Racing is 90 percent mental, the other half is preparation.

That’s what I thought at first but what could be bent that would affect both sides equally? Seems strange to me that both LCA could be bent the same.
I hate to offer this explaination, but both LCA's are attached to the sub frame. If it's bent in a "bellied-up" mode it would give you the result you're seeing.

Is there any way to measure this and specs I should look for? I would like to be sure before dropping $400 and missing my first race.
As Charlie mentioned measure & compare to another hopefully known good sub frame. For a tool look at Advanced Autosports tools, Dave Wheeler has a fixed tool to measure the rear eccentrics. Make a similar tool out of wood with one end being fixed & the other end being a pivot. Just like with a measuring caliper touch the ouutside diameter of the two ecentric bolts, carefully remove the tool & measure with a tape measure.

Point being, you might have a helluva time trying to figure out what really is bent but if you suspect it's the subframe and plan to change that, consider that the LCAs probably bent also in whatever event bent the freakin huge piece that doubles as the engine support, and be ready to swap out the little bent up sheet metal bits that hang off it holding the bottom of the upright too.

I was attempting to set up my new to me 99 this weekend and I ran into an issue with the front camber. I can only get 1.9 on the left and 1.7 on the right. The ride height is 4 5/8 and it is 50% cross weight. Any ideas on what can be off or what I may be doing wrong?
I am new to SM and I had this same problem last year
But mine was an easy fix I didn't have blue printed front spindles

The most camber I can get in my car with a brand new subframe and new LCA and upper control arms is -2.8. That was at 4 1/4" ride height. YMMV.

What are you using to take the measurement, is the floor totally level? I was doing measurements on my lift, I leveled the lift., but on one of my ramps there awe a bit of flex, which distorted my numbers.
I was using a set up pad that I leveled with a laser level. I then used a longacre caster camber gage and the angle gage that came with the iron canyon complete kit.

Also remember a hard and fast rule about alignments and suspension geometry.
Suspension WEAR always results in camber going more negative. This means that you certainly dont have any worn bushings or balljoints.
