Something I experienced and have noticed with others is that with the Ck, newer racers seem to have about 5 good minutes and then start struggling with the car getting loose, those that run the T-Fouce have not had this problem.
I am still fairly new to the 12th scale scene as this is my second year of racing it indoors on carpet, but I feel like the T-Fource has been easier for me to run from one week to the next without the issue mentioned above.
I don't know why some of the guys have this problem or what the cause is, but for me, switching to a T bar car has helped a lot. At some point I would like to get a link car again and see how i do as my drving has improved quite a bit over the last year.
