Dale upper link is as you say on a pan car. I think the camber gain change is the biggest component.
For exit steering try less rear droop.

Made a few changes, and we had a nice warm day here in the UK so ideal for another run.
Initially tried:
- Less reactive castor
- More castor (7deg)
- New diff balls
It felt a little better, but still short of traction. I then tried:
- More angle on the main shock (nose down).
- Diff backed off
- Less punch on ESC
That was a decent improvement, the car now feels nice throughout the lap. I'll probably go a bit more in this direction, (e.g. thinner oil, softer spring) as more traction will always help at this track.

It's a touch unstable on the straight, but the front wheels are almost parallel, so some toe-out should sort that.
Thanks for the tips and hints

Try it out, it's likely the easiest change to make.

That was released last September. What they just released was a .030 regular weight version of the body.

Hi Roy ,
Would it be ok to start the front height at 6 and the rear at 5.5 ?
Advance thx,
John

Reverse that, Front 5.5 and rear at 6

Yes - from experience, NEVER run a forward rake (rear higher than front) . . . straaaaaange behaviors occur then. . .

We still race F1 wide foam on asphalt here. It is similar to your pro ten style cars. There has been a breakthrough in foam tyre technology in the last few years - I'm not sure if you can get something equivalent for pro10, but the Kawada P rubber, Zen Omega or maybe TRG TZ tyres, seem to be a step up on other foam we have tried outdoors on asphalt (we don't use traction compound)
