Mounts theme continued

Have heard comments about 034efi solid motorsport engine mounts from very respected person. It was more like horror story, not the comments. Excessive vibrations, bolts loosing tension under vibration , etc. Nylon theme is suspended a bit.
Also had a chat with rally guys. They told me, that load's of ppl are using old 4x4 VAZ engine mounts for rally. Which are silly cheap - about 3$ each. Went to local parts store, and bought some. They are damn too small:You can clearly see, that those 4x4 mounts are solid rubber. Russian made things sometimes last very very well, no matter how crude they are made :). The problem is, that the thread is using M10x1.25 pitch (normal mounts use conventional M10, which is 1.5). Also mount heigh, if I want to put it in the old "cup", is almost twice shorter than needed. Will need to think some strong and elegant solution (it will turn to be weak and horrible to make - as usual :D).

Also manged to change toe settings a bit on the front. Don't know if it's related, the car responded with better turn in to the corners, however horrible vibrations on the steering appeared. Maybe I have tightened wheel incorrectly. I hope so.

Cumulative update for september :)

Progress is going very slowly (like it used to be). Only things, that are seen for experienced eye are changing a bit ;). Like patching and fixing things, that were made not so good and in the hurry or inexpierence.

Further steps in my motor mount construction. Tried to fill empty motor mount with nylon. Main focus was to fill the edge, where nylon can get grip with the alloy part. First it looked okay:
After some home brew machining - it is not looking so good:
Will try to improve construction a bit. But it will be later.

Also there were some tries with new brake setup. 996 caliper fits volvo disks - very nicely:
But who will make caliper carriers. Now I'm trying to master CAD software, just to draw something for guys, who work with metal...

Main job, which I was forced to do was to rearrange fusebox a bit. It was purelly unsafe. Now it is much more safer from electrical point of view (in insulation terms of battery power terminals 30, which can bring fire immediattely after it touches roll cage...). It is still hanging on tie straps, however making some more solid fixings would take too much time and would improve result only by a fraction. White straps will be replaced by stronger black ones which were bought after doing this photo ;). I can even put cover on relays. One thing, that whole construction still is in very uncomfortable position regarding left leg. There is enough room for the operating clutch pedal, but it's tight fit:
