I have checked everything I know including the length if the turnbuckles(steering, and camber) the caster block is spaced correctly and has the correct caster insert. All of the ball studs are in the correct place with the correct washers. The shocks are in the correct place,middle on top outer hole on arm and shock collars have bean measured to be equal on both sides. I have even diss-connected the entire front clip to see if maybe the chassis was tweaked, and I could still see this huge camber difference by eye. I have swapped the setup wheels side to side, and used rim with no tires too see if they are to blame. In order to have 1mm camber on this side I need to have the length in between the ball ups at 24.5. Has anyone experienced this before or have any ideas?
Is the chassis level with the surface side to side? If the ride height is slightly higher on one side, you could induce enough camber gain to have a difference between sides.

Also double check that you put the same caster inserts in the front hubs. Along with the trailing arm pills are equal on both sides are installed correctly ( make sure there wasn't any flashing to keep them from sitting flush, if you didnt glue them in there?)... Let us know.

Yes!
A camber gauge should be one of the first set-up tools a guy should buy!
I never even go by the manual recommendations when building camber links.
I always shoot a lil black grease in the end, get the turnbuckle started and run it in a certain amount of turns, then do the same for the other end. When the kit is built I throw some tires on and get out the camber gauge and set them to my usual settings for the track (usually -1* up front and -1.5* to -2* in the rear). The manual settings are merely a suggestion and shouldn't be the set in stone setting as they will be way off!

I did check the trailing arm pills, and caster inserts. I wasn't really going to stay with the kit settings for camber anyway but everything should be even side to side or close enough that you can't eye it. I use the de racing setup wheels on a glass table to measure the camber so the readings should be accurate enough. But at this point I feel like I checked every thing. Any other ideas?

Is your trim set correctly? If your front tires are turned even slightly your camber as measured to the surface will change. You have to check the front camber with the car and radio on and steering centered dead-nuts.

Good tip, but I definetly measure with everything on and centered. I do notice the steering block has a lot of up and down play within the caster block, especially compared to the fit on my b5r. I took the entire front clip off of my b5r and bolted it up to the chassis of the b5m lite and did not have this issue, so I think the chassis is straight. I would really hate to just buy all the plastic on the front and replace when it's brand new

I checked and the cups are the same with the total turnbuckle length being 76mm.

Upload a picture if you can. It will help troubleshoot.

Wow and I thought my OCD was bad... I'd just set the camber and go.

This is a must to have the radio on and steering centered....

Ok I just swapped the front shocked left to right and now it seems like everything is ok as both are around 3 degrees so I can adjust from there. I still don't know what was wrong but at least I know the chassis isn't tweaked. I'm not really super OCD about cause at leAst I don't feel that you can ever set thing 100% the same left to right but it should be close. This was so far off before that I knew it would never be close. it it's just that if the something isn't right I know I will just be chasing a setup and it's easier to find out now versus after running it. Thanks to all who responded as it was all good stuff to check.

I'm trying to understand how swapping the shocks would affect it at all? From your post I started measuring my car and noticed some differences left to right. I do know I had a hard time screwing the ends onto the pistons so I doubt they are even.

Me too, I just run them all the way in then back them off when wheels are on.
