yeah this is a really tough car on this track. You have to be real relaxed on the throttle and steering check out my replay if you want to get an idea of how I run.
I also changed my sound settings to help me coupe with oversteer and loss of grip. I set tires to be the primary sound and removed music.
When I start hearing tires squeal I try to straighten out my steering and/or let of the gas slightly (it's all about being smooth if you go off the track all you have to do is run another lap. You make more money anyway doing more laps

) so I still have traction and therefore am increasing my speed instead of decreasing it. I'm currently 3 seconds slower than the top guys still but I'm improving
