    Here you will find tips on the driving and tuning side of GT. This was started for GT5P and most will carry over to GT5. This thread will also be used for the driving school that is in the works, and yes, there will be a test.:sFun_nahnahna:
    Once GT5 comes out, updates will be added.

    I found out that some cars can hide thier true set up problems. The perfect example of this is the Cappi with the RM. When you first take it out for a test run. The back end stepps out and you think, "Wow, dose this thing have wild overstear." So you start to tune it to correct the problem. you seem to be getting it fixed, but it still will snap the back out from time to time. And a push seems to have started. Now what do you do? First off, make a room in your "lobby" that meets the race regs. Set it up for 5 - 10 laps. Now start the race with just you in it. After the race, watch the replay and pay close attention to your tires. They will give you hints as to what is going on. With the Cappi, the fronts would gain temp as you ran because the push or tight condition is causing the fronts to over work. Once they hit the right temp, they will gain grip and will turn the car sharply. This in turn will cause the rear to snap around and off the track you go. So what dose this tell us? Well it seems that the car had this problem from the start but was missed because it was acting like it had another problem. So we need to start the tuning over. This time we need to correct the push condition. Yes, I know that you can't feel it but trust me, it's there. As you work on the tune you will find that hte car will start to handle better. This tells you that you are on the right track and to keep going. You will know if you have gone too far. Always do your tuning in your lobby and not in the practice mode. The set ups will give you a false reading on how your car is doing.

    :sSc_eek: I didn't realize that it has been this long since I last posted here. Well time to fix that.

    Over the past while, some of us have found little things that make things a little easier on the tuning side. Some of you might have already figured things out, most have not. So here we go.........

    1) Trust the stock tune! Except the rear toe setting, the stock tune is a good place to start.
    2) Race tires need harder springs! The stock springs work well on sport tires, but are way too soft for race tires.
    3) Use the ballast guide to help with your choice in settings! A car with a ballast split of 40% front and 60% rear will need a stronger rear spring. Lets say the stock spring settings are 6.5 front and 8.8 rear. Put racing soft on and take it out onto the track. you will find that the car will act like it has a big case of over steer. Now, with the old game engine from GT5P, we would switch the springs around to cure the problem. THIS WILL NOT WORK IN GT5!!!! Well, 90% of the time it will not.( Some cars just have to go against the grain) The proper thing to do is to keep the stock "split" of the spring, and make them stronger. Remember the stock springs? The split was 2.3, so now we will stiffen things up. Add 5.0 to both ends. You will now be at 11.5/ 13.8 Return to the track and see what happens. Are you surprised? You will be. What I just described is what I did to the RUF BTR, I shaved off over 4 secs on my lap time at LeSarth. AND THAT IS ALL I DID! (rear toe was 0.00/+0.02) With rear areo, the car became even more stable.
    Don't be scared to try things that just make no sense. you just might be surprised on what you will find.:sHa_clap:

    OK, it's been about 3 months since my last post here, sorry for the dalays but RL just keeps getting in the way. But I'm have some time and here we go.
    We have had a big influx of new drivers here at the TPRA. So :welcome::welcomeCCC: Some of you have driving skills and some are still learning. For the learning group of you, here are some things you can do to help improve. The main thing most need to learn is car control. It's easy to run fast, but if you lose it in the turns, you a) lose time and b) make friends with the MARSHALLS. One of the best way to learn car control is this. Get a Shellby COBRA. Put Race soft tires on. Go to your lounge and load up Laguna Seca and set the track to REAL traction, assists set to off, (ABS set to 1) and "No Tuning" Tire wear on. Now head out and run some laps. Once you get use to the car you should be turning laps at 1:30's Now put on Race Medium and repeat. Lap time should be around 1:33's Doing this helps you find your braking points and throttle control as you exit the turns. Now the next step will be getting use to running in a pack with others. This we will do in the near future.
