There is a non-official-off championship race this Saturday and Oval (sucks) this Sunday.

If you wanna get lots of lap time, you better go in the evenings from Wednesday to Friday.

You got it. With the camber links angled down, you have a roll center that is aggressive. Putting 3mm shims will make the car feel more neutral.

Start tinkering with springs and swaybars to change the stiffness of the car. Maybe try a stiffer front and see how you like it.

Sorry for not getting this but are you shimming the ball stud on the diff holder or the one on the C-hub?

And just for the record,
I bought this car to see if I liked on road racing. I actually bought one that I built with my 7 year old and then gave it to him.
I bought Camloopers rig that came with:

Alu diff mounts
Alu Steering

I ordered:
Floating servo mount
Front solid axle and outdrives
Sway bars front and rear
I find the ball links on the diff mounts have a tendency to strip out (I am almost never crashing now but my car took some abuse). So I will try fixing this by countersinking some screw from underneath the diff mounts and attach balls from the top that have inner threads (same as Ultimate). Then I'll be able to shim. If that does not work, I'll get the alu diff holders

After that, I think the upgrades are going to stop and we'll see if I am happy by tweaking the setup.

If I am still this addicted and in the B or A-mains by next year, I'll probably give this one to my 4 year old and get daddy an X-ray or something.

Oui. Vous avez raison

The most basic way to neutralize the roll center is to try and make the camber links parallel to the ground (or at least less angled). On the Sakura, this is most easily achieved by shimming the ball stud on the bulkhead (diff holder).

What's your rollout? We used to cut our foams down between 55mm-53mm to start.

67mm sounds like a full fat tire.

I would recommend cutting your tires. Even if the shocks were adjusted for the big tire diameter, your chassis would be "slammed" and the drive shafts would be at more of an upward angle, versus being more at parallel with the ground.

Well tonight 3 consecutive laps under 11 seconds...Quite an exploit for me!!
So I played with the gearing and timing. I am now at FDR 4.54 and advanced the timing around 5 degrees past the mechanical stop by grinding the tabs.
I get very good top speed and so much acceleration that my front end hops under WOT!!!

Good little XI

Zero s can take alot of hits. But is older model and alittle twitchy in the rear and a tad heavier. Well thats a start :-)
