I did indeed utilize the Calsonic to a great degree in the
Laguna Seca Enduro and the
Grand Valley Enduro. Both include settings, and best lap times, as well as multiple indepth notes. Big Blue ran beautifully. i didn't have too much of a problem, very smooth and stable through turns, and even over the corkscrew.
You said you're having a problem with it sliding all over the track...Which menas you're likely braking too hard and too late coming into corners. As another note, I'm betting, you can't keep the back end planted when accelerating out of corners? Tends to fishtail out alot? This means one of two things, you've got way too much power (easy mistake with any skyline), and you're punching the power too fast coming out of the corner.
I know you've already finished the race, but do any of the reactions sound familiar? Please remember these are only suggestions, but give this a try...Add all the mods
except the turbos, put super slicks on it, and run 10 laps around Grand Valley in the Arcade mode. Simply Bottom out the suspension, adjust the final drive to 4.500, and set the Auto Level at a level where you'll hit the redline at the end of front straight. Boost teh brakes to 17 front/15 rear. Boost your downforce as high as it goes. set ASM at 0, and TCS at 1. Leave everything else the same.
As two notes that I found
really helped, learn to use the analog sticks. Right one is Gas & Brake, left one is Steering. And don't "slam" the throttle.
Does the car react the way it used to? As a bit of homework, can you tell me the change in car reaction, and why you think the changes happened?
Hope this helps, and keep us posted about the rest of the story.
