Ran a shorty lipo for the first time in stock 2 wheel yesterday. I ran on a small indoor clay track with medium traction. I really liked the way the car rotates with the shorty and how nimble it felt in the turns. Pretty much just ran it even with the u-brace,added 1 ball stud washer on the inner link all the way around,and switched from black to brown springs in the front. I have a little more fine tuning to do but its definitley a great option. Gonna try it on a larger track this weekend with a little better traction. I may try one in stock sc and truck as well.
