RedOak,
The biggest problem with using a ghost is that you tend to follow the ghost rather than create a new lap.
This means you repeat the same mistakes made in the ghost replay and because of that you will never go any faster than the ghost.
My suggestion for dealing with this...
Run a slow but clean lap.
Use that as your ghost for a few attempts, then turn off the ghost and try again without it.
Doing that will give you the chance to have a ghost and in those first couple of tries, learn where it is slowest.
Then if you don't beat the ghost, turning it off will give you the chance to race past it without realizing it.
Just remember to take it easy on your first lap.
Nothing is harder than setting a best lap without ever getting a clean lap first.
Once you have a clean lap, especially if it is slow, you will be able to see where you can push for gains and where you can naturally cruise the course without lossing time.
I know it sounds rediculus for me to say "get a slow time first" but trust me, nothing will help you to improve you own time like finding out how fast or slow it is on your own. 👍
So just to recap...
Run a slow, clean lap.
Run against the ghost for maybe 2 laps.
Run without the ghost for as long as you can bear it.
Turn the ghost back on and try to learn where the mistakes are.
Keep working on it like this and before you know it, you will have a lap that is clean and refined to the point of having very few errors.
Good luck and let all of us know how it goes.
Also, if your rear end is sliding out too much, don't be scared to use TCS... There is nothing wrong with a little tcs if it makes you faster. 👍
