Most people use camber plates to gain negative camber on their BMWs, but you can also increase negative camber using an adjustable length wishbone/lower control arm and making it longer than the OE arms.
Other benefits of lengthening the wishbone/LCA are increasing caster, and increasing the track width. The caster increase helps maintain higher negative camber when the wheels are turned, and increased track width reduces roll on that axle. For reference, BMW increased the front track width on G8x by 1.5" over F8x (and the rear by only 0.2").
Using these arms with the stock springs/struts I was able to achieve -2.3deg of negative camber at max extension, which produced about 8deg of caster, and widened the track width by 1".
Here's an overview on these arms, their features, and how they work.
