I found a setup I manage to translate in English in some way. However, there is still some information I can get such as front swaybar, front & side springs.

So I looking for someone with some more knowledge in Japanese that can give a hand for those details. Anyone?
Here is the setup sheet.

Having problems with toe in..

Turn the steering completely to the right or left pushing up the front arms the wheel no matter what I do always has toe in..

This seems to be something which appears with the lower arm are attached to the front shocks is there something which I am missing???

Second Question..

Anyone worked out what effect the droop has on the car??

It would seem droop + front shock + lower arm + anti roll bars all effect each other..

Anyone able to shed ligt on the effects of each...

Hi m8, on the first question, no idea what you mean. I tried doing the same as you but as far as I see the toe angle keeps toe- out when steering and compressing the suspension.
But I hardly think you will steer that much, if you are you need a lot more steering in your car, I usually have a steering circle of about 1.2m.

2nd question:
I almost have 0 droop on the yokomo front (and thats the way I like it), I suspect the droop on this front end will do the same as droop on the other front ends.
The more droop you have the more steering you loose when accelerating because the suspension can lift more.

Anyway, I'll be trying out the car for the first time today. I've glued up a whole lot of tires a few days ago and I hope to find a working combo.
I'm putting my hopes on the soft rears (seems to be magenta-like) and the medium fronts (also in the magenta-purple range).

Are you describing bump-in. Basically when the car is at rest and you are looking at it from above the tires are straight, then you compress the front end downward and the tires then toe-in?

R12 must be the best 12th on the market..

finally got time to test

running

800 - front shock
500 - center shock
350 - center side shock

Gold center spring

no springs on the front shock, and silver front arm spring (kit)

Tire super grip rear hard front all Yokomo, Glue them yourself makes for such a better tire.

Car has so much front steering had to dial it out a little...

Overall very impressed the front real makes this car...

Finally managed to do some testing.
First tires:
Tire rear soft seems to be pink-like
Super grip rear tire is grey/white-ish.
L-rubber front medium is magenta-ish.

Combo what worked well for me was Tire rear soft and the front mediums.
Super grip rear with the front mediums made the car have too much steering.

To gain steering throughout the turn, I dumped the stabiliser and the car worked very well. Rest is std kit.
I did however manage to loose one of the bottom podplate screws and the other 3 were loose.
Center shock is leaking, I was advised to use green slime on the O-rings to counter this.

R12 shock leaks oil.

1.shock O-ring is slight small,
2. shock inner spacer hole is slight large,

solution.
1, I use tamiya air remover and shock oil.



Soak O-rings with shock oil in remover, and pump.
This dilate O-ring.

2, make a small hole with grue and drill (1.8mm) two spacer/1 shock.

We run indoor, ashphalt using VHT as goop so high traction.
