Need carpet setup X10

[frode]

I need a carpet setup. I have used the setup that comes with the car kit, but the car is flipping over too fast in corners. The grip is very good.
Any suggestions?

I used the following:-

35wt oil in the front with the valve
55wt oil in the rear
yellow schumacher minispins on the rear
yellow schumacher minispikes (2wd) on the front

anti-roll bars all round, mounted on the "short" hole (the one closest to the car)

ran the car with about 20mm ground clearance

BUT I ran cut down front wheels with 2wd minispikes on them....it was a bit under-steery at slow speeds, but was fine at high speed. (I think that is more of a factor of the carpet though rather than the setup).

so you mounted them on the outside, didn't stretched them open ? (like you do with slim tires, stagger rib, on B4 front wheels)

Try less caster on the front which will make the turn in less harsh.

I actually cut the inside edge of the wheel off, level with what was the middle rib of the wheel, therefore running "narrow" wheels.

going to try that one out on my hometrack, I still have to much steering ...

You may also want to try cut/shut (narrowed down) mini spikes on the front, that way you keep the same radius with less width. We used that off road on astroturf a lot.

We also had a small set of end cutter to take the outer and inner row of spikes off the tyres, this helped as well.

I'm going to try 2wd minipins on the front at our next regional which is Astroturf indoors!

let me know how it went, I think that is the thing to have for astroturf, maybe front wheels on the back.

[Northy]

I'll give it a try, but not sure about the front wheels on the back Coop, have you tried it?

[Cooper]

no but i've read something about someone who did (here somewhere?) , and on my track some people do it (no preds but other 4wd cars))

what do you mean by "the valve"
I ran this set up at maritime last night and had major grip roll
in hair pins when the tyres warmed up, sweepers where no problem, would thicker front shock oil be a better bet ??

What you have to consider Geoff, the carpet grade on which Chris raced on maybe less grip than the carpet you raced at the maritime, some things i would do. Put a thicker oil (as you suggested) in the fronts, perhaps 45 - 55.

Secondly, i would trim the 2 outside row of spikes on the rear tyres, and all the outside rows on the fronts with every other on the second row, if you get what i mean?.

If its still rolling, then take off the rear anti roll bar and perhaps put in harder spring on the fronts, that should tame it.

Or perhaps you can try something before all that up top and just put in some half worn tyres, GL.
