Sorry to hear that fellas, but let me tell you what you already know.
Practice is the only way to get around the problems you're having.
I am "good" on rome II thanks to sough running a "purchasable car @ rome II" race. (forget the name)
Spent a ton of time for about a solid week's worth of racing. Did alright in the results, but it was later on when I went back to rome II that I noticed the difference.
Now I can lap pretty clean for most laps... it's really just a matter of getting a t1 I will accept (or beating a ghost to t1), if I can do those, then I am good for the lap. (most of the time)
Then again, the section following the t1 straight also manages to take its toll... hence, I don't really get to make as many clean laps as it would sound based on what I said above.
I gotta ask, are you guys having road or race troubles?
You may wanna just take a break and move onto the other division, then again, you may want to just concentrate on one category.
I think what I will be doing is running a bad road lap just to submit one, and a real attempt at a race lap.
Anyway, gotta run, getting ready for school.
