Thanks for this. It does look very similar to the stock setup though, in any case I'll give it a try!

Maybe loosen the sway bar (goto 0.04) and perhaps stiffen up the rears. Another 0.5-1mm in rear drop may not hurt either.

you could also go back to the stock 3 mm rear toe, as well as perhaps lengthening the rear camber link.

That setup is very close to what i run at BCR and Camarillo but i have 3degrees toe in the rear and no anti/pro squat, i run it level. and i have .030 kickup and no sway bars when im at bending Corners

Looking at Metalracer2's setup a few posts up, what changes would people make to get the car to work on dusty carpet with very low traction?

3 dg rear toe, 2 dg camber all around, .040 rear sway bar, 2 dg caster blocks if you need steering. How is your carpet dusty? do you run traction compound on the tires?

There is both a dirt track and a carpet track in the same building. There is a wall between the dirt and carpet, but the track is still dusty after an off-road race. After some cars get on the track, they dust gets moved out of the grove, but it is still low traction.

So, you would not go softer on the springs/oil?

I use paragon.

Thanks

that's gotta be a unique track. It might take some out of the norm setups for you to get what you need. Lighter springs and oils are going to allow more roll, but it can be too much, unless your car feels like it's on ice skates, I would tune things slowly and one change at a time.

How does car feel with what you have on the car now, how is it compared to other brand cars?

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.

got a question about roll center??? does a high roll center provide you with more traction or less, or does a low roll center provide you with more grip??? losi manuals say that a high roll center gets more grip, but seen some other reliable manufactures say the opposite, that a low roll center gives you more grip??? just want a clarification, i know it probably depends on setup, but just in general.

thanks for the help

Think about what the car is doing... A higher roll center puts more weight on the tire. A lower roll center put less weight on a tire.
