I envy you.
I'm already regularly checking when this kit hits the stores. And it's nowhere to be found. Unless for you, of course...
Anyway, nice of you to show the contents of this kit. Now I know what's in store for me.
What I couldn't really make out in the pictures is how well the brake discs are detailed (if detailed at all). In your pictures they seem just plain plastic with no grooves or holes moulded into them. It would seem that Tamiya is going the same route as with their latest kits... ie. skimping on the details to make you buy their PE set with brake disc detail...
I hope you can prove me wrong here.
The other PE fret (with the grilles) comes with the kit, if I read the text on the box right (see 1st pic in 1st post, white text at the bottom of the box).
Will be following your progress closely !!!
