Weight, Aero, Brakes, Power & More


The off-season is in full swing, and although I feel like we are ahead of schedule, we will still inevitably work down to the wire in the effort to get the large off-season check list done in time to test at VIR at the end of March. This off-season we aren’t doing anything too crazy, but finally finishing the long list of items on the car that never seemed to get done and were always at the back of the essential list. This off season was about attention to detail, and getting out as much weight as possible.

The most time consuming items so far have been the weight cutting. The G35 is easily the heaviest car in the Limited RWD class every weekend and its about time I do what I can to limit that, unfortunately the car can only cut weight in so many places.

After more hours than id like to admit I think I have finally cut everything out that I can at the time of this post, but I still have a few more places I may look at. So far I would guess in material alone we have taken out a solid 70-90lbs, which is a bit more than I was expecting without going too insane.

After the weight reduction, the biggest off season task is re-creating a much more efficient rear diffuser and a large front splitter with a bumper lip. So far we have mocked up the new splitter and diffuser in cardboard and wood and are getting close to cutting and fabricating the rear diffuser in the coming weeks. The design should end up looking amazing and will end up as a floating diffuser design similar to the Corvette GT3 cars or the Ford GT GT3’s. I can wait to post final photos and test on track in a few months.

We installed new Stoptech Aeroslot Rotors, new G-Loc Brake Pads R12 Fronts / R10 Rear’s, flushed all of the fluid and replaced it with new Motul RBF 660.

Many people didn’t know but for the entire second half of the 2016 season we were down on power due to maxing out our fuel system after the motor rebuild and new higher octane fuel supplied by Ignite Racing Fuel. I can’t wait to get the weight off, new aero on and a a new race tune with more power! Until then be sure to follow on Instagram and Facebook for more up to date progress on the #44 BC Racing Time Attack G35 in preparation for the 2017 season.
