanical suspension upgrades. After aligning the car, I have about 1.7 degrees of camber on my front left but about 2.7 degrees of camber on the front right (negative cambsr of course). Doesn't it seem odd that the natural camber from the drop creates a full degree difference of camber from side to side? I am planning on going with a camber kit upfront but with that much difference in camber from side to side, I am starting to think that there may be a problem and it isn't just natural camber.

Any feedback suggestions, advice would be much appreciated.

Could my car's height side to side be off as I have not corner balanced yet causing the imbalance? Could a broken ball joint or something create this situation. I don't want to order a camber kit to fix the alignment if there is a problem itself causing the difference in camber
Thanks for the help everyone!

Yeah, I'd say that's totally not normal. When I dropped my '06 IS350 on BCRs, I had 2.8 degrees in the rear and 2.3/2.5 up front; nothing as far off as you there. I would start checking out things on that front right for previous damage.

Let us know what alignment specs you end up going with AND what process you use with the corner balancing. Some of us that care about taking our 2IS to the track would love to hear what you've done and how it ends up working out for you.

After being lowered, what is your fender to ground measurement? Use the highest point of the arch of the fender. I would have to assume the smaller 1.7 degree measurement is accurate and that side is "OK". 1.7 degrees isn't really bad at all; if anything, get both sides to as close to that as you can and zero out the toe is possible.

It could be that your front subframe is "off". (as in forced to one side or the other)

That doesn't look normal after a drop. I too have BCR coils and f sport rear sway. My drop is basically the lip of the fender level with the top of the tire and my camber in the front right is -1.8 and front left is -1.6. In the left rear is -2.3 and right rear is -2.4.

Not perfectly even camber on both sides but not as far off as yours is.

Good luck looking into this.
