Info on the car

HowYOU drive the car determines how the CAR HANDLES FOR YOU. What made me said this is how people would use a setup such as this as a base tune for them without trying the car while it is stock. Just experiment with the car till you find a balance that works and then accept the critique from others online about your setup in order to make it better. With that said let us break down the setup of this car.
The first thing I had people (my friends from college) ask me was why did you max out the horsepower of the car but de-tuned it to 602 HP @ 84.6 percent? I did this because I was entering online lobbies that were hosting Super GT500 events set at 610hp and 631pp. So yes this is an online racing tune. It is true the more hp the better but keep in mind that your transmission must agree with that power as well on various tracks. So in my mind a 602 hp car with a top speed set at 183 seemed balance for tracks such as Nurburgring GP, Twin Ring Road Course, and other medium tracks while 211 seem fitting for tracks like Autodromo, Daytona, and Spa just to name a few. The key shifting points are in-between the revs of 6000-7500rpm.
Another question people were asking me was why didn't you mess with the LSD? Tuning LSD without know what it does can be very risky since tuning it could have a chance of making the car better or have the horrible effect of destroying the overall balance of the car despite how well you tune your suspension. In my case, I felt that messing with the LSD wasn't necessary since it felt balance before and after the tune. So it wasn't worth gambling the balance of this car on the LSD. You will also notice that the spring rates are stiffer in the front. Keep this in mind a slightly under-steering car is 9/10 times faster than an over-steering car. This car was tuned to have some under-steer at speed but will face oversteer if you try to floor it around the apex of a tight turn (some people think that such a car exist when in reality it doesn't). The overall setup of the suspension is for the car to be a little on the under-steering side, it has the over-steer characteristic down. As far as wheel alignment, it was tuned to have maximum tire life without giving up the overall handling of the car. Running a 10 lap online race on Motegi Road Course, soft tires ran for 7 out of the 10 laps of the race scoring a 1st place victory against 5 others.
So as a last bit of information, it really comes down to preference to this car. We as tuners should know there is no perfect setup and we normally tune it to our liking which may or may not help others. As usual, try out the car and this setup 1st and then tune the car to your liking. Feedback (good or bad) is always welcomed but please do not turn this into a 'mine is better than yours' competition. Have fun.
