Very interesting topic! Tomorrow i am going to tackle my e-brake kit from Lanner and fit it to my chassis.
Also got to check if i have enough clearance with the spring plate bolts.
I've blasted my arms in my garage with glass beads and then had them painted in LA7W VW/Audi silver grey and coated with a few layers of clear paint. The smaller parts i had zinc plated.
