2011 Japanese Super GT - Page 22

Japanese Samurai · 12 Sep 2011, 02:23 (Ref:2954194)

In qualifying, because of marshall's instruction mistake, Wakisaka lost the warming lap in the Super lap. However, he got 4th position.
In race, 1st stint was Couto. He battled with Lotterer(#36), and used up rear tires only by 7laps. And he lost the position (4th to 14th) during 19laps.
Wakisaka drove long stint (36laps), managing tires. And he finished in the 9th place.
After the race, it became clear that the right rear suspension was loosening. It is not uncertain whether this mechanical trouble caused wearing of tires.

**Jiro Takahasi(pit reporter)'s Fuji round report

Fuji is a home circuit of Lexus. By the excellent engine power of SC430, Fuji round became a match race by SARD(#39) and CERUMO(#38).
Tachikawa of CERUMO showed us the veteran's work in 2nd stint.
Since the pace of Iguchi to go ahead was very good, he saved tires for the end of a race.
The turning point of the race was the tire burst of Nakajima(Tom's #36).
The last corner became the yellow flag section in this accident.
Iguchi slowed down in this section more than needed.
Thereby, Tachikawa caught up with Iguchi and overtaked him taking advantage of the grip of saved tires.
It became a bitter experience for young Iguchi.

**Tsutomu Tojo(Engineer of Team Tom's)'s Fuji report
In qualifying, we Lexus had good results. Our straight speed was 2-3km/h faster than rivals. Possibly rivals had shifted to the setting of middle downforce from the less downforce. When success ballast was taken into consideration, the speed of #6 and #36 was conspicuous.

However, our race result was terrible.
The analysis at the present time is as follows.
The tire which TOM's chose was a basic tire that there are no other choices in Fuji. Other BS users must have made the same choice.
Lotterer saved the tire from start to the traffic of GT300. Then he put on a spurt and took a 3rd position. His pace was constant during 22laps.
However, the pace down began from the middle of Nakajima's 2nd stint because of tire wearing. And finally the tire burst and the race is over.
As for each Lexus teams other than #38, lap time had fallen rapidly.
According to lap time data, it seemed to be a hard condition for the Michelin user, too.
The competitive lap time of #38 was of experience of Tachikawa.

We were simulating the pace faster than the actual winning time. However, actually, it was a road surface condition very hard for tires. So our mismatched machine setting causes tire wearing, then possibly the rapid lap time down occurred.

I love the aero developments these cars have, hopefully they don't get rid of that aspect in their future.

LEXUS TEAM PETRONAS TOM'S this year has been a bit of a disappointment, but hopefully next year Lotterer/Nakajima duo snatch the championship.

Corvette Z06R of Run Up Sport (#360) seem to revive from AUTOPOLIS round.
Since the crashed machine was unfixable(!), they purchased alternative chassis.

According to the team staff's tweets, it is a chassis of a former "Red Bull" car.

Must be the one that participated at the Spa24, pretty sure it raced in the Belcar series too.

This is a default rule of this season.

2-6 round: driver's point*2 = Success ballast
7 round: driver's point*1 = Success ballast
8 round: No success ballast

So i just registerd because of my interest in Supergt. Not many forums has discussions on it and this is the only forum i saw with an indepth knowledge on the series. One question i have though is about the DTM/GT500 unification, is that still in the works? if so when is it going to take effect? and how will the series shedule change? (will they still race in japan exclusively or will some of their races take place in europe?)

TF110 · 19 Sep 2011, 19:56 (Ref:2958208)

No one knows surely if the two series will combine. At least we haven't heard yet.

**Keinosuke Taki's SGT report -Fuji round review-

In Fuji round, #17 ranked 3rd, #1 ranked 4th and #1 gained 8 points. We demonstrated the maximum performance in the very hard condition.
We were able to show you the interesting race, too. 2nd place battle of #17 and #12 was not able to look aside to the last. Tsukakoshi did the battle to Matsuda calmly to the last.

We challenged the Fuji round with confidence.
In qualifying, Lexus has dominated top 5. However, we had chosen qualifying tires based on use in the race. This choice caused the result as expected.

