At shocks removed plactic spacer between o-rings to make shocks more free.
Shock oils where 600cst/400cst, diff oils 20k/1M/10k
Ride height 16mm front and 17mm rear

Car was very easy to drive, I`m not a pro driver, so I managed to flip it over several times, but I have never so many times cached the car when it trys to flip over...run on two wheels for a time and then sattle it back to all four...I have seen how pro`s do it... I thought that is impossible...mega skills necessary, but now with this car I can also be like a pro

This firs practice day I enjoyed and just drived, not experimented with setup, but still some things where need improvements:
1. Car was a bit understeer, any ideas how to reduce it?
2. The same as others said, car squats a little to much, and it probably makes understeer...
3. Stock wing... could it be a reason for understeer, as its with high downforce.. which other wing you can advice?
4. For our track also my shock setup seemd to be a bit to stiff/hard, because on to pass small edgy rams the car feels very stiff... I plan to change oils to a bit lighter...actualy I dont know when springs and when oils must be changed to lighter or to stiffer... so here also some advice necessary

Above you said that longer wheel base could help to avoid squating, so some mm of rear arms are removed- do you remove those mm just at inside hinge pin, or also at outside?

Hi hardijs, I think the 1 Million in the centre is to heavy, try coming down to 200k. Also try coming down on shock oil's to 300cst rear / 500cst front, Run the shocks in the outer hole on the arms. I would keep the heavier springs on, especially on the rear. Keep the pistons as 1.5 all round, running a bigger hole rear piston will give more steering and a little better straight line bump handling, but it will also make the car want to squat even more! Your ride height looks ok. after making the changes, and if you still need more steering, come down to 10k in the front diff.

The rear arms, your taking the 2mm away from the inner pin side, as per my photo above.

Hope this is of some help, let us know how you get on.
