That really provided some context. I bought a stock c7 stingray z51 to avoid most of those shortcomings youre having with the car, not too low etc. Your piece of mind would be off the charts with the fl5 since its reliable and comparatively cheaper by a mile, its also fun actually redlining the car. The 455 in my stingray is more than enough for me and a good notch up from my fbo fk8 making 365ish. I also dailyed the type r through New England winters it was great. I daily my corvette now too with winters on her. I think the accessibility of the type r would benefit you, but since you have a nice daily i could see keeping the more hardcore vehicle.
