Very nice! This mod let the bastion has a lower and a higher version.But there is one small thing is can you make to turn off (Sorry I don't know how to explain that)the SCR's V10 turbo while in Caged mode?
Anyway it's very good
This mod is just fine its is form right here is adds a excellent V10 engine, and a bunch of extra trims.
There is more potential to it though, in my opinion you could maybe add:
Different type of turbos to the V10 engines
More tuner parts like different bumpers, exhaust.. Underglow if you like it
Lastly maybe A pre-facelift like 2011-2014, like what you do with other small packs..
Just some ideas.. Hope these enlighten you. have a great new year!
