I made a cut to the chassis to get some rear flex today and managed to test it. It made a huge improvement on the on power out of corners problem that I had (at least it worked at my local track). I can drive it hard out of tight corners comfortably now. I m getting to love this car. Next test will be on mid day where the track temp is higher (simulating race condition) and hopefully it will work the same as I tested it this evening when the temp was cooler. I m super happy now.
I can post a pic if anybody wants to see the mod I made.
