B44 - alloy caster blocks FT9721 - angle?

[elektrobuggy]

Hello, first of all sorry, if this answer has already been given in the forum and I have overseen it.

Do the alloy parts ae #9721 have a different caster angle or is the same as the original one?

This parts provide stiffness (plastic is fine as well) and the major feature, to adjust the rollcenter by washer with pretty easy access.

Thanks for your answers in advance
