Hey Vladamor!
Yea, I remember that splendid time attack Evo. Incredible build and skills that I'm far from matching honnestly. Anyway, I tried soldering steel wire and it doesn't work really good. If I remember correctly that Evo guy build everything from brass rod, which must be easier to solder.
I took the option to stay with CA glue, and painted everything in the color I wanted, after all, it doesn't
really have to be structural, isn't it?
Here is the result:
As for the recaros, well maybe should I detail with more pictures but the steps are quite easy:
-1/filling the "hole" in the back of the seats
-2/drilling the passages for the harness
-3/scratchbuild reclining handles
-4/scratchbuild pivot plates
-5/paint and glue together
Looks easy like this, but it really is. All you need is a good reference, which in my case was easy as I own the real seats :P
Began building a new rear sway bar with soldier wire. Too lazy to comment, here are the pics
Sorry for the bunch of pics...
