Yeah true, it could support a little lowering. I don't know how this particular kit is engineered, but there's a nice tutorial in here about lowering cars, it went very easy on my DC2, maybe it works the same on the RX7.
Anyway, the build is very nice and clean, and I really like that color!
I have a GTC version sitting on the shelf, I hope it will look as good when finished.
Congrats for the work done.
