I found the durango to be even worse outdoors, specially on very bumpy tracks, we just couldn't get the car settled and a lot of people had the same problem at the end of season finals last year. To calm the durango down a little indoor on hi grip we went to the extremes of putting 1000wt in the rear diffs and 3000wt in the front, it worked! was a lot easier to drive and get the power down. The Durango is like marmite, you either love it or you dont
but like i said in an earlier post, im not slagging the car off it's just personal preference
On the durango I used the serrated nylon wheel nuts, there were adequately tightened, and i tightened them before each run, there has been a lot of topics started about this and quiet a lot of people it has happened to. We even started putting a blob of thread lock on there, and it still managed to work its way off during the players. You don't have to replace wheel nuts all the time with the CAT, or most other cars infact.
