I test at Circuito de la Sierra because it has a good mix of everything from high and low speed turns, jumps and small sideway jumps, high speed strights, chicanes and not much room for errors. 500PP is my favorite class and thats where my focus on tuning is right now using Production Cars only on Sport Soft tires with a controller and Automatic Transmission. The brake system in this car is sub par at best so my focus was getting the most out of mid corner and corner exit speed since you can't rush into corners with this car. I will try to explain the madness behind my tune for the Nissan Fairlady Z 300ZX TwinTurbo (z32) '89 at Circuito de la Sierra. This track possess all kinds of challenges mixed in one bag and car setups will be different here than a smooth race track. The car is definitely not one sought after in online racing or anywhere for that matter. Like most of the 80's cars in GT6 they just don't handle well and are hard to tune. Lets face it there are just mutch better handle cars in GT6 that make people skip over cars like this....plus Im a huge fan of 60's 70's 80's cars in the game and its a real challenge to tune some of them. 1. First I set my Ride Hight and Springs for a smooth ride across rumble strips and airborne jumps keeping the car settled on the ground and in the air. Once this is the achieve everything eles is all about maximum traction and my adjustments to the Damper Compression Rear, Dampers Extension Front are a reflection of that. 2. Next I moved on to the Toe angles. My Rear Toe angle was set positive for turn in and straight line grip of the rear tires and the Front Toe was set negative for slight oversteer and front end turn in grip. 3. Next is the Camber and it can be tricky to set up at this track because of its many different challenges. The more Rear Camber thats added the less grip you have on a Rear Wheels and that is almost always a bad thing so finding that balance is not an easy task and why I have more camber added here than I would run on a race track. Example: take a look at the video below ( between 1:10 to 1:20 ) at first your car goes airborne over the hill then the road quickly turns left so at this point you must place your car all the way over to the left with two tires over the rumble strip as the car loses all the weight on its suspension and in some cases is airborne again in a downhill curve. If you're carrying any kind of speed when the car lands and the Camber angles Front and Rear are set to low the car will immediately start sliding until its off the road into the dirt and slams into the guardrail. If you have the Front Camber angle set to lets say 1.0 and very little to no Camber angle set on the Rear lets say between 0.0 and 0.5 then the cars Front will grab traction but the Rear will slide causing the car to start violently fishtailing or spin out of control immediately. By having both Front and Rear Camber angles set to 1.0 or higher the car then has enough grip to put the power down when the car lands even though all its weight transferred to the right side. The trade off is some rear wheel spin coming out of sharp low speed corners even with the LSD set very low. 4.The 300ZX is not happy on late braking as its Brake System is sub par at best so you must scrub off alot of speed before you reach the corner and make your time back up putting the power back down mid corner through the corner exit. I also used some ballast here to keep the Front and Rear tires from glowing red so much. I also now run +2 wheels when its aloud for more grip. So that's a little run down on my tuning madness and I would really appreciate it if you two could look at it sometime and let me know what I've done right and what I need to improve and work on. Im really enjoying the tuning aspect of GT6 and I'm very eager to learn more. [MEDIA=youtube]BENK7xwsYWA[/MEDIA] [/QUOTE]
