Thats what i thought.
With the new promini - they clearly say its supposed to protect against mushrooming with this 'new' brace. But doesnt say anything for their original one.
Are they on M2? perhaps they could shed some light on this?
M7';s brace apparently protects against mushrooming from reading their comments.
Havent read anything about
JCW and this issue, and didnt bother looking for whiteline.
