First outing with my cars this weekend. 17.5 was hooked up but I stripped two Spurs in the first two laps so that car was done for the day. I had xenon Spurs that I think were to soft for this car. On my usgt I had a arc spur and it held up. Had a hard time getting it dialed. Same setup at first as my 17.5 but had to drop the shocks all the way down in rear to get any kind of traction. I didn't get enough real practice in to try any other changes. I was thinking I needed to change diff oil from the 2k I had in it to maybe 1k. That might of got the rear from coming around to much in corners. Other than that I liked the way they felt. Lots of steering.
