Tks Gus
As support for Patrick

1 - By changing the excenters you will change quite a lot with the car. Setting them down will change the downstops and increase the time to run on a set of tires. Setting them backwards you will increase steering (on- and offpower). In general you just increase the downforce on your front tires by moving them more to the center of downforce of the car

2 - It will loosen a bit after some runs.

In general we (small tracks in Netherlands) do not have any problem with off-power steering. One other important point is that (combined with a lot of off-power steering) the rear-end should be on the edge of be´ng loose on-power.

Here a typical setup for a small track where there is a need for a lot of off-power steering:

http://www.team-shepherd.nl/images/s...%20NK4-MBC.pdf
thanks for the suggestions. i attached my setup.

you are using more front camber and caster, more reartoe and stiffer rear sway bar. you will notice i used only 1.5deg front camber, in the past with 2.0 i was getting coning on the front tires. but getting even wear may not be a good idea. (the tire wear is pretty high, so making the tires last longer is a good thing. this is the reason for the tightened corners. big sweepers eat tires faster)

can you tell me if 2 degrees toe out is total? (1 per side or is it 2 perside?)

Hello Tony,

Yes, its 2 degrees toe out in total. Some other suggestions:

I see that you run your P909 body on 18mm, you will get much more rear downforce than front (also poor corner entry is the result). This would explain your rear wear. We run between 22 - 24 mm, giving a better ballanced downforce. I also see that you are on +9mm downstps rear and 2 front, why? This would result in good corner entry handling but poor mid and exit. As last one, if you use CEFX option parts, use the rear

What is the ammount of piston holes fron and rear?

A lot of people like 18-20 but I'm with PM on this one:

Anything less than 22 for me and entry sucks. 24 seems the sweet spot for me.

It varies, depends on the body though most will be in the same ballpark.

What is the ammount of piston holes fron and rear?
i am using the stock pistons, 1 front, 2 rear. i am using all cefx parts, so i added 3mm to the caster setting. i have found that reduced droop made the car more responsive on turn in, or at least more predictable on turn in. as for body position i have a few usable bodies presently, a fwd and aft mounted version of the 909 and zytek; and a old kawahara (a favorite that i had a very good race day with in '08)

anyways, i have a second 909 which measures to 25.5mm. but my theory was that i wanted more rear downforce at speed to make up for increased steering at low speed. my intention was to get more low speed steering without sacrificing too much stability at higher speeds.

i will try getting things sorted with a looser body position. in the past with the 25mm body position, i was getting more rear tire wear with 38/38 and even wear with 38/40, but that was on a more open layout. this year with slower corners we are using using softer tires like 33/35 and i am still adjusting.

I will post a setup in 2 weeks from the track of Hildesheim (Germany) where we have the Euro's-B. Its a medium size track with lots of corners.

Hi guys any setup news from the Euros, I saw a V8 was on pole.

Quick question can the Serpent OS2 rims be used on the V8 or is it only kyosho/mugen ones that can be used?

OS2 IS the Kyosho/Mugen offset. The only difference is the little bevel on the backside. You can use them like they are, or you can get beveled spacers to put on the car if you wish.
