Marc and I looked shared setup info, but we both did our own thing. The main difference was in the springs and the diff oil. He ran yokomo springs and I ran serpent springs, but the springs felt very close given that I ran my rear shocks on the inner hole of the arm. I ended up using grey springs all around, while marc I think had yokomo pink and blue. His springs felt more linear while mine felt a little more progressive.

In terms of the diff oil, I ran 1000w and I think he ended up somewhere around 2000w.

oh yeah...he also ran 2.5 rear toe where I ran 3.0. I tried the 2.5, but with my diff oil being much lighter than his it gave the car too much off power steering.

I ran 5mm inboard spacers on the upper links. On the rear upper links I rn 4mm inboard and 3mm outboard. I think Marc ran about the same if not exactly that.

We both ran 0.5 mm spacers under the hinge pin blocks.

we both ran a spool.

Marc's car was traction rolling initially as he had the shocks layed down more than mine, but after he changed to using the 4 position in the rear and 3 in the front like mine, he stopped traction rolling.

With the exception of Alexander and Nayoto, we all ran 10.3 s laps as our fast laps in mod. Alexander and Nayato fast laps were 10.1. So it was good tight competition for positions 3 through 10 in the a main, determined by consistency instead of outright pace.

During the main, our opening lap was very clean until the last corner of the first lap where about 5 cars got together in a chain reaction. Unfortunately I got flipped by a car behind me and went to last place. I ended up 7th and marc ended up 4th.

Martin, can you tell me if it's possible to change away a car rotates by changing the rear gear diff lube cst or weight?

thicker oil will give you less off power steering and more on-power steering.
thinner oil will give you more off power steering and less on-power steering.

what are your suggestion in what order you should set up your car?
like 1.Downstop 2. Ride height 3. Camber etc...

This is a great and important question.

1) I make sure the chassis is flat on a setup board without any tires on it. if not, loosen screws give the chassis a couple of twists and the put back on the board...tighten the screws. the order you tighten the screws is important. Start with the screws holding the bulk heads to the chassis first then do the upper deck, then do the screws holding the top portion of the bulk heads to the bottom portion of the bulk heads...then do the screws holding the shock tower to the upper portion of the bulk heads.

2) then ride height
3) then droop.
4) then make sure the spring preload is balacned left and right.
5) the recheck droop and ride hight to make sure nothing changed.
6) camber
