Top Racing HK Report from R35 Street Battle at ZIC in China

April 9, 2010 Comments off

The 27th and 28th of March was a big weekend for the GT-Rs around Hong Kong and China. For the first time ever, the R35 Street Battle was held at the Zhuhai International Circuit (ZIC) on the 29th and organized by the Hyper Zpeed Magazine. Many GT-Rs turned up for the event to see how fast they were able to go. Although there was a small drama on Saturday, one of the GT-Rs was severely damaged during practice, the race course was required to shut off for a while for clean up. It was a great day with nice sunshine, with an air temperature of 20 degrees and overall, it was proved to be an enjoyable event run smoothly.

Top Racing GT-R Professional Workshop also attended the event with their customers and became the spot light of the day. Since Top Racing had experience at Zhuhai International Circuit from previous trackdays, the track’s layout was well known to them. Since it was technically a Street Battle, Top Racing brought their street demo car up to ZIC to conduct the speed trial. This street spec car was able to manage a respectable 1:46.28 lap time and also set the highest top speed for the day of 244km/h at the end of the main straight. To top it off, on the very same night at the after battle dinner party, Top Racing GTR Professional Workshop won the Most Fashionable award, Quickest Lap Record award and the 2009 Media Best Tuner Gold award for their street demo car.

The Top Racing street demo car was equipped with the Willall Racing WR35MTT turbo setup which runs 1.1 bar of boost, HKS Hipermax III ZIC spec suspension, Tanabe sway bar, SSP radiator, Trust oil coolers for the engine and transmission, HKS Superior Spec R, Trust Intake Suction kit, HKS GT600 Kit, COBB Tuning AccessPORT, Dixcel R15 brake pads and SP FSC brake rotors. Also, in the transmission department it was equipped with the Dodson Motorsport mechanical circlips and FWD gear lock to ensure durability, as well as Willall Racing WR35CP clutch packs to ensure good bite while shifting gears.

What is special about this time out is a newly in-house designed aero kit which borrows concepts from the Nissan FIA GT1 spec race car. Not only does it give the GT-R a new aggressive look, but it could also decrease the engine oil, transmission oil and water temperature dramatically. This aero kit completely solves the usual temperature issues and allows the driver to drive their GT-R on the race track at full pace with peace of mind. The aero kit is made out of light weight, rigid dry carbon, and provides ducting to cool the front brakes down which helps solve the problem of brake over-heating. The new aero front bumper is also designed to give greater down-force and provide greater stability at high speed, add that to the fact that it reduces weight and you can see how it can improve handling. The kit reduces weight by 5kg in the hood, 5kg in the front bumper and under panels, 2.5kg in the rear bumper and 2.5kg in the rear trunk lid.

The Director of HKS product strategy management, Suguru Kobayashi, was also there on the day as a spectator, he was astonished with the cooling ability of this new aero kit and admired the quality and design. He is greatly interested in the aero kit, and in discussions with Top Racing, has requested a set for testing on the HKS R35 demo car.

Unfortunately, Top Racing’s race ready R35 “TR35” was unable to attend this event. The TR35 GT-R features an even more aggressive aero kit which provides for even wider front wheels. We are all anxious to see how well the TR35 will perform with the wide body kit on the race track.

So it was an enjoyable weekend at ZIC, everyone from Top Racing and their clients had fun and enjoyed the thrill of high speed on the race track, they are all looking forward to hitting the track again very soon.

Top Racing Hong Kong would like to take this opportunity to give a special thanks to the following:

  • Weave Carbon Series
  • HKS
  • Dodson Motorsport
  • TANABE Japan
  • Willall Racing
  • TOYO

Top Racing HK: Track Day Performance at ZIC in China

October 27, 2009 Comments off


A little over a month back now, Hong Kong based tuner Top Racing was out at Zhuihai International Circuit in China to collect data on the Willall Racing cooling solutions and the HKS suspension systems for the Nissan GT-R. This particular R35 Demo car was built aiming to set as a reference for other R35 owners.

The Top Racing GT-R Demo car is fitted with what some would term as only mild, bolt on modifications. We see the HKS GT600 Kit with the HKS Superior Spec R Titan Muffler, the latest HKS Hypermax 3 Super Sport Suspension, COBB Tuning Anti-roll Bar, COBB Tuning AccessPORT, Willall Transmission Cooler and Dixcel RE Brake Pads with rotors.


Over the course of the two day track event, the air temperature was close to 40 degrees celsius. Top Racing conducted the tests with the GT-R tuned to run 1.1 bar of boost with Willall Racing oils protecting the engine, transmission and the differentials. Saturday’s main focus was on the suspension setting and after all was said and done the guys managed a best time of 1:47.6.

On Sunday, there was a chance for the Top Racing team to stress test the oil and the cooling system. During testing their results were pointing in the right direction but, due to interruptions, only 8 hot laps were able to be completed during the one session. Based on the data gathered however, there is no doubt that the oil will maintain good temperatures even over a 10 lap session in the scorching heat.

Overall, it was a successful event, and the data gathered by the Top Racing Demo car will be extremely useful to use as a baseline for further GT-R builds to come. Taking certain steps with the setup of the car can go a long way to eliminating any over heating issues.

Furthermore, another point worth making was in regards to the Dixcel RE brake pads. Their performance overall was extremely good with no sight of fading even after 8 laps back to back in the heat. Moreover, the wear on the brake discs and the pads over the two days was far less than expected. These brake pads were developed for endurance races, and are highly recommended for GT-R users planning to do some track work.

Next steps for Top Racing are to look forward to building a more aggressive track orientated R35 GT-R with a horsepower target of between 700 ~ 800 hp. The guys are looking forward to an even better laptime next visit to Zhuihai.
