That's because MC car is difficult to overtake on the racing course.
Actually, the number of times Tsuchiya has overtaken over two years is zero car, the number of times he has been overtaken is more than 50 cars.
It is because the engine power is less than 100 horsepower than FIA-GT3 cars, and even if the car weight is 150 kg light, that does not benefit much in racing traffic.
In short, MC car is quick in single running, but it is easy to be overtaken, and it is difficult to overtake.
Therefore, in order to win with MC car, you have to either run alone from the pole position or shorten the pit-stop time.
They have developed tires in cooperation with Yokohama since 2015 to make no-tire-change strategy successful.
And that tire was completed in the early part of 2016 season.
However, Tsuchiya thinks that it might force their racers to overtax their tolerance.
He thinks whether it is good to restrain overtaking for young drivers Tsuboi and Matsui.
Considering the financial side of FIA-GT3 car in the 3 year cycle,
it is necessary to double the MC car's budget.
Therefore, Tsuchiya of privateer can not afford it.
In order to win with MC car, it is only necessary for two quick drivers.
However, in order to be a champion with MC cars,
two drivers who can drive quickly and can control themselves are needed.
In other words, of course #25 MC car is quick, but Tsuchiya's drivers are quick and amazing.
Having learned Tsuchiya Engineering's deficit on number of full time staffs, power deficit in its car etc, I'm amazed the team can backup its own weakness with excellent strategy and drivers. Especially at 2016 last race. Such the old-school team.

I always root for the little BRZ, hopefully they keep these updates coming. Can't wait for Suzuka.

Impul really seem to be struggling for pace this year, is it because the GT-R is designed around Michelin's ? and does Hoshino's association with Bridgestone prevent a tyre change?

Well, speaking about GT-R x Michelin tyres, I don't think that combination means immediate success. The #3 car from B-Max NDDP still struggling just like other GT-R GT500 cars.

I prefer to think that the combination from the team, manufacturers, tyres etc is the secret of the success on the race especially for #23.

Autosport web reports Shinichi Takagi (#55)'s secret technique in Qualifying lap of Fuji round.
http://www.as-web.jp/supergt/367554/2

Takagi ran the qualifying lap by switching the ABS mode (Wet/Dry) for each corner according to the different road surface mu.
Very clever veteran's technique!

Car Watch SGT tire manufacturers interview
Michelin (Hiroaki Odajima)
https://car.watch.impress.co.jp/docs/news/1121630.html
*Michelin continues to participate in Super GT because there is a competition field.

Bridgestone (Koji Terada)
https://car.watch.impress.co.jp/docs/news/1121675.html
*We have not yet solved why pickup phenomenon occurs only in NSX-GT.

Yokohama (Shuichi Fujishiro)
https://car.watch.impress.co.jp/docs/news/1121738.html
*In fluid simulation, side wall fins have the effect of reducing air resistance, lift reduction effect, and as a result we found that there is an effect of increasing downforce, so we had introduced it in GT500.

Dunlop (Tanigawa/Imakita)
https://car.watch.impress.co.jp/docs/news/1121773.html
*The cause of the Suzuka 1000km race is that our tires matched the road conditions in the latter half of the race and Kosuke Matsuura marked fourth possition in Q2 session.

It's a disgrace as far as I'm concerned. One of the best races on the calender made into you another GT3 snoozer.

Me too. Im a big fan of the JAF GT300 cars before the mother chassis came along and the Brz is a nice example of the individuality of those cars, I like GT3 being part of the class but have always admired the home grown stuff you never seen elswhere. Plus I always liked the Impreza and the Legacy that they ran in the past.
