I suppose it depends on what Springs you are using, what tyres and what grade shock oil. I'm using 25 weight oil (Associated) and the SS Purple Springs that came with it. I generally race on grass and so far I've only run the kit tyres. To my suprise, they seem to work really well - but I'm comparing my Truck's overall performance to a whole bunch of Tmaxxs that keep having a bad day when I'm around

Now I'd like to try those anti roll bars/sway bars, based on Nitrohead's recommendations. To be honest, I'm not having any problems with grip roll, but would like to see how running one on the rear would help the steering response.

BTW, glad your truck is running good!
