I've found a higher roll center will give less grip on that end of the car. If you're raising the rear 2mm higher than stock, you're way too high. I usually run mine with the stock plate in the rear and only 1mm shims in the front. I like lower roll centers. Longer wheel base in the rear seems to smooth the car out and make it easier to drive. I'll usually leave it in the middle and if the car is fast but sketchy, I'll lengthen it to fine tune it.

An old teamdriver of Schumacher "Niels Koenekoop" gave me his setup and that was also with 2mm extra roll centre. that's why i tried it.
Indoors it worked well.
But since a month or 2 Niels is not a teamdriver anymore so there are no reral good drivers with an MI2 in holland any more.

What i also thougt about is what do you guys do with droop.
Do you run low droop or high droop.

i ran now fron 6.5mm rear 7.5mm(up travel from ride hight)

in generaly the more droop the more grip or?

Thanks,

Indoor carpet setups are Greek to me. I'm not sure if they prefer high roll centers on those setups or not. (I guess I should learn them since I'm going to the Vegas race )

An additional 6.5mm from ride height! That's a lot. I run 2.5mm in the front and 3mm in the rear. The more droop, the more weight can transfer to the opposite side. Too much rear droop will let the car transfer too much weight forward and make the rear too light off power.

Arjen

Ok so that could be also a bit of the problem.
Tomorrow I will build my car up again and i will make a lot of changes like u told to me and i hope that i have time at the end of the week to test it.

Yes it could. Tell you what, give me your Email and I'll send you a good outdoor asphalt setup. Do you have Excell on your PC?

I would maybe try the rear shock mounted one hole further in on the wishbone and the mount. Where you are running with the spring that you are using is quite stiff overall. In that hole i used to use an associated silver, and often a silver with it mounted one in if traction was real low.

Try 1mm more droop all round. Should give a little more grip.

Didn't know Neils had made the change

xcel/word/acrobat.

What i most of the time do is make an setup in acrobat.
then click on the camera and select it en past it in word so you can save it.

Really thanks for your help.

Actually didn't read that droop setting properly, if that is over ride height then it is too much. Jon''s suggestion is about right.

Arjen

Niels stopped with driving much. only sometimes for fun.

I have ordered athe AE spring set so i can test a bit moer springs because i thing xray and AE combined isn't that good.


Droop:
Yes it was an 7.5mm additional to the ride height.
so i will change that.

John, if you want that setup put on a .pdf setup sheet, send it to me and I'll do it for you. [email protected]

Arjen....Matt is correct about the shock position on the lower rear arm. That and the droop are the 2 major things I see wrong.

I've got my own setup sheet I made up It's pretty dialed. A lot more detail and it's really easy for me. I have every setup sheet on my hard drive from the last 3 years. I'll send the blank to you. I know Donny liked it a lot.

Arjen

I would like to thank you all for your help with the setup.
I have now a lot of things to test and i will lett you know how it went.
