need help with truck setup

[ajdj]

SteveI need help. I raced my rustler for the first time and had problem with the truck not grabbing in the turns. The track is a oval track with left hand turns. I tried with no spprings on the left side like some were using but didnt work so I tried shimming the right front side but that didnt work. The truck pushes in the turn and the left rear tire comes up in the turns, I even tried to lower it some in the back but then it was to low. But the best thing is that I did win the finals,I beat two guys with gts and two guys with rustlers. The one guy with the gt was hooking up good but had motor problems in the finals,the other was hooking up not bad and running fast but got in some wrecks and had to pit a few times so my not so good traction won but will not the next time in a 50 lap race. the next guy had 28 or 30 laps when I won. Please help. I could use some tips on some tires to use also and some silicone that works goon on street tires since no foams are available yet for the rusler.
Thanks
