Finally got the car ready to run for the first event of 2019. Aside from the rear diff, the car’s had some minor tweaks to its setup that overall should not really impact the handling.
Overall though, I was underwhelmed by the OS Giken 1.5-way. The manufacturers make a lot of claims about what this diff can do, but ultimately when the rubber met the road, it did not feel significantly different from the Cusco. I was expecting the car to be significantly looser off throttle, and in the end I couldn’t really tell much difference off throttle, which is their “special sauce” with the negative preload springs. On throttle, i noticed that the diff was definitely not locking as hard. No power oversteer to be found here. I need a few more events to get a better feel of what the diff and the car is doing, but in the end it wasn’t as aggressive as I was hoping it to be.
Driving wasn’t spot on this event, I’ve got a lot of rust to get off.
Things to work on (Evo):
- Drive smoother, better lines and closer to cones
- Carry more speed into slaloms & maintain speed vs on/off throttle
- 1/4 tank
- Camber at -3.2, -1.8 rear, 0 toe front 0 toe rear
- 35psi all around (RT615k+)
- ACD (Aggressive): Tarmac, Dampers 5/5 F/R, RSB on soft
- Girodisc S/S pads front and rear
- 2019 Runs (6 on Evo, 43 runs on RT615k+)
2019 Run Count: 6 (+6 Evo)
