Really understanding what to tone down or alter for the lower grip/speed is the element most are missing too.
We need Gilles to start posting again to explain why he moves his rear inner camber link up by 0.5mm* from Gran Canaria to Luxembourg (for example) and what effect it actually has and how it helped.

Adding height moves the instant away from the centerline and makes the car softer in roll. Removing height moves the instant center closer to the centerline and makes the car lean less.
It's a subtle change to change how much mid corner roll you have. You change it because a spring change is too drastic, or unwanted.

Chassis change significant enough to skip X and straight to 419...
New gear diff probably like the evo6 design

What's "wrong" is that the chassis is too stiff, probably because Tamiya have used too-good quality materials - the dimensions match rival cars but the result lacks the required flex. My car has always gone better with screws removed, but I'm never happy removing screws. Personally speaking I'm happy with the diff (after a little work) so curious as to how the evo6 differs.

From the few pics from the latest ETS round I have seen the car looks pretty much the same. (Bulkheads, arms motor mount etc) Obviously the diff could all be internal and be an easy replacement for current racers, as would a softer chassis weave.
I race on carpet so a more flexible car isn't really what I would want, my 418 has been exceptional for me and provided the best winning streak I've had in all my years of racing. So much so, that its the car that the other top guys are either buying (when in stock) or waiting to see what the next revision is.
However I run the opposite of theTRF guys, carpet and 17.5 blinky so the revisions for them sound like it's making a big difference.

Interestingly, Jilles kept running the standard car for most of the day....
"For the final qualifier he will switch to a similar set-up to that being used by Rheinard. Having run a pretty standard car so far he will also run some prototype parts which he said Wilck & Rheinard have shown to improve the car."
I can't find any pictures of the cars in detail on the ETS site - anyone got a link?

The new car has different top deck, chassis, bulkheads and diff, apparently the single biggest change has been the diff wich has more oil volume and smoother gears. They had runner timed laps and found 0.2s just with the diff change (don't think that was here)

Wow - just from a diff....!
New bulkheads too - basically throw out the whole spine then.
Here's hoping for a 418WE/V6 then

Interesting that the big change may be the diff. Certainly a diff that responds inconsistently could explain the issues with rear traction, and could also explain why some people have been running very heavy oils in the rear.

Be great to see a good quality pic Skiddins the few I have seen are just incidental ones (driver pics and the car on the table).
The diff will be great and an easy upgrade. I wonder if the upper bulkheads are higher as some setups I've seen have large upper link shim settings.
