Camber/Caster Plates

[E9madada]

I'm planning to install Camber and Caster plates on the rear axle.
There seems to be two variants as pictured below, any experience/preference of which is best would be appreciated.

I have a lot of difficulty with the version on the right getting them to hold position. The through bolts and grooves are not robust enough to deal with the forces involved.

Noticed they have exchange subframes with what I am assuming is this same adjustable alignment kit installed.

Is this a track specific kit , or of benefit to the average setup?

There is a small benefit from additional negative camber in the rear, but your tires will wear much more quickly. And as I noted, the setup I used was unreliable.

I wouldn't recommend changing this. Spend the money on tires.