About KEIHIN (#17)
Kaneishi can't increase his pace in 1st stint. There are regulatons which must start the race with tires used in super lap. The tire which got warm once and was cooled may often be unable to demonstrate original performance. It seems that the problem occurred in #17 (same problem occurred also in #32/Michigami). Therefore, #17 did the pit stop a little early. This strategy went well.
In 2nd stint, Tsukakoshi caught up gradually and took 5th position in 35laps. By this time, he has passed #1/Kogure. We did not order him "team orders". I only said to Tsukakoshi, "Don't hit."
Thereby, Weider (#1) lost 2 points. However, the "thorough fair play" is racing style of Honda.

About Weider (#1)
Although Duval's pace was good, since the tire was worn out, he did the early pit stop in 25laps. Pit stop time was 24 seconds. Pit crew worked well. Kogure's pace was also competitive in 2nd stints.
4th place at 88kg is splendid result.

About ARTA (#8)
Kobayashi took 6th position in qualifying. This is the top result of Honda teams. However, the steering trouble occurred in them in the race. We have to investigate the cause of this trouble.

About Nakajima (#32)
Michigami's pace did not increase according to the trouble mentioned above. However, since they extended Michigami's stint, they lost the opportunity to catch up with.

About Kunimitsu (#100)
They hovered at 15th position in qualifying. However, Yamamoto showed us wonderful driving and finished in the 5th place. His tire management was very good in very hard road condition.

I had ordered Duval and Kogure to finish the race ahead of a rival(#46).
They answered this order.

Welcome! Daverytimes

At first, it is technical regulations that unification is considered, it is not the series. Therefore, DTM is not held in Japan and SGT is not held in Germany. However, SGT cars may participate in DTM or DTM cars may participate in SGT.
The purpose of unification is cost reduction and standardization. "One car for multi series" is the purpose.
Second, the obstacle over regulation unification is because Japanese manufacturers' attitude is not decided. SGT is supported with three manufacturers' money. The series is not successful as business. The series is not sustainable if at least one of three companies is missing.
Therefore, in SGT, special consideration has been performed about the technical regulation among three companies (For example, HSV-010 of Honda does not have a base vehicle). However, this will become impossible if regulations are unified.

alexkiller8 · 20 Sep 2011, 11:16 (Ref:2958436)

in new dtm specs audi, bmw and mercedes share the same chassis and a lot of other parts (almost 70% of aero package) too. So i think that if a japanese automotive company is intersted in the dmt competition, saves more money building a new spec dtm car (building is maybe the wrong word, because to build there is only the engine and bodywork) and not converting a gt500 car in a dtm car.

TF110 · 20 Sep 2011, 17:10 (Ref:2958627)

I'd just want a race closer to home. It would be great to see them in DTM and DTM in SGT. I don't think it'll happen though.

**AUTOSPORT's SGT report

(About tire choice in Fuji round)
*Weider(#1) and KEIHIN(#17) used latest structual tires of BS. The concept of this tire is a tire which can run fast, even if weight is heavy.
The warm-up performance is also improving. However, Weider have not master the maximum performance of this tire yet.
*On the other hand, in Lexus, Tom's(#36) and LeMans(#6) used the 2010 version strucutal tire. (Tom's: Medium compound/ Medium, LeMans: Medium/ Hard) However, the rapid grip down happened to them.
ZENT CERUMO(#38) used the 2011 version structural tire.
Only CERUMO have managed the race in BS users of Lexus.
*Michelin also tried a new type tire in Fuji round, too.

Japanese Samurai · 24 Sep 2011, 09:50 (Ref:2960320)

(About 2012 regulations)
*As a principle, the newest BOP of FIA is applied to FIA-GT3 cars in 2012.
*The newest BOP is applied also to old FIA-GT3 cars.
*However, performance adjustment may be performed in plus-or-minus 10% of the BOP. This performance adjustment will be performed not by restrictor but by ballast, in order to balance FIA-GT3 and JAF-GT300.
Therefore, this performance adjustment will be performed not "by car" but "by category".

*The performance adjustment to old JAF-GT300 cars and FIA-GT2 cars had not been decided yet. However, it will not become performance equivalent to 2012 JAF-GT300 and FIA-GT3.
*Since the performance of GT300 car improves, the performance of JAF-GT500 car will improve, too. Restrictor size will be expanded by one rank and 50kg of minimum weight will become light.

Japanese Samurai · 24 Sep 2011, 09:51 (Ref:2960322)

(JAF-GT300 constructor's round-table talk)

*The price of JAF-GT300 Vemac (without engine) is 50 million yen.
*FIA-GT3 price list (1 euro = 106 yen)
Aston Martin DBRS9: 31,800,000 yen
AUDI R8LMS GT3: 31,590,000 yen
