so in reality a lower roll center would help on traction if you had a loose car in the rear?? am i thinking right??

i understand... thanks for explaining it more..

Yea raising the pins will give you more side bite at that end of the car while on rubber tires.

Well the main reason i asked about the roll center is that i do run on rubber tires , from what i read Manufactures like xray and assocaited both claim that a high roll center decreases traction, maybe i read it wrong don't know, so i wanted to find out for sure..

Keep in mind that the roll center is not only adjusted by the pin height, that is only one aspect so you can't really compare.

It doesn't really matter though. Just set the front high and adjust the rear to you liking.

My car is loose in and loose out. Seems to be ok through the center, maybe a little tight. Right now I have Losi 30 with 17.5 springs in front and Losi 20 with 10.5 springs in rear. No sway bars. Maybe I have the car rolling too much?
I did drive someone elses car the other night. It is a Phi and it was stuck. I could not get it to break loose and I was a half second faster with it.

You can also try running the top deck with orings under the 4 center screws, this will give a some more flex and may give you some more grip.

I would start with 15lb springs in the rear, there is such as thing as too soft, and underdampened. I drove a friends car that he had put together (his first rc kit build) and I neglected to go over his shocks, but had made sure the rest of the car was ok, it was on ice skates on 3 different sets of tires. Another racer came by and pushed on the front of the car and it was really light since he didn't build the shocks right, we re filled them with oil and bled them properly and the car was much much better. I only use this as an example that softer isn't always better, its a bit extreme.

Agreed, just wanted to add, make sure you don't have too much oil in the shocks. The rebound should be slow and smootha and only about 50% of the shock length. If you have too much oil it will make the car twitchy and erratic and it won't matter what oil weight it is. The car will just do weird stuff all over the place.

What effect does diff height do? I've never had the option on previous cars, so I don't know anything about diff height through experience.

for flowing tracks with sweepers i set the rear at low setting, it should handle the long turns much better BUt if you want to free up the car then put the rear diff at the high position which is more suitable for small tracks
I am very sure that all of this is in the manual.
