Hey Klutz awesome work you've done there, good to see some of the MFH kits actually being build!
I'm building this kit too at the moment (Silverstone 05) but do you know the funniest thing? The progress pics look almost the same, I cut out the vents, drilled holes in the louvers, made air jack parts, drilled out the exhaust...and so on
One thing you should check, I saw on one build here that the left rear wheel was way to much inside the fender. I got the same thing on my kit, so I fixed it with some some new turned spacers for them. Here's a pic

the first two from left are front, then right rear and left rear which shows clearly that I needed a way longer spacer.
Which color will you use for the rims?
Oh by the way really good idea soldering the roll cage I might try that too..
My WIP will be up as soon as I painted the first layers green
