Are the mounting holes straight across like the stock one or offset one higher than the other like iX booster?

In a sense they are straight across, but the reservoir would be diagonal ;)
The bolts are spaced further apart and diagonal.

They are also two different sizes arent they?

I THINK the piston size on the ix master is the same (22) as the regular 325i, ill take a look but cannot remember off the top of my head

I was more so referring to the ports. I think one is large than the other on the m3. m3 has a 23mm piston doesnt it?

ah, the piston size on the m3 should be 25mm, it is the same part number as the 750i e34 which uses the 25mm piston ;)
