I don't know in which of the two threads about this kit it lives in, but someone gave the advice to putty the underside of the roof first and then clean up the shiny side. Having one of them myself, that seems to be the most reasonable proposition for fixing (and affixing) the T-Tops.
The only "unfortunate" thing about the decals are there's 3 or 4 that have various printing errors and they had to run a supplemental sheet, and I'm not sure how many North American kit owners even knew about it. It took 2 1/2 months with 0 communication from Fujimi to get my replacement sheet, but in the end I DID get it, so I can't fault them.
If the tires being aftermarket units on the 1:1 they measured are the biggest offense the new Bronco can come up with, I'm willing to take that everyday and twice on the weekends after that little era of "Blech" that happened between 2012 & 2015.
I dunno the kit grille and the yellow car don't look that far apart to me. I have to wonder if some of the "tallness" wouldn't be rectified by painting the argent surrounds and black grill areas. There's just a lot of uniformly SHINY chrome OOB, and have the color transitions might help draw your eye away from how it looks as a single piece. Sort of the way painting and foiling a '56 Chrysler makes that kit "lose" the odd hump it has in the roof that is pretty prominent on the raw body.
Studio27 already has relationships with Rowe Racing, Walkenhorst Racing, Schubert Racing & Boutson Ginion Racing which are all running the M6 in the Blancpain Endurance Series as well as the 2016 24hrs of Nurburgring from a few months ago. There are also 2 teams in Super GT using the M6, but Studio27 hasn't done much with Super GT, most likely because Fujimi was doing so many things like the Studie BMW Z4 as kits. Studie is running the M6 as well as the Autobacs team.
This kit popped up on the Japanese vendor lists this morning with an "After November" release date. ICM usually distributes globally to all locations at the same time (as opposed to RevellAG kits hitting Europe 45 days before the U.S., or the 4-6 month lag between U.S. releases and their Asian distribution). So you will probably be able to ring in the New Year with a new fire apparatus. With the exception of Squadron who occasionally firesales ICM kits, the cheapest way to get their kits continues to be via Ukrainian distributors on eBay.
I don't think anyone would even consider making a new tool kit that a further variant would permanently alter the tooling. Unless you're talking about Round2 "demodifiying" things back to their origins. Heck when Revell reissued the Yenko Nova last month they didn't even put all the "COPO" parts into it to correct their original gaffe...even though they have the parts, and the COPO Nova kit has most of the SS parts in it. They would have just had to include the original hood with the louvers and the Yenko decals in the COPO kit contents. But no they reissued it completely wrong like the original, meaning you still have to buy that COPO kit separately to "convert" it. Nobody, especially Revell is destroying tooling.
